Air-cooled screw chiller (heater)
Canatal SGA series air-cooled screw chiller (heater) unit is an air conditioning host device that provides chilled (hot) water sources for terminal equipment in central air conditioning systems. The unit can be installed outdoors on the roof or ground. No special machine room, cooling tower, cooling water pump, or cooling water pipe system is required.
The unit uses the environmentally friendly refrigerant R134a and is a completely independent, integrated unit. Each unit includes a screw compressor, air heat exchanger, dry water heat exchanger (optional film evaporator), hydraulic module (optional), electronic expansion valve, and microcomputer control center. The cooling capacity ranges from 300 kW to 1350 kW, with optional ethylene glycol and ethylene glycol-free natural cold source solutions.
Application Scenarios
Widely applicable to various data centers or places requiring refrigeration/heating, such as electronics, chemical, metallurgical, pharmaceutical, and museum industries.
Features and Value
