Oil-free centrifugal compressor platforms

Built around the duty point.

Magnetic-bearing centrifugal refrigerant compressors for OEM-developed data-center chillers and thermal systems.

The compressor platform is one part of the system. Chiller architecture, refrigerant circuit and site performance remain project-engineered.

Published standards

Where these terms are defined

Catalog fields on this page are supplied values. The standards below define how they are rated and coded. They are references, not a third-party rating of this equipment.

Capacity and efficiency

ANSI/AHRI 550/590 (I-P)

The rating method behind chiller capacity and efficiency figures, including the integrated and non-standard part-load values (IPLV, NPLV).

Open at AHRI

Enclosure protection

IEC 60529

The IP code behind enclosure ratings, with the tests that verify each digit and a scope limited to electrical equipment up to 72.5 kV.
