Bitzer Presents Reciprocating Compressors

There is a good reason why CO₂是选择超市的制冷剂应用cations. It is future-proof while offering high energy efficiency and low global warming potential. Another product is the 2-cylinder reciprocating compressor for transcritical CO₂applications from the CKH2 family. The exhibited 2KTE-7K belongs to a family of compressors extended by two further displacements, providing Bitzer with a well-matched and broadly spread spectrum of displacement volumes from 3.3 m³ to 38.2 m³/h (50 Hz). As for all models in the series, it can be controlled to run at speeds between 30 and 70 Hz and has been designed for the special requirements of the natural refrigerant CO₂. Thanks to their innovative cylinder heads, the entire series works with low pressure pulsation.

By using CO₂as a refrigerant, the operation of the reciprocating compressor, with a global warming potential of 1, is particularly environmentally compatible and it is ideally suited for smaller supermarket applications. The compressor is especially energy-efficient in combination with the Varipack external frequency inverter from Bitzer. With this, users can smoothly adjust a compressor’s capacity to meet the actual requirements and save energy. As Bitzer specially developed the frequency inverters for combination with its reciprocating compressors and for use in refrigeration, they are ideally matched to one another. This means that they are energy-efficient, reliable and their operation is intuitive.
