Circulating air freezer

Mini Ultra- Low Temperature Refrigerator Exclusive Use – Circulating air freezer
Description & Application:
1.Widely used in small medical refrigerator,confidential equipment
assembly line of low temperature freezer.
2.Independent refrigerated air recirculating unit and can operate
directly without professional knowledge of refrigeration,it is
relatively independent of cold storage and cryogenic box.
3.Can work for a long time continuosly,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 cold storage&cryogenic box in the process of
defrost in evaporation system.
6. Easy installation ( joint the box according to mechanical
drawing,connect the electricity and water and set temperature
completely to work)
