Oil-free Compressor Technology Oil-free, magnetic bearing compressor technology eliminates complex oil and refrigerant lubrication management systems resulting in a simplified chiller design, increased reliability and reduced maintenance.
Oil-free, magnetic bearings and integrated variable speed drive delivers industry leading efficiency with no performance degradation over the life of the compressor.
Permanent magnet synchronous motor provides high efficiency and enables compact design.
Two stage compression design provides flexibility to use for water-cooled and air- cooled chiller applications.

Without oil in the system, there is no performance degradation due to oil contamination or mechanical wear. This, along with the contact-free operation enabled by magnetic bearings means the performance remains consistent over the life of the compressor. Zero Performance Degradation
