Efficient Industrial Cooling with BITZER Screw Compressors
MASTERTECH air-cooled industrial water chillers are supplied factory-assembled, with refrigeration circuits, internal piping and electrical wiring completed and ready for site installation.
Each unit undergoes factory pressure testing, refrigerant charging and operational testing with water circulating through the evaporator to verify correct refrigeration circuit operation.
Equipped with BITZER semi-hermetic screw compressors and automatic capacity control, MASTERTECH chillers are designed to deliver reliable, efficient cooling for centralised industrial chilled water systems and demanding manufacturing applications.
Cooling Capacity: 350–2,600 kW
