Omega Sky XEi FC / NG Version

The device version Omega Sky XEi FC / NG combines the constant power control of the screw compressor with a control system for sliding free cooling. With this system, it is possible to ensure very precise flow temperatures to the consumers. By means of the sliding free cooling, the operating costs of the system are greatly reduced. By

the use of outside air as refrigeration can be dispensed with the mechanical cooling at low outside tem- peratures. The integrated Blue Think® control determines the optimal use of the outside dry cooler, whether as a recooler or as a free-cooling heat exchanger. This reduces the use of screw compressors continuously. 

Free cooling pays off!

The units with free-cooling function meet the increasing energy saving need: they have been developed to reduce the operating costs of the chillers, which operate at low ambient temperatures for more or less long periods of the year.

The strength of the Omega Sky XEi FC / NG with free-cooling function lies in the control system. As a result, the free resource outdoor air can be used and thus the energy used by the compression system can be greatly reduced. With the focus on saving energy, the control system activates the ideal operating conditions based on the measurements of the outside air and the return temperature determined by the temperature probes.
