LOW INSTALLATION COSTS - CONTRACTOR SAVINGS<br />
The <strong>REP</strong>’s fit tight enclosures and match up with crossflow layouts, piping, and steel, while still offering<br />
the maintenance and operational advantages of EVAPCO’s induced draft counterflow cooling towers.<br />
Layout Savings<br />
The <strong>REP</strong> counterflow method of heat transfer is the most efficient in the industry, resulting in a plan area up to 35%<br />
less than a comparable sized crossflow tower. The <strong>REP</strong>’s smaller plan area enables it to be located in smaller, less<br />
costly enclosures.<br />
<strong>REP</strong> units draw air from all four sides, so it is ideal for tight replacement projects. The <strong>REP</strong> can be placed close to a<br />
surrounding wall with little or no effect on unit capacity. The <strong>REP</strong> ’s are ideal for matching existing crossflow layouts.<br />
Piping Savings<br />
All piping connections are on one end, thereby reducing piping costs and installation time. Conventional doubleflow<br />
crossflow cooling towers require two water inlet connections per cell. The counterflow <strong>REP</strong> design requires only one<br />
inlet connection per cell, thereby significantly reducing the expensive piping, piping support and flow balancing<br />
valves required with the crossflow design. The pressurized water distribution system in <strong>REP</strong> units do not require flow<br />
balancing valves.<br />

<strong>REP</strong> Simplified Piping<br />
Steel Savings<br />
The two cell <strong>REP</strong> units may be supported in two ways - see Option A and B below. In Option A, the two cells are supported<br />
by three steel “I” beams running the entire length of the units. In Option B, the two cells are supported by<br />
two steel “I” beams running across the width of the cells. Option B matches the typical crossflow supporting steel<br />
arrangement. This flexibility enables <strong>REP</strong> units to sit on the existing structural steel for most replacement projects,<br />
thereby resulting in lower installation costs.<br />

Operating Weight Savings<br />
The operating weight of <strong>REP</strong> units are approximately 35% less than conventional crossflow cooling towers. Due to<br />
the <strong>REP</strong> basin design and smaller plan area, less water is held in the unit during normal operation. Therefore, the<br />
structural support costs are reduced, and it is possible to locate the <strong>REP</strong> on a lighter roof, providing greater location<br />
flexibility.<br />

LOW OPERATING COSTS - OWNER SAVINGS<br />
Horsepower Savings<br />
The fan motor horsepower of <strong>REP</strong> Cooling Towers is typically equal to or less than other manufacturers’ fan motor<br />
horsepower. Reduced horsepower selections can save thousands of dollars in energy costs per year.<br />
The two cell <strong>REP</strong>’s have two fan motors, thereby providing mechanical redundancy and multiple steps of capacity<br />
control. For additional energy savings, two speed motors are recommended.<br />
When replacing centrifugal fan cooling towers, <strong>REP</strong> units will typically reduce the horsepower by as much as 50%.<br />
Maintenance Savings<br />
<strong>REP</strong> units have the most serviceable cold water basin in the industry. Removal of the light-weight inlet louvers provides<br />
easy access to all four sides of the basin for maintenance.<br />
Access to the fan and water distribution system is from the side of the unit. Routine maintenance can be safely<br />
performed by standing on the EVAPCO fill, which acts as a working platform.<br />
Totally enclosed fan motors are positioned for external access. Belt tensioning is performed from the outside of<br />
the unit. Bearing lube lines are also extended to the outside of the unit for easy service.<br />
Maintenance on <strong>REP</strong> towers is simple and easy. Maintenance costs are kept to a minimum.<br />
Water & Chemical Savings<br />
The stair step design of the <strong>REP</strong> pan basin significantly reduces the water volume in the unit (up to 35%) compared<br />
to crossflow equipment.<br />
The drift rate for <strong>REP</strong> Towers is less than .001% of the recirculated water rate. The typical crossflow drift rate is<br />
.005%. For a 500 ton tower, EVAPCO’s annual water savings from drift alone is 14,976 gallons. Also, the two pass<br />
inlet louver design eliminates splashout and water loss.<br />
The induced draft counterflow <strong>REP</strong> design with the two pass inlet louvers block direct sunlight from entering the<br />
unit, thereby reducing the potential for algae formation and reducing chemical costs.<br />
Exclusive Five Year Warranty<br />
All EVAPCO <strong>REP</strong> units come with a standard five year motor and drive warranty. Included<br />
are all drive components on belt and gear drive units. This unique warranty is designed to<br />
offer the end user optimum protection against fan drive and motor failure. <strong>REP</strong> units with<br />
stainless steel construction also have an exclusive Five Year complete product warranty.<br />

