<strong>Chillers</strong>, <strong>air</strong> <strong>and</strong> <strong>water</strong> <strong>cooled</strong>, <strong>featuring</strong><br />

<strong>centrifugal</strong> compressors with magnetic<br />

levitation, from 200 to 1.949 kW


2 l 3


Today's office buildings, hotels, large shopping <strong>and</strong><br />

leisure complexes, all the most prestigious projects<br />

require leading edge solutions to meet extremely<br />

dem<strong>and</strong>ing challenges:<br />

Very strict energy efficiency <strong>and</strong><br />

sustainability requirements<br />

Reduced initial investment <strong>and</strong> running costs, compliance with<br />

increasingly strict energy consumption <strong>and</strong> environmental impact<br />

regulations, are becoming more <strong>and</strong> more crucial factors not only for real<br />

estate valuation, but also in deciding if the project should proceed.<br />

Precise attention to comfort <strong>and</strong> noise<br />

emissions<br />

To guarantee ideal temperature, humidity <strong>and</strong> <strong>air</strong> quality goes together<br />

with the need to reduce noise emissions <strong>and</strong> vibrations. This is a decisive<br />

aspect in order to ensure adequate comfort, as well as to comply with<br />

noise emission regulations.<br />

Complex architecture <strong>and</strong> logistics<br />

The search for prestigious central locations together with regulations <strong>and</strong><br />

incentives for requalification of urban areas increase the building site<br />

logistical complexity <strong>and</strong> the challenge of moving the system’s<br />

components.<br />

Infrastructure <strong>and</strong> technical space<br />

optimization<br />

The real estate value, especially with expensive, prestigious investment in<br />

urban environments may be determined also by the quality of the<br />

electrical system installed. Hence, choices that do not overload electrical<br />

infrastructure are more <strong>and</strong> more desirable.


4 l 5<br />

Resulting from <strong>Climaveneta</strong>’s experience in utilizing<br />

magnetic levitation technology in <strong>air</strong>-conditioning <strong>and</strong><br />

process cooling industries, TECS Vision 2.0 <strong>air</strong> <strong>and</strong><br />

<strong>water</strong> source chillers are the most efficient <strong>and</strong> reliable<br />

solution available in the market today.


ESEER 9,52 for TECS2-W with all the advantages in terms of<br />

reliability <strong>and</strong> technical support, due to <strong>Climaveneta</strong>’s unbeatable<br />

knowhow of this technology, for a truly ideal answer to the challenge<br />

of the most dem<strong>and</strong>ing applications:<br />

Ubeatable efficiency<br />

at part load<br />

At partial load, TECS units are far more efficient than traditional<br />

scroll/screw units, with ESEER values up to 60% higher.<br />

Running cost savings are evident <strong>and</strong> consistent, especially when all year<br />

round operation is required.<br />

Extremely silent operation<br />

Thanks to the adoption of the <strong>centrifugal</strong> compressor with magnetic<br />

levitation, <strong>and</strong>, in <strong>air</strong> source units, of fans with reduced noise emission,<br />

TECS sound power <strong>and</strong> pressure are the lowest on the market, without<br />

peaks in any of the sound frequency spectrum.<br />

Vibrations are dramatically reduced as well, with considerable advantages<br />

in terms of transmission to the building..<br />

Simplified logistics<br />

Turbocor compressors feature an extremely advantageous<br />

capacity / weight ratio.<br />

The considerable weight reduction allows simplified site operations.<br />

Moreover, for <strong>water</strong> source units this goes together with reduced<br />

dimensions, thus enabling also a reduction of plantroom space.<br />

Low in rush current<br />

A further benefit is the very low inrush current, obtained thanks to the<br />

characteristics of the compressor <strong>and</strong> to the “inverter” starting. This is a<br />

crucial factor, as it allows a more favourable selection of the protection<br />

devices to be placed on the power supply between transformer <strong>and</strong> unit.

