<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.

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 />

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 />

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.”

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 />

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 />
