CoolTeg Plus CW - In-row Cooling | CONTEG

CoolTeg Plus CW

CoolTeg CW units are suitable for cooling systems with a chilled water source. They can be used with free-cooling systems. The new generation is equipped with EC fans and touch display.

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. In our CoolTeg Plus CW 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 CW units with energy-efficient fans that use EC technology as well as high-efficiency copper-aluminum 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 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 correspond 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 500 m. Communication through TCP/IP protocol and the integrated web server is standard, and remote control from any computer connected to the Internet is simple manageable. CoolTeg Plus CW is a basic part of 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 Plus CW 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 setpoint, the unit automatically responds by decreasing the flow of air and opening the water valve. CoolTeg Plus 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.


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