Principle of Operation<br />

Evapco was the first to develop a closed circuit cooler with Patented<br />

Optimized Technology*. The warm process fluid enters the coil of the closed<br />

circuit cooler. Through both sensible and latent heat transfer, the heat from<br />

the process fluid in the coil is transferred to the cold spray water that floods<br />

over the tubes. Having gained heat from the coil, the spray water is then<br />

collected in the cold water basin and circulated up to the water distribution<br />

system by the spray pump. The warmed spray water is then distributed as a<br />

thin film over the extended fill surface for maximum cooling efficiency. The<br />

fan system operates simultaneously, moving large volumes of air through the<br />

unit in a direction opposite the falling water. The air and water contact<br />

directly across the fill surface whereupon a small portion of the spray water is<br />

evaporated. The air is then discharged from the unit as a warm and saturated<br />

stream with a <strong>final</strong> dissipation of heat to the atmosphere. The spray water<br />

exits the fill section as a cooled fluid where it is focused on the coil at a high<br />

flow rate, and floods across in a repeat cycle.<br />

Patented EVAPAK Fill<br />

The patented EVAPAK fill is specially designed to induce highly turbulent<br />

mixing of the air and water for superior heat transfer. The fill section<br />

is constructed of polyvinyl chloride (PVC) sheets which are<br />

thermally formed into a cross flute design. The<br />

individual fill sheets are bonded together to<br />

form rigid fill blocks. The fill blocks are then<br />

stacked within the unit’s protective casing. The<br />

structural strength of the assembled fill pack<br />

enables it to be used as a working platform.<br />

EVAPAK fill is impervious to rot and decay, and<br />

is self-extinguishing with a flame spread rating<br />

of 5 per ASTM Standard E84-81a.<br />

Sensi-Coil ® Technology (US Patent #7,296,620)<br />

Sensi-Coil ®<br />

The Sensi-Coil ® , exclusive on the <strong>ESWA</strong><br />

closed circuit cooler, features the maximum<br />

amount of Thermal-Pak elliptical tubes<br />

packed closely together in a coil<br />

arrangement designed with over 20%<br />

additional coil surface area.<br />

Evapco’s coils are manufactured within the<br />

most stringent of quality control procedures. Each circuit consists of high<br />

quality steel tubing formed into a continuous serpentine circuit. Each circuit<br />

is then inspected and tested prior to being welded into a framed coil<br />

assembly. The coil assembly is then pneumatically tested at 400 psig under<br />

water to ensure its integrity. The entire coil assembly is then hot-dip<br />

galvanized for industrial strength corrosion protection.<br />

NOW Evapco offers the TITAN COIL. Manufactured from type 304L<br />

Stainless Steel, the TITAN COIL is manufactured using Evapco’s patented<br />

elliptical tube Sensi–Coil ® design upgraded to Xtra Tough construction<br />

featuring: Xtra Durability, Xtra Corrosion Resistance, and an Xtra long<br />

5 YEAR coil warranty as standard.<br />

In its continuing <strong>com</strong>mitment to be the leaders in evaporative cooling equipment design and services,<br />

<strong>EVAPCO</strong> <strong>ESWA</strong> Closed Circuit Coolers are now Independently Certified to withstand both Seismic<br />

and Wind Loads in ALL Geographic Locations and Installations in accordance with IBC 2006.<br />

