Why Use R744 Refrigerant?
1. Low operating cost:cheap and easy to buy
2. High safety: CO2 is non-toxic, non-flammable, non-flammable, non-corrosive to equipment, and has stable chemical properties
3. Technical advantages: widely used in Europe, R744 is more environmentally friendly than other refrigerants and will not destroy the ozone layer
4. Lower temperature: Cascade units can easily reach room temperature of -30°C.
Why Use CO2 Secondary System？
There is no refrigeration oil in the evaporator and pipeline of the cold room, which greatly improves the heat transfer efficiency of the evaporator and improves the COP of the refrigeration system.
The Heat Exchange Temperature Difference Is Smaller
The heat exchange temperature difference between the refrigerant and the cold room temperature is smaller, and the frost formation rate on the evaporator surface is greatly reduced during the cooling period.
Configurable Container Shell
No need to build the machine room ,and all the test will be done before delivery ,it can running after connect the wire and pipe on spot after received the goods.
