CoolTeg Plus CW

Product introduction

CoolTeg Plus CW are the most modern units from the precision cooling family, suitable for efficient cooling of server rooms and data centers of all types. Water-cooled units are connected to a chilled water distribution system, which is usually shared by all units in the data center. This can create a cooling system with unlimited power and scale. It requires only an appropriate design and implementation of the pipe system, pumps and sources of cold - chillers. In our new CoolTeg Plus units, we leverage state-of-the-art technology and precise regulation based on our experience from data centers around the world. As the technology of fans, exchangers and control elements continues to evolve, we also innovate our products to ensure their best performance for our customers.

The units are equipped with power-efficient EC fans and an obliquely placed highly efficient heat exchanger. Temperature and humidity are measured in both the cold and warm zones, and the area for air intake and conditioned air exhaust has been maximized to optimize air distribution. The main differences can be found in the unit controller. We use a brand new type of controller with advanced CONTEG software and a new 4.3"" graphic color touch screen. One display can serve up to 30 air conditioning units in the data room with a maximum cable length of 500 m. The system communicates via the TCP/IP protocol, leverages an integrated web server and can be remotely controlled and supervised from a PC over the internet. The temperature of the cooling water must be +4 °C or higher without an upper limit. A lower water temperature will ensure a higher cooling performance of CoolTeg units, whereas a higher temperature can significantly reduce the overall energy consumption with modern sources of cold. The cooling capacity of each unit is individually adjusted according to the immediate requirements by the position of the three-way valve. Adjustment of the speed of the fans allows to achieve constant temperature distribution in the cold and hot zones of the data center. When it is necessary to reduce the relative humidity of the room to a preset level, the unit automatically responds by reducing the air flow and opening the water valve.

CoolTeg and CoolTeg Plus CW (chilled water) units deliver maximum sensible cooling capacity in relation to the latent cooling capacity thanks to advanced humidity management logic. Year-round energy consumption compared to other air conditioning units is therefore significantly lower. CoolTeg Plus CW units are perfectly suited for cooling systems with free cooling. Solutions with CoolTeg Plus units can be used for demanding uses cases, such as computing clusters, HPC (High Performance Computing), grids, bitcoin mining, etc.
