Screw Compressor CSVW - CSVW37-240Y
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.
- Highly efficient rotor profile
- Oil management system of the third generation
- Automatic Vi control
- Seamless capacity control thanks to frequency inverters
- Ideal for systems that frequently operate under part-load – optimised to achieve even greater seasonal energy efficiency (ESEER/IPLV and SCOP values)
- Shortest length and lowest weight in its performance class
