Latest model servo system
Technological advantage
Energy saving of over 30%(Machine running can last one year);
1/3 lifespan more than traditional technology;
Save water (low water consumption during humidity test, full drainage of water to ensure clean waterways and low failure);
4.The evaporator is not easy to frost (long-term high humidity, low temperature);
5.Linear models are more convenient to implement
6.Temperature and humidity are stable and fast, and the uniformity is better controlled;
7.Compressor is not easy to frost, lifespan longer;
8.Non-standard design is more convenient;
9.ESS box load heating automatic adaptation
10.Low humidity high humidity and apple phone test curves easily done.
