Product Applications
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.
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.
Evaporative Condenser/Cooler (Wet Air Cooler)
The evaporative condenser/cooler (wet air cooler) uses moisture evaporation and strong air circulation to take away the heat of condensation to cool industrial gas or high-temperature and high-pressure superheated steam discharged from the compressor to condense it into liquid. Related products include counter-flow evaporative condensers, parallel flow evaporative condensers, composite flow evaporative condensers, composite air coolers, evaporative condensers, composite condensers, falling film evaporative condensers, closed cooling towers, etc.
Red Water Unit
The device is a perfect combination of pre-cooling technology and refrigeration for poultry slaughtering. lt uses a high-effciency falling film evaporator with pump for liquid supply and high-performance automatic control device, which has high heat exchange efficiency, anti-icing and fouling, and significantly reduces system energy consumption.
Automatic control valves, manual valves, differential pressure level gauges, pumps are from well-known brands.
The heat exchange tube (waterway) is made of food grade 304 stainless steel.
Applicable Fields:
Applicable to immersion cooling processes such as livestock and poultry processing cooling, aquatic product processing cooling, fruit and vegetable pre-cooling, etc.