What is IBC?<br />

International Building Code<br />

The International Building Code (IBC) is a <strong>com</strong>prehensive<br />

set of regulations addressing both the structural design<br />

and the installation requirements for building systems –<br />

including HVAC and industrial refrigeration equipment.<br />

The IBC is intended to replace BOCA’s The National<br />

Building Code, ICBO’s Uniform Building Code and SBCCI’s<br />

Standard Building Code.<br />

Compared to previous building codes that considered<br />

only the building structure and <strong>com</strong>ponent anchorage,<br />

the requirements contained within the IBC address<br />

anchorage, structural integrity, and the operational<br />

capability of a <strong>com</strong>ponent following either a seismic or<br />

wind load event. Simply stated, the IBC code<br />

provisions require that evaporative cooling<br />

equipment, and all other <strong>com</strong>ponents permanently<br />

installed on a structure, must be designed to meet<br />

the same seismic and wind load forces as the<br />

building to which they are attached.<br />

How Does IBC 2006 Apply to Closed<br />

Circuit Coolers?<br />

Based on the project zip code and site design factors, calculations<br />

are made to determine the equivalent seismic<br />

“g force” and wind load (in pounds per square foot – psf)<br />

on the unit. The closed circuit cooler must be designed to<br />

withstand the greater of either the seismic or wind load.<br />

The <strong>ESWA</strong> is offered with a choice of TWO structural<br />

design packages:<br />

• Standard Structural Design – For projects with<br />

≤ 1.0g seismic or 60 psf wind loads<br />

• Upgraded Structural Design – Required for<br />

projects with > 1.0g seismic or 145 psf max wind loads<br />

More than 80% of the United States has design criteria<br />

resulting in a seismic design force of 1.0g or below. These<br />

sites will be provided with the standard <strong>ESWA</strong> structural<br />

design. An upgraded structural design is available for<br />

installations with design criteria resulting in “g forces”<br />

IBC COMPLIANCE<br />

greater than 1.0g. The highest “g force” location in<br />

North America is 5.12g. The highest wind load shown on<br />

the maps is 170 mph, which is approximately equal to 145<br />

psf velocity pressure. Therefore, the upgraded structural<br />

design package option for the <strong>ESWA</strong> is<br />

designed for 5.12g and 145 psf making it applicable<br />

to ALL building locations in North America.<br />

Seismic Design<br />

The attached chart from the US Geological Survey<br />

Website (http://www.usgs.gov/) shows the potential seismic<br />

activity in the United States. Buildings constructed in<br />

the red, orange and yellow areas of the map may require<br />

the upgraded <strong>ESWA</strong> construction design based on the site<br />

seismic design factors and should be reviewed closely.<br />

Critical use facilities, such as hospitals, are also more likely<br />

to require the upgraded design.<br />

The project architect or civil engineer is responsible for<br />

determining the seismic design factors to be used for the<br />

building design. A mechanical consulting engineer and/or<br />

design build contractor then applies these factors to a<br />

series of charts and graphs to determine the appropriate<br />

seismic design factors based on the location of the installation<br />

and ultimately the “importance” of the facility.<br />

The specific factors necessary for seismic design as well as<br />

a sample seismic calculation are shown on pages 6 and 7.<br />

Wind Design<br />

The IBC 2006 code book includes a map of basic wind<br />

speed (3-second gust) by contour lines. However, local<br />

regulations may be more stringent than these published<br />

speeds. The specific factors necessary for wind load as well<br />

as a sample wind load calculation are shown on Page 8.<br />

Whichever design force - seismic or wind - is more<br />

severe for the building, governs the design of the<br />

building and all attached equipment.<br />

Design Implementation<br />

<strong>EVAPCO</strong> applies the given seismic and wind load information<br />

provided by the mechanical consulting engineer to<br />

determine the equipment design necessary to meet IBC<br />

requirements. This process ensures that the mechanical<br />

equipment and its <strong>com</strong>ponents are <strong>com</strong>pliant per the<br />

provisions of the IBC as given in the plans and specifications<br />

for the project. For design build projects, <strong>EVAPCO</strong> is<br />

equipped to look up the information and submit the<br />

resulting loads for approval.<br />

Independent Certification<br />

Per the most recent edition of the code, the <strong>EVAPCO</strong><br />

<strong>com</strong>pliance process included an exhaustive analysis by an<br />

independent approval agency. As required by the<br />

International<br />

Building Code,<br />

<strong>EVAPCO</strong> sup-<br />

plies a certificate<br />

of <strong>com</strong>pliance<br />

as part of<br />

its submittal<br />

documents. The<br />

that the equipment has been independently tested and<br />

analyzed in accordance with the IBC seismic and wind<br />

load requirements. Evapco has worked closely with the<br />

independent approval agency, The VMC Group, to <strong>com</strong>plete<br />

the independent equipment testing and analysis.<br />

If the seismic “g force” and wind “psf” load requirements<br />

for the project site are known, <strong>EVAPCO</strong>’s online equipment<br />

selection software, iES, will allow you to choose the<br />

required structural design package – either standard construction<br />

or upgraded construction.<br />

If the project requirements are unknown, the following<br />

calculations must be <strong>com</strong>pleted.<br />

For further questions regarding IBC <strong>com</strong>pliance, please<br />

contact your local <strong>EVAPCO</strong> Representative or visit<br />

www.evapco.<strong>com</strong>.<br />

When using the <strong>EVAPCO</strong> selection software to make a<br />

selection, these calculations are already incorporated<br />

into the selection process. Simply enter the required<br />

seismic factors and the Seismic Design Force and Wind<br />

Load will be calculated automatically!!<br />

Seismic Load Calculations<br />

The data required to calculate the seismic load are:<br />

Occupancy Category – I, II, III or IV depending on the<br />

nature of the building occupancy. Table 1604.5 in the IBC<br />

2006 Code Book defines each of the four categories in<br />

detail. In summary the four categories are:<br />

• Category I - structures that represent a low hazard<br />

to human life in the event of a failure.<br />

• Category III - structures that represent a substantial<br />

hazard to human life in the event of a failure.<br />

• Category IV - structures designated as essential<br />

facilities.<br />

• Category II - any structures not listed in I, III or IV.<br />

Site Classification – A, B, C, D, E or F based on the types<br />

of soil and their engineering properties. Table 1613.5.2 in<br />

the IBC 2006 Code Book defines each of the categories in<br />

detail. IBC specifies site class “D” when soil properties are<br />

unknown.<br />

Maximum Spectral Response Acceleration (Ss) –<br />

Numerical value found using the U.S. Geological (USGS)<br />

data based on the Zip Code of the project. This data<br />

point can be determined using the Ground Motion<br />

Parameter Calculator at http://www.usgs.gov/. Note the<br />

calculator assumes a site classification of B for the 0.2 second<br />

maximum Ss. The site coefficient (Fa), defined below,<br />

will correct for the actual site classification.


