Compressor specialist Bitzer showcased its new compact screw compressors which meet the European standards for liquid chillers.
The new BITZER CSH.6 series is designed for highly efficient air-cooled liquid chillers suitable for operation with R134a or the HFO/HFC blends R513A and R450A as well as the HFO refrigerants R1234yf and R1234z(E).
The compressor specialist is expanding its service range in the field of compact screw compressors: as a variation of the proven CSH.5 models, the CSH.6 series is designed for use with low-GWP refrigerants and optimised for the ambient temperature profile specified by the Ecodesign Directive for liquid chillers.
It boasts exceptional refrigerating performance and impressive seasonal energy efficiency ratios (SEER), helping OEMs to comply with legal requirements.
The application limit of the CSH.6 series is tailored to air-cooled liquid chillers for comfort air-conditioning and is characterised by adjusted oil management, economiser operation in full-load and specially adapted Vi in part-load operation, according to Bitzer's product manager for screw compressors, Dirk Schlehuber.
"We've developed the CSH.6 specifically for applications with air-cooled liquid chillers for air-conditioning applications, which have been subject to stringent requirements in terms of minimum energy performance in Europe since January," he said.
"The CSH.6 series allows our customers to continue building cost-effective liquid chillers which meet statutory (tier one) seasonal efficiency requirements without having to resort to costly use of frequency inverters."