APPLICATIONS<br />
System Design<br />
<strong>REP</strong> Cooling Towers are constructed of heavy duty materials<br />
and are designed for superior performance providing<br />
long, trouble-free operation. However, proper equipment<br />
selection, installation and maintenance is necessary<br />
to ensure optimum unit performance. Several of the<br />
major considerations when designing and operating a<br />
cooling tower installation are presented in the following<br />
paragraphs. For additional information, contact your<br />
local EVAPCO representative.<br />
Air Circulation<br />
The location of a cooling tower is an important consideration<br />
when reviewing system design. Since cooling towers<br />
consume large quantities of air, adequate spacing<br />
around the unit is necessary for it to perform properly.<br />
The best place to locate any cooling tower is on a roof or<br />
at ground level away from walls and other obstructions.<br />
Cooling towers that are located in wells, enclosures, or<br />
are adjacent to high walls must be properly located to<br />
avoid the effects of recirculation. Recirculation occurs<br />
when some of the hot moist discharge air leaving the<br />
cooling tower flows back into the fresh air inlet. When<br />
recirculation causes the inlet wet bulb temperature to the<br />
cooling tower to be increased, the capacity of the cooling<br />
tower is decreased. Refer to EVAPCO Bulletin 311,<br />
Equipment Layout Manual, for the recommended layout<br />
guidelines for cooling towers.<br />
Maintaining the Recirculated Water System<br />
A cooling tower removes heat by evaporating a portion<br />
of the recirculated spray water. As a general rule, a cooling<br />
tower evaporates 3 US GPM per 100 tons of cooling<br />
capacity. As this water evaporates, it leaves behind all of<br />
its mineral content and impurities. Therefore, it is important<br />
to bleed an amount equal to that which is evaporated<br />
to prevent the buildup of impurities. If this is not<br />
done, the mineral content in the water will increase until<br />
the solids eventually deposit in the unit, causing heavy<br />
scaling. The bleed line should be installed in the external<br />
piping of the unit. It must be properly sized for the<br />
application and be provided with a metering valve and<br />
flow measurement device to allow for field adjustment of<br />
the bleed rate.<br />
Water Treatment<br />
EVAPCO recommends that all cooling tower users should<br />
consult with a reputable water treatment company familiar<br />
with local water conditions in order to determine the<br />
extent and type of water treatment program recommended<br />
for each specific application. Any chemical<br />
water treatment used must be compatible with the galvanized<br />
construction of the unit. If acid is used for treatment,<br />
it should be accurately metered and the concentration<br />
properly controlled. The pH of the water should be<br />
maintained between 6.5 and 8.0. In order to prevent<br />
“white rust”, the galvanized steel in the unit may require<br />
routine passivation of the steel when the system is operating<br />
in the higher pH levels.<br />
Batch chemical feeding is not recommended because it<br />
does not afford the proper degree of control. If acid<br />
cleaning is required extreme caution must be exercised<br />
and only inhibited acids compatible with galvanized steel<br />
construction should be used. Consult EVAPCO’S<br />
Maintenance Bulletin 112 for additional information.<br />
Capacity Control<br />
The design wet bulb temperature for which a cooling<br />
tower is sized occurs only a small percentage of the time.<br />
Since the wet bulb temperature is lower than design<br />
much of the time, and cooling loads tend to fluctuate,<br />
some form of capacity control will be required. The simplest<br />
form of capacity control is to cycle the fans on and<br />
off. However, this type of control results in larger temperature<br />
differentials and does not provide close control<br />
of the leaving water temperature.<br />
A better method of capacity control is to use two speed<br />
fan motors, which add a second step of control. Two<br />
speed motors are an excellent method of capacity control<br />
for the <strong>REP</strong> Cooling Tower. This arrangement gives<br />
capacity steps of 10% (fans off), 60% (Fans at half speed)<br />
and 100%. A temperature controller can be supplied to<br />
set control at 5& F increments, so that close temperature<br />
control can be maintained without excessive cycling of<br />
the fan motor.<br />
Two speed motors also reduce operating costs. At half<br />
speed, the motor draws approximately 15% of the full<br />
load power. Since the maximum wet bulb temperature<br />
and maximum load very seldom coincide, the cooling<br />
tower will actually operate at half speed about 80% of<br />
the time. Therefore, power costs will be reduced by 85%<br />
during the major portion of the year.<br />
A third advantage of two speed motors is that noise levels<br />
are reduced by approximately 6 dB when operating at<br />
half speed. Since both the load and wet bulb temperature<br />
are normally lower at night, the sound generated by<br />
the cooling tower will be substantially reduced during<br />
the most noise sensitive time period.<br />
For multiple cell units, both fan cycling and two speed<br />
motors can be used to provide additional steps of control.<br />
The combination of fan cycling and two speed motors<br />
offers a simple and inexpensive means of controlling unit<br />
capacity along with substantially reducing the energy<br />
costs of the cooling tower.<br />
Piping<br />
Cooling tower piping should be designed and installed in<br />
accordance with generally accepted engineering practices.<br />
All piping should be supported by properly designing<br />
hangers and supports with allowances made for possible<br />
expansion and contraction of the piping system. No<br />
external loads should be placed on the cooling tower<br />
connections. Do NOT anchor any of the piping supports<br />
to the cooling tower or its framework.<br />
Control of Biological Contamination<br />
Water quality should be checked regularly for biological<br />
contamination. If biological contamination is detected, a<br />
more aggressive water treatment and mechanical cleaning<br />
program should be undertaken. The water treatment<br />
program should be performed by a qualified water treatment<br />
company. It is important that all internal surfaces<br />
be kept clean of accumulated dirt and sludge. In addition,<br />
the drift eliminators should be checked periodically<br />
to ensure that they are clean and have not been damaged.<br />
Note: The location of the cooling tower must be considered<br />
during the equipment layout stages of a project. It<br />
is important to prevent the discharge air (potential of<br />
biological contamination) from being introduced into the<br />
fresh air intakes of the building.<br />