Site Coefficient (Fa) – Values ranging from 0.8 to 2.5<br />

determined based on the Ss and the Site Classification.<br />

Table 1613.5.3(1) in the IBC 2006 Code Book defines<br />

these values.<br />

value using the values for Ss and Fa.<br />

(Fa)(Ss)<br />

Amplification Factor (ap) – 2.5 for flexible <strong>com</strong>ponents<br />

or flexibly attached <strong>com</strong>ponents. Due to its low inherent<br />

natural frequencies, most evaporative cooling equipment<br />

falls under the definition of flexible. Therefore the<br />

default for Closed Circuit Coolers is 2.5. See Table 13.6-1<br />

in the American Society of Civil Engineers (ASCE)<br />

Standard 7-05, to which IBC often references, for more<br />

information.<br />

Response Modification Factor (Rp) – 2.5 for non-isolated<br />

evaporative cooling equipment. 2.0 for vibration isolated<br />

evaporative cooling equipment. Table 13-6.1 of<br />

ASCE 7-05 provides additional information.<br />

Component Operating Weight (Wp) – This weight term<br />

has been removed from the equation below, because<br />

<strong>EVAPCO</strong> is expressing the force in terms of g’s and not lbs.<br />

Importance Factor (Ip) – 1.5 for Occupancy Category IV,<br />

life safety <strong>com</strong>ponents required to function after a seismic<br />

event or <strong>com</strong>ponent containing hazardous content.<br />

1.0 for all other <strong>com</strong>ponents. ASCE 7-05 Section 13.1.3<br />

provides additional detail on importance factors.<br />

Installation Location (Z/h) – 0 for units installed at<br />

ground level. 1.0 for units installed on a rooftop. Per<br />

ASCE 7-05 Section 13.3, z = the height of the point of<br />

attachment of the <strong>com</strong>ponent and h = the relative roof<br />

height.<br />

Seismic Design Force, (Fp) – “G-force” that the unit<br />

must be able to withstand. This number is calculated<br />

using the factors described above. The <strong>ESWA</strong> is offered<br />

with a choice of two structural design packages, consisting<br />

of:<br />

– Standard Structural Design ≤ 1.0g<br />

– Upgraded Structural Design – up to 5.12g (the<br />

maximum value for North America)<br />

IBC COMPLIANCE<br />

Seismic Load Sample Calculation<br />

The following example demonstrates the procedure for<br />

determining which structural design package a<br />

Community Hospital located in Charleston, SC (zip code<br />

29401) would require under the latest version of IBC. In<br />

this example, the closed circuit cooler will be installed on<br />

a roof, approximately 60 feet above grade. The unit will<br />

also be installed with a vibration isolation system.<br />

Step 1: Calculate the Design Spectral Response<br />

Acceleration (SDS)<br />

Where:<br />

SS = 1.495; using the USGS Ground Motion Parameter<br />

Calculator<br />

Fa = 1.0; from Table 1613.5.3(1) in the IBC 2006 Code<br />

Book assuming a Site Classification of D<br />

Step 2: Calculate the Seismic Design Force (Fp )<br />

Ip = 1.5; the default for life safety <strong>com</strong>ponents<br />

z/h = 1.0; the default for units on a rooftop<br />

In order to meet Code requirements, the unit and its<br />

anchorage must be constructed to withstand 2.24g. This<br />

will require that the upgraded structure option be chosen<br />

to meet the seismic requirements of this project. Because<br />

the seismic load requires the upgraded structural design,<br />

the wind load calculation results will not change the<br />

design and are not required for this analysis.<br />

Wind Load Calculations<br />

The data required to calculate the wind load are:<br />

Basic Wind Speed (V) – Numerical value, in miles per<br />

hour (mph) found in ASCE 7-05 Figures 6-1 (A,B,C).<br />

Wind Directionality Factor (Kd) – 0.85 for building<br />

<strong>com</strong>ponents and cladding. Table 6-4 of ASCE 7-05 provides<br />

additional information.<br />

Occupancy Category – I, II, III or IV depending on the<br />

nature of the building occupancy. Table 1604.5 in the<br />

IBC 2006 Code Book defines each of the categories in<br />

detail. This is the same Occupancy Category used in<br />

Seismic calculations.<br />

Importance Factor (I) – Numerical value between 0.77<br />

and 1.15 based on the Basic Wind Speed and the<br />

Occupancy Category. These values are found in Table 6-1<br />

of ASCE 7-05.<br />

Exposure Category – B, C or D as defined in Section<br />

6.5.6.3 of ASCE 7-05.<br />

Component Elevation (z) – The anchorage height of<br />

the unit in feet.<br />

Low Energy As Standard<br />

The <strong>ESWA</strong> stands apart as being the most energy efficient<br />

closed circuit cooler on the market today. This efficiency, in<br />

terms of lower fan horsepower, translates directly to lower<br />

operating costs…significantly lower operating costs. With<br />

the <strong>ESWA</strong> installed, customers can realize immediate energy<br />

