Detail
Parameters
Features of cascade unit:
 
◆Environmental protection natural working medium is used for high and low temperature
◆Plate and shell heat exchanger is used for NH3 low charge and CO2 condensation to improve system safety and ensure personal and food safety.
◆Modular design, high integration, so as to reduce the area of the machine room and shorten the construction period
◆CO2 screw compressor adopts semi closed structure to reduce the leakage of refrigerant and oil; frequency conversion motor adopts siphon cooling to save energy and reduce consumption
 
Application: NH3 / CO2 Cascade unit can be widely used in low temperature cold storage and quick freezing of food processing industry, low temperature process cooling of medicine and chemical industry, etc.
 
Scope of application: evaporation temperature: - 52 ℃ ~ - 20 ℃, condensation temperature ≤ 40 ℃.