APPLICATIONS<br />
Special Applications of the <strong>REP</strong> Cooling Tower<br />
The <strong>REP</strong> Cooling Tower is designed for all air conditioning and industrial cooling applications. There are some design<br />
situations where special consideration must be given for the type and size of unit selected, such as, materials of construction,<br />
thermal performance, water quality, unit layout and local fire codes. Some of these special applications are<br />
described below.<br />
Freecooling<br />
Freecooling allows chilled water to be produced by the<br />
cooling tower without the use of a mechanical chiller<br />
during low ambient conditions. The freecooling or<br />
economizer mode of an air conditioning system is used<br />
to save $/KWH when the conditions allow the water in<br />
the tower to be cooled to “chiller” like temperatures,<br />
typically 42-45F LWT.<br />
EVAPCO’s counterflow cooling towers are well suited for<br />
free cooling applications. The counterflow fill design<br />
helps prevent ice formation with its even temperature<br />
gradient through the fill section and enclosed location<br />
blocking it from the elements. However, special caution<br />
must be taken when selecting, sizing and operating a<br />
cooling tower during normal winter or severe winter<br />
applications.<br />
Please consult EVAPCO’s Engineering Bulletin on Free<br />
Cooling Operation of Open Cooling Towers to assist in<br />
selecting a tower for a freecooling application.<br />
High Temperature Applications<br />
EVAPCO’s <strong>REP</strong> Cooling Tower as standard is capable of<br />
handling up to 130°F entering water temperature, which<br />
is higher than most crossflow cooling tower fill sheets. It<br />
will not deform or degrade at a continuous temperature<br />
application of 130°F.<br />
However, there are applications where a higher temperature<br />

Rigging Guidelines<br />
The rigging requirements of the <strong>REP</strong> Cooling Tower are<br />
covered in EVAPCO’s Rigging Bulletins which are available<br />
from your local EVAPCO Representative or the factory.<br />
Consult Bulletin# 148.<br />
These guidelines cover recommended lifting methods for<br />
the top and bottom sections of the cooling tower and<br />
how to mate the sections together. In addition, installation<br />
instructions for the flume box, flume plate, vertical<br />
& horizontal splash guards (multi-cell units only) fan<br />
screens and motor/gearbox davits are also provided.<br />

Dirty Water Applications<br />
The EVAPAK ® fill used in the <strong>REP</strong> Cooling Tower is<br />
designed to operate in almost all cooling water applications.<br />
However, there are some “dirty” water applications<br />
where the standard fill spacing is not adequate,<br />
such as a pulp and paper mill cooling tower or other<br />
application where heavy particulate will be mixed in<br />
with the water.<br />
Please consult the factory for a special cooling tower<br />
selection (for this application) utilizing EVAPCO’s<br />
exclusive EF19 and EVF 19 anti-fouling fill.<br />