savings which continue each and every year for the life of<br />

the equipment.<br />

• Replace inefficient units:<br />

The potential for energy savings alone is often enough to<br />

justify replacing inefficient fluid coolers with high<br />

efficiency models. As an example, a 250 ton centrifugal<br />

fan fluid cooler with 80 HP worth of fan motors can be<br />

replaced by an <strong>ESWA</strong> model with a fan motor size of<br />

only 15HP. This tremendous reduction in fan motor size<br />

offers annual savings of $16,530 per year based on 3,500<br />

hours of operation and an electric rate of $0.09/kWh.<br />

• New Product Comparison:<br />

When <strong>com</strong>paring the cost of new equipment, energy<br />

efficiency and consumption are important factors for<br />

determining the total product cost. Units having a<br />

lower first cost but higher energy requirement are more<br />

expensive to operate and normally end up costing the<br />

customer more over the life of the equipment.<br />

• Smaller Footprint, Lower Horsepower:<br />

As an example, a typical induced-draft 200 ton** cooler<br />

can require a 12’ x 12’ footprint, 20 HP fan motor, and 5<br />

HP pump. The same load can be ac<strong>com</strong>plished in an<br />

<strong>ESWA</strong> with an 8.5’ x 12’ footprint, 7.5 HP fan motor, and<br />

7.5 HP pump.<br />

**Calculated using 3 GPM of Water at 100°F/90°F/78°F per ton.<br />

Low Sound As Standard<br />

In addition to being the most energy efficient axial fan<br />

fluid cooler, the <strong>ESWA</strong> is also the quietest. At a distance of<br />

five feet above the fan, the <strong>ESWA</strong> has sound levels that<br />

are up to 13dBA less than other axial fan fluid coolers of<br />

equal capacity. Additionally, the coil sits just above the<br />

basin floor breaking the water fall and reducing water<br />

noise to the point where casual conversation is possible at<br />

only five feet from the unit…even with the fan running on<br />

high speed.<br />

Research and Development<br />

Evapco's research and development team considered the<br />

basic principles of heat transfer to develop the patented<br />

Optimized Technology that was used in the ESW closed<br />

circuit cooler. Optimized Technology <strong>com</strong>bines “latent”<br />

heat transfer over the fill and “sensible” heat transfer over<br />

the coil to maximum heat transfer while minimizing scale<br />

buildup on the coil.<br />

The <strong>ESWA</strong> closed circuit cooler was developed to take<br />

Optimized Technology to the next level. The <strong>ESWA</strong><br />

features more capacity than ever before, 12-24% more<br />

capacity per footprint on average. This is done by using<br />

Evapco's new higher-density Sensi-Coil Technology. By<br />

using this new coil design (US Patent # 7,296,620), and<br />

higher water loadings over the coil, Evapco has achieved<br />

significant performance gains over other closed circuit<br />

coolers. This means more performance, a smaller<br />

footprint, and less energy.<br />

Other benefits of this unique counterflow<br />

design:<br />

• The coil is easily piped at ground level.<br />

• The coil is easily inspected and accessible at ground level<br />

via removable cover panels around the unit.<br />

• Discharge hood with dampers are not required...the<br />

dense coil pack and sheltered enclosure around the coil<br />

reduces heat loss and eliminates natural drafts across<br />

the coil.<br />

Counterflow... Optimum Design for<br />

Freezing Climates<br />

The counterflow design of the <strong>ESWA</strong> Closed Circuit Cooler is<br />

well suited for winter operation. The fill section is totally<br />

encased and protected from freezing winds thus inhibiting<br />

ice formation on the fill section. The even temperature<br />

gradient of the counterflow design further improves winter<br />

operability by eliminating cold spots.<br />

Evapco's counterflow design solves the problem of fill<br />

collapse due to ice formation.<br />

Water Sight Tight Air Inlet Louver*<br />

Evapco's innovative air inlet louvers are both water and sight<br />

tight to ensure that the water stays in and the sunlight stays<br />

out of the cold water basin. Using extensive <strong>com</strong>putational<br />

