Semi-hermetic frequency-controlled
The CSV series is optimised for maximum efficiency in liquid chillers and heat pumps with frequency-controlled capacity adjustment. The internal frequency inverter enables a large spectrum of applications and a broad range of control, which simplifies system integration. The CSV series also accommodates all the IQ functions.

CSV.2 & CSV.3 SERIES
The CSV is the BITZER compact screw compressor series with integrated frequency inverter for best-in-class seasonal efficiency. The built-in frequency inverter makes it possible to achieve a very accurate system temperature and load profile by means of a very wide capacity modulation range. By integrating the frequency inverter and IQ functionality in the compressor, the CSV offers a new level of compactness and user-friendliness. This simplifies the system integration and enables a compact and cost-effective system design.