Centrifugal compressor with<br />

magnetic levitation<br />

This is a miniaturized, highly innovative compressor, with<br />

magnetic levitation device <strong>and</strong> digital control of the rotor’s<br />

speed. The efficiencies achieved are far superior to those with<br />

traditional volumetric compressors.<br />

Inverter controls with inlet guide vanes extend the<br />

compressor’s operational limit: building requirements are<br />

precisely met, even at very low conditions.<br />

A solution that, besides the reduction of weight <strong>and</strong> dimensions<br />

with respect to traditional compressors, permits the<br />

compressor to operate completely without oil allowing an<br />

improvement of its performance, through the heat exchange<br />

process. Vibrations are virtually eliminated together with<br />

possible jolts due to inrush current in the start up phase: the<br />

unit’s wear is minimized.<br />

EC Fans<br />

On TECS2 units, the technology of EC electronic switching<br />

fans is introduced, as st<strong>and</strong>ard on SL-CA-E versions <strong>and</strong><br />

optional on the other models.<br />

The superior energy efficiency of the DC brushless motor<br />

further improves the chiller’s performance, that reaches the<br />

highest ESEER level in the market.<br />

More advantages are low inrush current <strong>and</strong> the ability to<br />

continuously modulate the rotational speed with an<br />

immediate gain in both silence <strong>and</strong> energy consumption.


Efficiency, silent operation <strong>and</strong> reliability. And also compact<br />

dimensions <strong>and</strong> reduced weight. These are the main<br />

features that make TECS units the best result of<br />

<strong>Climaveneta</strong>’s know-how. Advantages that result from<br />

technological choices, involving each aspect of these units.<br />

Flooded evaporator<br />

The technology of flooded evaporator, further enhanced<br />

the absence of oil in the refrigerant circuits, realises a<br />

substantial increase of cooling capacity <strong>and</strong> an optimization in<br />

the compressor’s operational mode. The unit’s overall<br />

efficiency further increases thanks to:<br />

compression ratio reduction thanks to a smaller approach<br />

theoretic absence of refrigerant superheat at the<br />

compressor’s suction stage<br />

minimization of refrigerant pressure drop on the<br />

evaporator’s shell side<br />

optimization of the exchange surfaces, also at part loads,<br />

thanks to the complete control of the refrigerant level in all<br />

operating conditions.<br />

To comply with the security requirements of the “F-gas<br />

Regulation” (CE 842//2006), factory calibrated leak detection<br />

systems are available upon request.<br />

Electronic valve<br />

The electronic valve is adopted to grant the ideal operation of<br />

the evaporator in all conditions.<br />

In the <strong>water</strong> <strong>cooled</strong> unit TECS2-W, the complete flooding of<br />

tubes is granted with a sophisticated detection of the<br />

refrigerant level in the heat exchangers, while in the <strong>air</strong> <strong>cooled</strong><br />

unit the control is made with a precise measurement of the<br />

subcooling in the condenser coil.<br />

The fast processing of the acquired data allow a quick,<br />

fluctuation-free regulation, <strong>and</strong> therefore a highly accurate<br />

adjustment to the swings of load <strong>and</strong> ambient conditions.

product development the Vision 2.0 has<br />

been conceived. The capacity range is now<br />

extended up to 1.325 kW, with 26 sizes<br />

<strong>featuring</strong> unbeatable efficiencies <strong>and</strong> noise<br />

levels.<br />

Oasis cooling kit. The perfect solution for<br />

<strong>air</strong>-conditioning beyond the units' operating limits.<br />

Especially in harsh climates, with requirements of prolonged operation<br />

at high ambient <strong>air</strong> temperatures, units can benefit from devices<br />

offering additional cooling whenever outdoor conditions become critical.<br />

The ideal solution in these situations is<br />

to lower the condenser coil entering <strong>air</strong><br />

temperature when it becomes too<br />

high, causing the condensing<br />

temperature to go over the<br />

compressors operating limits. This is<br />

obtained by <strong>Climaveneta</strong> with the<br />

Oasis kit option.<br />

d<br />

Air <strong>cooled</strong> units<br />

TECS2 units are available in 2 functions:<br />

base <strong>and</strong> with desuperheater, for<br />

applications in which thermal energy is<br />

used for auxiliary uses,<br />

<strong>and</strong> in 2 acoustic versions:<br />

SL-CA, Super Low Noise, Class A<br />

<strong>and</strong> XL-CA, eXtra Low Noise, Class A<br />

to satisfy even the most dem<strong>and</strong>ing<br />

noise level targets.<br />

High efficiency versions SL-CA-E are<br />

available, for an even higher efficiency<br />

thanks to the adoption of EC fans <strong>and</strong> to<br />

generous heat exchanger surfaces.<br />

How the Oasis kit works<br />

When the condensing conditions reach a pre-defined set point, the<br />

controller open a solenoid valve <strong>and</strong> <strong>water</strong> is sprayed over a plastic<br />

net. The contact between the <strong>air</strong>flow forced through the wet plastic<br />

net, reduces the condenser coil inlet <strong>air</strong> temperature. This allows:<br />

1 A further extension of the<br />

operating limits by 5-6°C,<br />

depending on the relative<br />

humidity.<br />

2 A benefit for the silenced version<br />

(because the high condensing<br />

control can be postponed to<br />

higher temperature).<br />

3 Increased efficiency of the unit<br />

when the system is active.