fluid dynamics modeling, Evapco engineers developed a<br />

louver to improve “splash resistance” while maximizing<br />

airflow. The resulting design maximizes thermal performance<br />

while minimizing water loss. This sight tight design also<br />

inhibits algae growth more effectively than previous designs.<br />

Evapco’s louver design solves the problem of the circulating<br />

water and heat transfer surfaces being directly exposed to<br />

external contaminants and the harsh surroundings.<br />

Water Distribution System<br />

The water distribution system is enclosed and <strong>com</strong>pletely<br />

protected by the casing panels and drift eliminators. The<br />

eliminators also function as effective debris screens which block<br />

sunlight and prevent debris from entering the spray system.<br />

The water distribution system is made with non-corrosive<br />

materials including schedule 40 PVC pipe and durable ABS<br />

plastic water diffusers or the EvapJet distribution system<br />

(14’ wide models).<br />

The spray branch piping is easily removed and designed with<br />

threaded end-caps for easy cleaning. The water diffusers<br />

have wide openings with anti-sludge rings to prevent<br />

clogging from sediment and debris.<br />

Evapco’s design avoids the problems of biological growth<br />

and clogging that can occur due to a water distribution<br />

system that is open with direct exposure to the surroundings.<br />

Efficient Drift Eliminators**<br />

The New <strong>ESWA</strong> is provided with an efficient drift eliminator<br />

system that effectively reduces entrained water droplets<br />

from the air discharge to less than 0.001% of the spray water<br />

flow rate.<br />

The eliminators are constructed of non-corrosive PVC with a<br />

multi-pass design for maximum drift reduction. They are<br />

assembled in modular sections for easy removal and access to<br />

the water distribution system.<br />

In addition to reducing drift the eliminators also function as<br />

effective debris screens which protect the spray system from<br />

sunlight and debris.<br />

M AINTENANCE A DVANTAGES<br />

Easy Maintenance Basin Design<br />

The cold water basin is perhaps the most important area for maintenance in an evaporative cooler. Service mechanics who<br />

work on this equipment know that dirt, debris and silt all settle out in the basin. Because basin maintenance is important and<br />

should be performed regularly, Evapco designed the basin to make inspection, cleaning and flushing as easy as possible.<br />

<strong>EVAPCO</strong>’s basin is designed for quick and easy access with the following valuable features:<br />

Easy Access<br />

The cold water basin section is easily accessible from<br />

ground level. The basin is provided with solid access panels<br />

which are designed to protect the basin water and heat<br />

transfer coil from direct exposure to sunlight and debris.<br />

The access panels are light-weight and easy to remove.<br />

With the access panels removed a service mechanic has<br />

<strong>com</strong>plete access to the basin floor, heat transfer coil, float<br />

assembly and pump strainer.<br />

Clean Pan Basin Design<br />

The basin of the <strong>ESWA</strong> is sloped toward a depressed area<br />

where the drain is located. With the "Clean Pan" design, it<br />

is easy for a service mechanic to flush the pan without<br />

getting wet feet. Other fluid cooler designs may necessitate<br />

getting inside of the unit for <strong>com</strong>plete cleaning.<br />

Stainless Steel Strainers<br />

The <strong>EVAPCO</strong> standard for many years, the stainless steel<br />

strainer is one <strong>com</strong>ponent that is subject to excessive<br />

wear and corrosion. With stainless steel construction this<br />

<strong>com</strong>ponent will last the life of the unit.<br />

Easy Maintenance Drive System<br />

The Evapco POWER-BAND drive system utilized on the <strong>ESWA</strong> Closed Circuit Cooler is the easiest belt drive system to<br />

maintain in the industry. Unlike other designs, there is no need to enter the cold water basin to climb up the plenum for<br />

access to motors, bearings or belts. All routine and periodic maintenance on the drive system can be safely performed from<br />

the exterior of the unit. The most significant benefits and features of Evapco’s drive system are detailed below.<br />

Models with Motors Mounted Externally<br />

Models <strong>ESWA</strong>-77, 102 and 153<br />

The fan motor and drive assembly are designed for easy service and<br />

adjustment from the unit’s exterior. The Totally Enclosed, Fan Cooled (TEFC)<br />

fan motor is mounted external to the unit with a protective cover which<br />

swings aside for maintenance. A large access door adjacent to the fan<br />

motor swings open enabling easy access to the fan drive system. The belt<br />

tension can be checked and adjusted easily from the outside of the unit.<br />

The fan shaft bearings also have their lubrication lines extended to the<br />

access door for added convenience. Note, these motors are typically<br />

installed in the field to reduce shipping costs. Contact your Evapco sales<br />

representative for factory mounting options.<br />

Models with Swing-Out Motors<br />

Models <strong>ESWA</strong>-144, 216, 336 and 672<br />

M AINTENANCE A DVANTAGES<br />

The fan motor is Totally Enclosed, Air Over (TEAO) and specifically designed for evaporative cooling applications. The motor<br />

is mounted inside of the unit on an adjustable base that enables the motor to swing outside the unit for easy access. The belt<br />

tension is easily checked and adjusted from outside the access door. Evapco provides a special tool for belt adjustment which<br />

also functions as a locking mechanism for the motor base adjustment. Lubrication lines for the fan shaft bearings are also<br />

extended to the access door for added convenience.<br />

Internal motor... ...with swing-out base<br />

With all periodic and routine maintenance for the drive system performed from the side<br />

of the unit, Evapco drive systems are the most serviceable in the industry.<br />

