CoolTeg Plus CW

CoolTeg Plus CW

Units are connected to the chilled water distribution system in the data centers. This may be a modular cooling system with unlimited capacity. Everything depends on the proper design and implementation of the piping, pumps and chillers.


  • Unlimited number of units connectible to any single water system
  • Free-cooling system conserves ample amounts of energy
  • Variable chiller types fulfill any requirements (outdoor noise level, extreme ambient temperatures, etc.)
  • Water temperatures variable during the year, conserving energy while controling humidity levels
  • Maintains water temperature between 6 °C and 30 °C


In our CoolTeg Plus air-conditioning units we use a combination of the newest technologies and precision controls based on our experience and feedback from data centers around the world. Since fans, heat exchangers and control parts are becoming more advanced, we have modified our products to make sure our clients get the best and latest features.

We started producing a new generation of CoolTeg Plus units with energy-efficient fans that use EC technology as well as high-efficiency copper-aluminium heat exchangers. We can now measure the humidity and temperature in both the cold and hot zones. The unit's air intake and blowing areas were also enlarged for to ensure perfect air distribution.

The main difference is most noticeable in the unit's control part. We are now using an absolutely new controller with advanced Conteg software as well as a new 4.3” graphic touchscreen resistive display with 65,000 colors that corresponds with the latest technology. One display can be used for all CoolTeg units in one data room – up to 30 units with a maximum distance of 500m. Communication through TCP/IP protocol and integrated web server is standard, and remote control from any computer connected to the Internet is simply manageable.

CoolTeg Plus is basic part of the Conteg's new generation of Targeted Cooling solutions for all projects in modern data centers.

The temperature of the chilled water may be from +4 ° C to virtually unlimited levels. Lower water temperature will improve the cooling performance of CoolTeg units. Higher water temperatures can significantly reduce the cooling system's overall energy consumption.  Each unit's cooling capacity can be changed by the position of a three-way valve. Changes in the fan speed can help attain a constant temperature distribution in cold and hot zones in a data center's cold and hot zones. When it is necessary to reduce the relative humidity to the set point, the unit automatically responds by decreasing the flow of air and opening the water valve. CoolTeg CW units provide you with top-quality performance, while at the same time reducing your annual energy consumption levels better than any other air conditioning unit on the market today.

CoolTeg Plus CW units are suitable for cooling systems with free-cooling. If you use them in conjunction with EC technology fans, you will be able to further reduce your annual energy consumption.

1 CoolTeg units can be used either independently (in rack rows) or integrated in Modular Closed Loop (MCL) – closed architecture rack systems and cooling units;Code changed as per ordering matrix

2 Cooling capacity is changed by controller; nominal cooling capacity is calculated at return hot air temperature of 35 °C without condensation (air humidity belowdew-point), chilled water temp. 6/12 °C (for CW)

3 Net cooling capacity is the cooling capacity minus fan heat load - the actual unit cooling capacity available to IT equipment

4 Airflow is changed by the controller; nominal airflow matches nominal cooling capacity
