Freezing system:

1. Compressor: France imported original compact compressor

2. Refrigerant: environmentally friendly refrigerant

3. Condenser: air-cooled condenser

4. Evaporator: fin-type multi-stage automatic load capacity adjustment

5. Other accessories: desiccant, oil separator, high and low pressure repair valve, protection switch

6. Expansion system: capacity control of the refrigeration system

Temperature and humidity regulation: balance of temperature control and humidity control, to P.I.D. way to control the SSR, the system heating and humidification is equal to the amount of heat loss, it can be long-term use of stability.
