CSVW series
The CSVW series is a unique new development in the field of compact screw compressors, specially developed for speed control and optimised for use in water cooled liquid chillers as well as in air cooled liquid chillers with low condensing temperature. The efficient, proven and reliable engineering of the CSW series and many years of experience with speed-controlled compressors form a sound foundation. The CSVW compressor series significantly simplifies the installation and safe use of speed-controlled compressors in air conditioning and process cooling, thanks to integrated frequency inverters, sensors for compressor protection and monitoring, and solenoid valves (Vi control and liquid injection) in a single prewired package.
