CoolTeg Plus DX
The CoolTeg Plus DX indoor unit with a Mitsubishi outdoor compressor unit is a highly effective system especially suitable for server rooms up to 100kW. The new generation is equipped with EC fans and touch.
Besides fans and regulation components, the indoor CoolTeg Plus DX units include the highly effective evaporator for refrigerant R410A. Each indoor unit must be connected with refrigerant pipes to the Mitsubishi outdoor compressor unit. The split system will then be able to control itself. The outdoor Mitsubishi units are equipped with frequency-controlled compressors, electronic expansion valves, and other components. They come in three capacities—7 kW, 12 kW and 18 kW (stepless regulation) in various versions. In our CoolTeg Plus DX 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 DX 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 center – up to 16 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 manageable. CoolTeg Plus DX indoor air-conditioning units are designed to be used with select Mitsubishi Electric outdoor high-end compressor units. CoolTeg Plus DX is a basic part of CONTEG's new generation of Targeted Cooling solutions for all projects in modern data centers.
The cooling system performance is limited by the distance between the indoor and outdoor units (see detailed technical documentation) and their height differences. Cooling operation is guaranteed at ambient temperatures ranging from -15 to +46 °C. Used in conjunction with the outdoor compressor unit, CoolTeg Plus DX is a highly effective system that comes with ecological refrigerant and is especially suitable for server rooms with a total capacity of up to 100 kW. When a higher cooling capacity is needed, water systems are probably more efficient. The cooling capacity of each unit can be changed, according to individual requirements, by opening the electronic expansion valve and by changing the compressor and the fan's speed (fans in the indoor and outdoor units). If it is necessary to reduce the relative humidity to the setpoint, the unit will automatically respond by reducing airflow and increasing the cooling performance. CoolTeg Plus DX units provide you with top-quality performance, while at the same time reducing your annual energy consumption levels better than any other direct expansion unit on the market today.

Width 300 mm, depth 1 000 mm or 1 200 mm, height from 42U (1 978 mm) to 48U (2 245 mm)
5 radial fans with high-performance EC motors
One indoor unit must be connected to one selected outdoor Mitsubishi Electric compressor unit
Cooling capacity depends on the outdoor unit (12 kW or 18 k W) (temperature of return air of 45 °C and SHR=100 %; ambient temperature +35 °C)
The electric power supply of the indoor unit is 230V/50Hz, for the outdoor unit see detailed technical information. The indoor unit can be powered through the outdoor unit or separately.
The momentary cooling capacity is adjusted by changing the speed of the compressor, indoor fans, and outdoor fans to keep the temperature set-points.
The minimal cooling capacity is about 30 % of the nominal one. In the long term, the heat load must reach at least 50 % of the nominal cooling capacity determined by the outdoor unit.
Communication via 4.3” color touchscreen display or through digital I/O connectors.
Display with an integrated web server can control up to 16 units in the group, with advanced functions (standby unit, overload start, etc.)
TCP/IP is standard and other protocols (Bacnet, Modbus, etc.) are available upon request.
Software upload and data download via USB flash memory disk.
