Screw Compressor VSK - VSK4151-20

The hermetic compact screws add to the screw compressor range in the lower capacity range. They are suitable for use in factory assembled air conditioning units, liquid chillers and especially for air conditioning in railway carriages. Thanks to the built-in oil reservoir and separation system, the compact design enables easy installation. With their thin design, low weight and smooth running over a wide range of speeds, the compressors meet the increasing requirements of confined roof and under-floor spaces.