Water <strong>cooled</strong> units<br />

TECS2-W units are available in 2 functions:<br />

base <strong>and</strong> H, heat pump reversible on<br />

hydraulic side<br />

<strong>and</strong> in 2 versions:<br />

LC, Low Condensing. For applications in<br />

which the <strong>water</strong> <strong>cooled</strong> unit is coupled<br />

with medium temperature external source,<br />

for example groundsource or cooling<br />

towers<br />

HC, High Condensing. For application in<br />

which the unit is expected to work at high<br />

condensing levels, as for example in some<br />

critical dry-cooler installations or in all<br />

situations in which reversibility in heat pump<br />

mode is requested.<br />

<strong>Climaveneta</strong>'s system advantages vs traditional solutions<br />

The <strong>Climaveneta</strong> Oasis solution offers many advantages even if compared to<br />

systems with pressurized atomizers which spray <strong>water</strong> directly to the coil:<br />

No dedicated pumps: the <strong>water</strong> is taken direktly from tap <strong>water</strong>.<br />

No limescale on the coil: the <strong>water</strong> is sprayed toward the plastic net, <strong>and</strong><br />

not toward the coil.<br />

Easy application - it's possible to use common supply <strong>water</strong>, no need for<br />

special <strong>water</strong> treatment.<br />

Minimized risk of bacterial population increase: recirculated <strong>water</strong> loop<br />

does not exist; <strong>water</strong> immediately evaporates when sprayed on the net.<br />

Optimal control of <strong>water</strong> consumption: thanks to effective spray<br />

regulation.

Oasis kit performance<br />

The table on the right shows the effects of Oasis kit in relation to outside <strong>air</strong> temperature <strong>and</strong> relative humidity.<br />

It is clear that, the higher the <strong>air</strong> temperature <strong>and</strong> lower the <strong>air</strong> humidity, the higher the system’s effectiveness: in these<br />

conditions infact, as higher <strong>water</strong>flow is sprayed to the net, <strong>and</strong> most of it evaporate thanks to the energy given by the<br />

<strong>air</strong>flow through the net, <strong>water</strong> evaporates <strong>and</strong> <strong>air</strong> is <strong>cooled</strong>.<br />

Water consumption comparison.<br />

Another point to highlight is the<br />

<strong>water</strong> consumption, which is less<br />

than 30% of that requested by a<br />

cooling tower coupled to a <strong>water</strong><br />

<strong>cooled</strong> unit of the same cooling<br />

capacity.<br />

Willis Building<br />

Project<br />

The latest striking addition to the London sky-line is the iconic Willis building.<br />

Designed by Foster <strong>and</strong> Partners, it is the City of London’s fourth highest skyscraper<br />

<strong>and</strong> will provide high quality contemporary office accommodation for Willis Group, the<br />

world's third largest insurance broker.<br />

Challenge<br />

This masterpiece of architecture comprising two adjoining structures of 10 <strong>and</strong> 28<br />

storeys has already achieved an excellent environmental assessment award, with a<br />

10 out of 10 BREEAM rating.<br />

To achieve this st<strong>and</strong>ard required an <strong>air</strong> conditioning system designed to the most<br />

stringent requirements. The system, besides ensuring highest energy efficiency, also<br />

ensures lowest noise emissions, compact sizing of transformer <strong>and</strong> power supply,<br />

<strong>and</strong> the most favourable selection of the protection devices between these devices<br />

<strong>and</strong> the unit.<br />

Solution<br />

For the consulting engineer, RPP, the most suitable choice was based on compact<br />

TECS mini <strong>centrifugal</strong> <strong>air</strong> <strong>cooled</strong> chillers, 5 for the Tower <strong>and</strong> 2 for the adjoining<br />

Fenchurch Avenue Building. They allow simplified logistics, unbeatable energy<br />

efficiency at part loads, lowest inrush current <strong>and</strong> extremely quiet operation.<br />

