The new CSH series is based on the proven design elements of the innovative BITZER compact screws, which are recognized as a benchmark around the world. They were developed with respect to universal application in air cooled liquid chillers and heat pumps. Besides their known attributes, the compressors are distinguished by further improvements to energy efficiency under full- and part-load conditions. Additionally, the application limits were greatly expanded both in terms of low saturation discharge temperatures and high pressure ratios (heat pumps) – without compromising operating reliability
