Air-cooled chillers
Review the condensing-temperature range, ambient profile, lift and expected part-load operation.
Data-center cooling
Compressors for mission-critical chillers.
YACI supplies oil-free magnetic-bearing centrifugal compressor platforms for OEM-designed air- and water-cooled chillers.
The chiller, chilled-water system, heat rejection equipment and site controls remain within the OEM and project engineering scope.

Application paths
Start from the chiller architecture.
Compressor selection follows the refrigerant circuit and required operating envelope—not a nominal capacity value alone.
Water-cooled chillers
Define cooling-water conditions, control sequence and plant-level operating points before selection.
Controls integration
Align compressor, drive, chiller controller and site supervisory requirements during platform development.
Engineering inputs
What an application review needs.
Provide the design and boundary conditions that shape compressor selection and controls discussion.
- Target refrigerant and requested market
- Cooling capacity at named rating conditions
- Evaporating and condensing ranges
- Electrical supply and control architecture
- Part-load, restart and redundancy requirements
- Acoustic, dimensional and service constraints
OEM application review
Bring the operating envelope, not just the tonnage.
YACI can review the documented product families against your stated application inputs. Final selection data is supplied per project.
