Fluid-injected rotary screw compressors are used in a wide range of market and industry sectors. They are highly durable and operate reliably and efficiently even at high temperatures of up to 45 °C. The associated investment costs are comparatively low.
However, the lion‘s share of life-cycle costs is spent on energy (up to 80 %). In fact, energy costs taken over the lifetime of a compressor, add up to a multiple of investment costs. For this reason, HPC KAESER rotary screw compressors are equipped with energy-saving SIGMA profile airend rotors that save up to 15 % energy compared to conventional rotor profile designs plus the latest premium efficiency, energy saving electric motors.