Sloped access ladders, working<br />

platforms and motor davits are<br />

available as options to make<br />

maintenance a breeze. See page 26,<br />

External Platforms & Motor Davits<br />

External platforms provide a sturdy base for access to the<br />

drive <strong>com</strong>ponents, water distribution and drift eliminators.<br />

Constructed from heavy gauge galvanized steel, the<br />

platform mounts easily to the unit and requires no external<br />

support. The platform option includes a vertical aluminum<br />

ladder and meets all applicable OSHA requirements. A safety<br />

cage for the ladder is also available if required for the<br />

installation.<br />

The motor davit option is an economical option which<br />

eliminates the need for a crane in the event that a fan<br />

motor has to be removed. The service mechanic only needs a<br />

chain-fall or <strong>com</strong>e-along for easy removal of these heavy<br />

items. The motor davit is constructed from heavy duty<br />

aluminum with easy mounting to the unit in the field.<br />

Electric Water Level Control<br />

An electric water level control package is available as an<br />

alternative to the standard mechanical makeup valve and<br />

float ball. This package provides accurate control for the<br />

basin water level and does not require field adjustment,<br />

even under varying operating conditions.<br />

The control was designed by <strong>EVAPCO</strong> and is manufactured<br />

exclusively for <strong>EVAPCO</strong>. It consists of multiple heavy duty<br />

stainless steel electrodes mounted external to the unit<br />

in a vertical stand<br />

pipe. For winter<br />

operation, the<br />

stand pipe must<br />

be wrapped with<br />

electric heating<br />

cable and insulated to<br />

protect it from freezing.<br />

The weather protected slow<br />

closing solenoid valve(s) for the<br />

makeup water connection is factory<br />

supplied and is ready for piping to a<br />

water supply.<br />

Stainless Steel Basin<br />

The modular design of Evapco coolers allow specific areas to<br />

be targeted for increased corrosion protection. The basin<br />

area of the cooler will experience silt build-up and turbulent<br />

mixing of air and water making it the part of the unit that is<br />

most prone to corrosion. This section also serves as the<br />

foundation of the unit providing critical support to the upper<br />

sections. Evapco recognizes the need for corrosion<br />

protection in this area and offers a Stainless Steel Basin as an<br />

affordable option. This option provides Type 304 or 316<br />

stainless steel for the entire basin area including the support<br />

columns and louver frames.


Super Low Sound Fan<br />

9–15 dB(A) Reduction versus Standard Fan!<br />

The Super Low Sound Fan<br />

offered by <strong>EVAPCO</strong> uses an<br />

extremely wide chord blade<br />

design for very sound sensitive<br />

applications where the lowest<br />

sound levels are required. The<br />

fan is one-piece molded heavy<br />

duty FRP construction utilizing<br />

a forward swept blade design.<br />

The Super Low Sound fan is capable of reducing the unit<br />

sound pressure levels by 9 dB(A) to 15 dB(A), depending on<br />

specific unit selection and measurement location with no<br />

impact to thermal performance. The fans are high efficiency<br />

axial propeller type.<br />

Low Sound Fan<br />

4–7 dB(A) Reduction!<br />

The Low Sound Fan offered by <strong>EVAPCO</strong> uses a wide chord<br />

blade design for sound sensitive applications where low<br />

sound levels are desired.<br />

Low Sound Fan construction<br />

uses aluminum blades and<br />

a steel fan hub. The Low<br />

Sound Fan is capable of<br />

reducing the unit sound<br />

pressure levels by 4 dB(A)<br />

to 7dB(A), depending on<br />

specific unit selection and<br />

measurement location<br />

with a minimal impact to thermal performance. The fans<br />

are high efficiency axial propeller type.<br />

Fan Discharge Sound Attenuation<br />

Up to 10 dB(A) Reduction!<br />

The <strong>ESWA</strong> Fan Discharge Attenuator offered by <strong>EVAPCO</strong> is an<br />

additional option available to further reduce the sound level<br />

of the unit. The attenuator can be used with the standard<br />

<strong>ESWA</strong> fan or in <strong>com</strong>bination with the Low Sound Fan option.<br />

The discharge attenuator is a factory-assembled straight-sided<br />

discharge hood designed to reduce overall discharge sound<br />

levels at full fan speed by 5 dB(A) to 10 dB(A), depending<br />

on specific unit selection and measurement location with a<br />

minimal impact to thermal performance. It is constructed of<br />

G-235 galvanized steel as standard (options available for Type<br />

304 stainless steel) and includes insulated walls and a low<br />

pressure drop baffling system that is acoustically lined with<br />

Electric Basin Heaters<br />

Electric immersion heaters are available factory-installed in<br />

the basin of the cooler. Standard Heaters are sized to<br />

maintain a +40°F pan water temperature with the fans and<br />

pumps off and an ambient air temperature of 0°F. The<br />

heater option includes a thermostat and low-water<br />

protection device to control the heater and to prevent it<br />

from energizing unless they are <strong>com</strong>pletely submerged. All<br />

<strong>com</strong>ponents are in weather proof<br />

enclosures for outdoor use. The<br />

heater power contactors and<br />

electric wiring are not<br />

included as standard. Refer<br />

All <strong>ESWA</strong> models <strong>com</strong>e standard with premium efficient,<br />

