(Screw)

Industrial air-cooled chiller with semi-hermetic screw compressor for low temperature cooling ranging from -30° to 0°C

Refrigerant: R22/R404A
Power source: 3Ph 380V~415V 50Hz/60Hz
Compressor: semi-hermetic screw compressor
Chilled water temperature range: -30°C to 0°C (adjustable temperature)
Min. dimensions (L×W×H): 2530×1700×1960mm

These large-capacity air-cooled low-temperature chillers are engineered for demanding applications in non-ferrous metallurgy, electronics, chemical processing, food production, air separation, and hydrogen energy cooling. Operating temperatures can be precisely set between -30°C and 0°C, making them suitable for diverse industrial processes.

These industrial air-cooled chillers are equipped with Bitzer or Hanbell semi-hermetic screw compressors, along with components and electrical controls from leading global brands, to ensure reliable and consistent performance. The PLC control system with HMI touch interface offers intuitive operation, while units can be customized to match specific site conditions and process requirements.