Hydronic fan coils in the false ceilings ensure optimum comfort conditions with<br />

minimal aesthetic impact to the office interiors.<br />

Twickenham Stadium<br />

ect<br />

oric <strong>and</strong> iconic world class rugby stadium <strong>and</strong> now also a top concert venue <strong>and</strong> a leading<br />

eisure <strong>and</strong> business destination, Twickenham Stadium is the home of Engl<strong>and</strong> Rugby<br />

l Union <strong>and</strong> the largest rugby stadium in the world, with a capacity of 82,000 seats.<br />

allenge<br />

cent South St<strong>and</strong> redevelopment, completed by the beginning of the Stadium’s 100th<br />

, comprises 25 conference rooms, 4 suites of various capacities up to 800 seats <strong>and</strong> a<br />

ar hotel, offering integrated conference <strong>and</strong> exhibition space, 365 days a year. All these<br />

s required an <strong>air</strong> conditioning solution providing perfect comfort with highest possible<br />

selected 7 <strong>Climaveneta</strong> super compact TECS <strong>air</strong> <strong>cooled</strong> chillers. Featuring highest part load<br />

efficiency <strong>and</strong> extremely silent operation, they achieve excellent energy <strong>and</strong> operational cost<br />

savings. Moreover the very low noise emissions, extremely low starting current <strong>and</strong> compact<br />

size of the units proved to be the ideal choice, assuring simplified logistics <strong>and</strong> extremely silent<br />

operation.<br />

The consultant's opinion<br />

London - United Kingdom<br />

2006 - 2009<br />

Designed by:<br />

Ward McHugh<br />

Mr. A Centola<br />

“<strong>Climaveneta</strong> chillers provided the necessary energy <strong>and</strong> acoustic performance. At the same<br />

time the Company has an enviable reputation for efficiency <strong>and</strong> reliability <strong>and</strong> the widest<br />

experience in sport applications <strong>and</strong> in the use of magnetic levitation technology. Having<br />

already carried out many successful projects with them, we had no hesitation to select them<br />

also for the Twickenham Stadium.”


Abbey (Sant<strong>and</strong>er) Bank<br />

Project<br />

In 2007 Abbey (Sant<strong>and</strong>er) Bank launched an ambitious programme to replace existing old <strong>and</strong><br />

expensive-to-run chillers with more efficient units. A project aimed to reduce expenses as well<br />

as assisting the environmental impact of the financial group operations through increased energy<br />

savings for its <strong>air</strong>-conditioning systems.<br />

Challenge<br />

Involving the replacement of a large amount of units over several years, the selection of the new<br />

units meant not only efficiency <strong>and</strong> robustness of the solution, but also reliability of the partner<br />

<strong>and</strong> quality of service. Given the great variety of installations <strong>and</strong> systems, also the range<br />

extension <strong>and</strong> the flexibility of the offer were crucial in order to approach the project in a rational<br />

<strong>and</strong> effective way.<br />

Solution<br />

After thorough examination of a number of alternatives, Abbey consultants chose <strong>Climaveneta</strong><br />

TECS units for all projects where chillers over 350kW were required. Utilising compressors with<br />

magnetic levitation, these units guarantee highest efficiency, without equal compared with any<br />

other technology. On the other h<strong>and</strong> <strong>Climaveneta</strong> expertise with TECS chillers, proven by over<br />

500 units installed all over the world was the best guarantee of the robustness required. Air <strong>and</strong><br />

<strong>water</strong> source, ranging from 200 to 2000kW, these units ensured an ideal flexibility, enhanced<br />

also by their compact dimensions. Numbers are the best proof of these advantages, with 13<br />

units installed since 2007 for more than 10.000kW total capacity.<br />

The consultant’s opinion<br />

Leading UK financial<br />

services company<br />

with 1300 branches<br />

in the whole country<br />

Mr. John Samson<br />

“When we analysed the available solutions, Powermaster - <strong>Climaveneta</strong> distributor for the U.K.-<br />

invited us to compare TECS units performance with those of traditional screw chillers. Results<br />

were striking. This, together with the reliability ensured by <strong>Climaveneta</strong>'s experience with these<br />

units <strong>and</strong> by the high quality service performed by Powermaster, left us in no doubt about<br />

choosing them as partners for this project.”

