1. Widely used in the semiconductor device for testing high and low temperature.
2. Independent refrigerated air recirculating unit.
3. Can work for a long time continuously, defrosting automatically and it can not affect the storage temperature in the process of defrosting.
4. Modular design and replace easily for standby machine,(If there are 10 sets of machines, only one standby machine is enough).
5. Solve the problems of open or close the door frequently and frosting problem in evaporation system, it will not affect the temperature of the cold storage&cryogenic box in the process of defrosting in evaporation system.
6. Easy installation (joint the box according to mechanical drawing, connect the electricity and water and set temperature completely to work).
