1. It is widely used in high and low temperature testing of semiconductor equipment. Cold and heat sources for high temperature and low temperature constant temperature test of electronic equipment;
2. Independent refrigeration cycle fan unit;
3. It can work continuously for a long time and defrost automatically. The defrosting process does not affect the storage temperature;
4. Modular design, easy replacement of standby unit (if there are 10 units, only one standby unit can be used);
5. Solve the problem of frequent door opening and closing and frosting of evaporation system; The defrosting process of the evaporation system has no influence.
6. It is simple to build a set of high and low temperature constant temperature chamber transformer (according to the drawings provided, the box shall be spliced like building blocks, the electricity and water shall be connected, and the work can be started after the temperature is set)
