The compact CS series features mechanical capacity control, which enables very good efficiency and simple system integration. The finely graded models of the CS series are optimised for a large application range in liquid chillers and heat pumps. From CS.105 with IQ module.
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.
Efficient, robust, durable: thanks to the HSK/N version, HS semi-hermetic screw compressors are suitable for many application ranges and refrigerants. The internal capacity control is multistep and, from HS.85, stepless as an optional feature. All HS compressors are suitable for speed-controlled operation. From HS.95 with IQ MODULE.
HSK = Application for air-conditioning and medium temperature cooling
BITZER’s semi-hermetic HS screw compressors feature a built-in suction gas-cooled motor integrated into the refrigerant circuit. For many years, they’ve proven to be a robust and efficient market solution – on their own and in parallel operation with several compressors and a shared oil separator. Because they’re compatible with a variety of refrigerants and boast a wide range of capacities and applications, these compressors are the first choice for large-scale commercial and industrial applications. They’re used when larger refrigerating capacities are required, for instance in blast freezers for the food industry as well as in refrigerator and freezer distribution warehouses. HS compressors are also suitable for many other refrigeration and heat pump application.
The 2-stage reciprocating compressors are designed for an extensive application range and boast an optimised drive gear and efficient motor. The highly reliable semi-hermetic series is designed to be robust and suitable for a variety of refrigerants.
BITZER is raising the bar in terms of technology and capacity for expanded low temperature applications with the 2nd generation of 2-stage compressors. This series is the result of extensive research on the basis of years of experience in the construction of highly efficient and solid reciprocating compressors. The gas flow control and working valves are specially adapted for low temperature applications.
