About Maintenance

Centrifugal Chillers

The operation of centrifugal chillers is based on the high-speed rotation of the turbine and gears. Therefore, lubricant replacement is important for maintaining optimal performance.

About Overhaul Maintenance

CENTRIFUGAL CHILLERS

Hermetic parts that cannot be disassembled for inspection during regular maintenance (compressor, etc.), require periodic overhaul.