inverter capable fan motors that can be used with variable<br />

frequency drive (VFD) systems for precise capacity control.<br />

VFD systems can control the speed of a fan motor by<br />

modulating the voltage and frequency of the input electrical<br />

signal. When connected to a building automation system a<br />

VFD can receive signals telling it to slow down the fan motor<br />

as the capacity of the closed circuit cooler exceeds the cooling<br />

demand and speed it back up when demand increases. This<br />

popular method of capacity control can yield significant<br />

energy savings.<br />

Evapco offers two-speed fan motors as an option for<br />

alternative capacity control. In periods of lightened loads or<br />

reduced wet bulb temperatures the fans can operate at low<br />

speed providing about 60% of full speed capacity yet<br />

consuming only about 15% of full speed power. In addition<br />

to the energy savings the sound levels of the unit can be<br />

greatly reduced by operating at low speed. These motors do<br />

not require the use of VFD systems however they can only<br />

operate at two speeds: full or low.<br />

Re<strong>com</strong>mended Steel Support<br />

The re<strong>com</strong>mended support for <strong>EVAPCO</strong> Closed Circuit<br />

Coolers is structural “I” beams located under the outer<br />

flanges and running the entire length of the unit. The<br />

unit should be elevated to allow access underneath the<br />

unit and to the roof below. Mounting holes 3/4” in<br />

diameter are located in the bottom flanges of the pan<br />

section to provide for bolting to the structural steel.<br />

(Refer to certified drawings from the factory for bolt<br />

hole locations).<br />

Beams should be level before setting the unit in place.<br />

Do not level the unit by shimming between the unit and<br />

the structural steel. Dimensions, weights, and data are<br />

subject to change without notice. Refer to the factory<br />

certified drawings for exact dimensions.<br />

NOTE: Consult IBC 2006 for required steel support layout<br />

Freeze Protection for the Recirculating<br />

Water System<br />

If the units are installed in a cold climate and operated<br />

year round, freeze protection must be provided for the<br />

recirculating water system in the unit as well as for the<br />

heat exchanger coil.<br />

The surest way to protect the recirculating water system<br />

from freezing is with a remote sump. The remote sump<br />

should be located inside the building and below the unit.<br />

When a remote sump arrangement is selected, the spray<br />

pump is provided by others and installed at the remote<br />

sump. All water in the closed circuit cooler basin should<br />

drain to the remote sump when the spray pump cycles off.<br />

Other freeze protection methods are available when a<br />

remote sump is not feasible. Electric pan heaters or steam<br />

or hot water coils can be used to keep the pan water<br />

from freezing when the unit cycles off. Water lines to and<br />

from the unit, spray pump and related piping should be<br />

heat traced and insulated up to the overflow level in<br />

order to protect from freezing.<br />

Freeze Protection for the Heat<br />

Exchanger Coil<br />

Units installed in climates subject to freezing conditions must<br />

be adequately protected against freezing of the heat<br />

exchanger coil and pan water.<br />

The simplest and most effective way of protecting the heat<br />

exchanger coil from freezing is to use an inhibited ethylene or<br />

propylene glycol solution.<br />

If a glycol solution cannot be used both of the following<br />

conditions must be met:<br />

1) Maintain sufficient process heat load through the coil<br />

such that the coil temperature is kept above 50°F. If the<br />

process load cannot support 50°F fluid, an auxiliary heat<br />

load should be applied when freezing conditions exist.<br />

Refer to Table 1 for coil heat loss data.<br />

2) Design flow should be maintained through the coil<br />

whenever possible. If this is not possible, refer to Table 2<br />

for minimum re<strong>com</strong>mended flow rates.<br />

If the coil is not protected with an antifreeze/glycol solution,<br />

automatic drain valves and air vents should be installed in<br />

the coil supply and return piping. The drain valves and<br />

piping should be heat traced and sized for quick drainage of<br />

the coil. The drain valves and air vents should be signaled to<br />

drain the coil if the fluid flow stops or drops below 40°F in<br />

freezing conditions.<br />

Draining the coil as an emergency method of freeze<br />

protection is acceptable, however it is not re<strong>com</strong>mended as<br />