IKEA Rimini store<br />

Studio Tecnico Impianti<br />

Ing. Sergio Giuseppini<br />

Project<br />

Care for environment <strong>and</strong> sustainability are among IKEA core values. The desire to minimise the<br />

carbon footprint throughout the whole value chain is reflected also by the continuous research of<br />

high efficiency innovative solutions for its stores.<br />

Challenge<br />

Envisioned by an uncompromised approach to energy efficiency <strong>and</strong> sustainability achieved by<br />

blending cutting edge technologies <strong>and</strong> renewable resources in an unprecedented system<br />

solution, the <strong>air</strong> conditioning <strong>and</strong> heating system of the Rimini IKEA store has been, since the<br />

very beginning, a point of reference both for retail solutions <strong>and</strong> for the <strong>air</strong> conditioning systems.<br />

This geothermal application couples <strong>water</strong> <strong>cooled</strong> units with a ground source system. It meets<br />

the difficult challenge of sizing geothermal probes in order to optimize <strong>and</strong> balance the heat<br />

exchange both during winter <strong>and</strong> summer mode, employing at the same time the best<br />

performing units on the market in order to maximize global performances both in heating <strong>and</strong><br />

cooling mode.<br />

Solution<br />

For the building services engineer of the IKEA Group, Mr. Giuseppini, to choose <strong>Climaveneta</strong> as a<br />

partner was the first step in order to guarantee the success of this project. The system is based<br />

on 2 high efficiency <strong>water</strong> <strong>cooled</strong> reversible TECS units.<br />

Utilizing geothermal probes to absorb heat during winter <strong>and</strong> reject it during summer, the<br />

operating conditions are always optimized <strong>and</strong> the TECS efficiency is at its peak with EER up to<br />

15,0. The energy saving is further enhanced thanks to the variable flow pumps precise<br />

management, which has been integrated into <strong>Climaveneta</strong>’s solution.<br />

The consultant's opinion<br />

Rimini - Italy<br />

technology in units providing both heating <strong>and</strong> cooling within a very complex system.<br />

<strong>Climaveneta</strong> has been the ideal partner, both for its expertise with these applications as well as<br />

for the unchallenged capability to develop custom made solutions <strong>and</strong> for the high pre <strong>and</strong> after<br />

sales service level provided.”


Kings Place<br />

Project<br />

Designed by architects Dixon-Jones, Kings Place brings together in an iconic environmentally<br />

sustainable mixed-use building a major arts venue hub, elegantly situated bars <strong>and</strong> dining areas,<br />

an excellent conference <strong>and</strong> events centre, <strong>and</strong> a Grade A office complex.<br />

Challenge<br />

Being the first modern recital hall built in London, Kings Place was featured by extremely difficult<br />

design challenges. As a major concert <strong>and</strong> music hub, it required perfect noise insulation both<br />

from outside as well as between different halls, <strong>and</strong> perfect acoustics inside each room.<br />

Building regulations limited at 7 storeys the height of the building, thus imposing great focus on<br />

space optimization, to be combined with highest sustainability <strong>and</strong> refined aesthetics. These<br />

challenges were reflected by extremely dem<strong>and</strong>ing <strong>air</strong> conditioning requirements.<br />

Solution<br />

<strong>Climaveneta</strong> super low noise <strong>water</strong> <strong>cooled</strong> TECS chillers were the ideal solution for Arup<br />

Consultants in charge of the project. Their compact dimensions perfectly suited the installation<br />

requirements <strong>and</strong> their high efficiency strongly contributed to enhance the BREEAM rating of the<br />

building. The noise levels of the mini <strong>centrifugal</strong> compressors with magnetic levitations, together<br />

with the extended <strong>Climaveneta</strong> experience in theatre applications, assured perfect comfort with<br />

no compromises on the acoustics.<br />

The consultant's opinion<br />

London - United Kingdom<br />

2005 - 2008<br />

Designed by:<br />

Dixon Jones<br />

Mr. Nick Merridew<br />

“Technical systems were crucial for this project's success. We knew that <strong>Climaveneta</strong> was able<br />

to ensure the reliable tailor-made solution we were looking for, thanks to their know-how in<br />

mastering magnetic levitation technology <strong>and</strong> their experience with theatres <strong>and</strong> concert halls.<br />

Moreover the extended factory witness testing after unit manufacture <strong>and</strong> thorough pre <strong>and</strong> after<br />

sales support they offer, have been of great help in identifying the ideal solution for this<br />

complex.”
