Water Cooled Chillers and Heat Pumps


Cool. Cap.: 26-193 kW - C.O. , H.P. & Condenserless - Scroll

Compact and durable design:
A fully enclosed single refrigerant circuit unit designed for internal plant room locations has minimum size for maximum cooling capacity. The unit construction is galvanised steel coated with baked-on powder paint RAL 9001 for durability. Design is based on 2 casing frames, providing a high level of standardization.

Integrated Pump Kits:
A complete range of pump kit combinations can be ordered factory fitted.
