Product features
01
Energy saving of over 30%(Machine running can last one year);
02
1/3 lifespan more than traditional technology;
03
Save water (low water consumption during humidity test, full drainage of water to ensure clean waterways and low failure);
04
The evaporator is not easy to frost (long-term high humidity, low temperature);
05
Linear models are more convenient to implement
06
Temperature and humidity are stable and fast, and the uniformity is better controlled;
07
Compressor is not easy to frost, lifespan longer;
08
Non-standard design is more convenient;
09
ESS box load heating automatic adaptation
10
Low humidity high humidity and apple phone test curves easily done.
