Omega Sky & Omega Sky FC/NG versions The new Omega Sky series of internally installed cold water generators and heat pumps with screw compressors was developed with special regard to changing coolant situations and rising efficiency requirements of Ecodesign directives. This device series meets the requirements of Ecodesign directive 2281/2016. All models with R513A or R134a are EUROVENTcertified. The performance range is from 430 to just under 1,600 kW cooling capacity. Depending on requirements, 1–2 infinitely variable standard or speed-controlled screw compressors are fitted. Omega Sky...

The free-cooling function units meet the rising demand for energy saving: they were developed in order to reduce operating costs of cooling machines which, for longer or shorter periods throughout the year, run with low ambient temperatures. The strength of the Omega Sky FC/NG with free-cooling function lies in its control system. Outside air can be utilized as a free resource, thereby substantially reducing the amount of energy required by the compression system. Focusing on energy saving, the control unit activates the appropriate operating mode on the basis of temperature probe readings...

Operating modes Summer operation (100 % mechanical cooling) In exclusively mechanical cooling mode, because outside temperatures are too high to start free cooling, Omega Sky FC/NG operates like a normal cold-water generator. The 3-way valve is fully open to the condenser but fully closed to the free-cooling plate heat exchanger. Should a condensing pressure control be required at this stage, this task is performed by the frequency converter for the cooling water pump. Path A-AB of the 3-way valve is open. The recooler operates in recooling mode, and the nominal value is 35°C. Combined...

Compact design Easy fitting and high-performance installation In addition to its energy efficiency, Omega Sky also has a highly compact design. Unit sizes with semi-hermetic screw compressor have a maximum depth of 900mm and a height of 1,983mm (max. cooling capacity approx. 800 kW). For existing buildings, this allows fitting through standard door sizes. A connection via flange is optionally available (Standard Victaulic). For units with two cooling circuits a ready-made, prefabricated tube connection for the two tube-bundle heat exchangers is optionally available.