standard practice. Frequent draining of the coil exposes the<br />

inner tube surface to oxygen which results in corrosion. If the<br />

coil is drained for emergency freeze protection, it should not<br />

be left empty for extended periods of time.<br />

Design<br />

<strong>EVAPCO</strong> equipment is constructed of the highest quality<br />

materials and designed to provide years of reliable service<br />

when properly installed and maintained. The following<br />

sections present items which must be considered prior to the<br />

selection and installation of equipment.<br />

Equipment Layout Planning<br />

Proper equipment layout is essential to ensure that the fluid<br />

cooler operates at its rated capacity. Since evaporative<br />

cooling equipment requires large quantities of fresh air for<br />

cooling, it is important that the unit be located where the air<br />

supply is fresh and unobstructed.<br />

The unit should also be located so that recirculation of the<br />

moist discharge air is minimized. Recirculation, also known<br />

as short-cycling, occurs when some of the warm, moist air<br />

discharge flows back to the unit’s air inlet. The recirculation<br />

effect results in higher wet bulbs to the unit, which has a<br />

negative impact on the unit’s field performance.<br />

Engineering Bulletin No. 311 presents the Layout Guidelines<br />

for Evapco cooling towers, fluid coolers and evaporative<br />

condensers. This bulletin is available from your local<br />

representative, or it can be downloaded from<br />

www.evapco.<strong>com</strong><br />

The closed circuit cooler should be located away from<br />

fresh air intakes, operable windows, kitchen exhaust,<br />

and prevailing winds directed toward public areas.<br />

Closed Circuit Applications<br />

Closed Circuit Coolers are designed to be used on<br />

"Closed Loop" systems where the cooling loop is<br />

sealed and pressurized. These units are not intended<br />

for use in "Open Systems" where the cooling fluid has<br />

atmospheric contact.<br />

If applied in open systems, the coil may corrode<br />

from the inside with rust deposition throughout the<br />

cooling loop.<br />

The cooling fluid must be <strong>com</strong>patible with the coil material;<br />

standard coils are fabricated from black steel with the outer<br />

surface hot dip galvanized.<br />

Piping<br />

Supply and return piping for fluid coolers should be designed<br />

and installed in accordance with generally accepted<br />

engineering practice. The piping layout should be<br />

symmetrical for systems with multiple units, and should be<br />

sized for a low water velocity and pressure drop.<br />

Since these units are intended for "Closed Loop" applications,<br />

the loop piping should include an expansion tank to allow for<br />

fluid expansion and to purge excess air from the system.<br />

The piping system should include air vents and drain valves at<br />

the coil piping so that the coil can be drained if the need arises.<br />

All piping external to the unit should be secured and<br />

anchored by properly designed hangers and supports. No<br />

external loads should be placed upon the coil connections<br />

nor should any pipe supports be anchored to the unit.<br />

A PPLICATIONS AND WATER Q UALITY<br />

Recirculating Water Quality<br />

Proper water treatment is an essential part of the<br />

maintenance required for evaporative cooling equipment. A<br />

well designed and consistently implemented water<br />

treatment program will help to ensure efficient system<br />

operation while maximizing the equipment’s service life. A<br />

qualified water treatment <strong>com</strong>pany should design a site<br />

specific water treatment protocol based on equipment<br />

(including all metallurgies in the cooling system), location,<br />

makeup water quality, and usage.<br />

Bleed off<br />

Evaporative cooling equipment requires a bleed or<br />

blowdown line, located on the discharge side of the<br />

recirculating pump, to remove concentrated (cycled up)<br />

water from the system. Evapco re<strong>com</strong>mends an automated<br />

conductivity controller to maximize the water efficiency of<br />

your system. Based on re<strong>com</strong>mendations from your water<br />

treatment <strong>com</strong>pany, the conductivity controller should open<br />

and close a motorized ball or solenoid valve to maintain the<br />

conductivity of the recirculating water. If a manual valve is<br />

used to control the rate of bleed it should be set to maintain<br />

the conductivity of the recirculating water during periods of<br />

peak load at the maximum level re<strong>com</strong>mended by your<br />

water treatment <strong>com</strong>pany.<br />

Water Treatment<br />

The water treatment program prescribed for the given<br />

conditions must be <strong>com</strong>patible with the unit’s materials of<br />

construction, including any galvanized <strong>com</strong>ponents. The<br />

initial <strong>com</strong>missioning and passivation period is a critical time<br />

for maximizing the service life of galvanized equipment.<br />

Evapco re<strong>com</strong>mends that your site specific water treatment<br />

protocol includes a passivation procedure which details water<br />

chemistry, any necessary chemical addition, and visual<br />

inspections during the first six (6) to twelve (12) weeks of<br />

operation. During this passivation period, recirculating<br />

water pH should be maintained above 7.0 and below 8.0 at<br />

all times. Batch feeding of chemicals is not re<strong>com</strong>mended.<br />

Control of Biological Contaminants<br />

Evaporative cooling equipment should be inspected regularly<br />

to ensure good microbiological control. Inspections should<br />

include both monitoring of microbial populations via<br />

culturing techniques and visual inspections for evidence of<br />

biofouling.<br />

Poor microbiological control can result in loss of heat transfer<br />

efficiency, increase corrosion potential, and increase the risk<br />

of pathogens such as those that cause Legionnaires ’ disease.<br />

Your site specific water treatment protocol should include<br />

procedures for routine operation, startup after a shut-down<br />

period, and system lay-up, if applicable. If excessive<br />

microbiological contamination is detected, a more aggressive<br />

mechanical cleaning and/or water treatment program should<br />

be undertaken.
