CSV.2 & CSV.3 SERIES

On the notepad

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 modulation range capacity. 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.
