Refrigerant: NH3/CO2 Nominal Working Condition: -38/+40℃ Unit Cooling Capacity: 271—526KW CO2 Pump Flow: 6-10m³/h NH3 Filling Amount: 110-220Kg CO2 Filling Amount: 2700—5200Kg

The unit adopts NH3 and CO2 refrigerants which are safe, environmental friendly and energy saving, with excellent environmental protection performance.

Modular design, equipped with container housing, no need for machine room, easy for operation and maintenance;

Frequency conversion start and run, no impulse current, significant energy saving advantage;

High degree of system automation reduces the manual commissioning time and the operation cost;

Integrated active defense system, real-time monitoring and alarm, with spray device, high safety;

The cooling capacity per unit volume of CO2 is higher, and the heat transfer efficiency is higher;

As refrigerant, CO2 has excellent transmission and heat transfer performance.

AIST series carbon dioxide modular units are widely used in cryogenic refrigeration in food processing, low-temperature process cooling in pharmaceutical and chemical industry, process cooling in dangerous operation area, artificial environment and other fields.
