Centrifugal compressors

Centrifugal compressors feature a cast iron casing, a steel shaft and a cast aluminium alloy impeller.

The fluid is drawn in by the impeller near its axis and due to centrifugal force is pushed to the edge of the compressor casing. The fluid leaves the impeller with significant kinetic energy, which is then converted into pressure energy in the diffuser.
Use is limited to high cooling capacities and low compression ratios (usually large chillers running on R134A)
Cooling capacity can be varied using fins that change the angle at which fluid enters the impeller.

This category also includes compressors with magnetic levitation, featuring very high efficiency, complete absence of oil and vibrations, and control by inverter. The only downside is their extremely high cost.
