2.Customized sizes and configurations available

4. Control method and characteristics:
Precision microcomputer control temperature and humidity system, with PID, control the refrigerant flow to make the system's heating/humidification reduction, to achieve low power consumption, energy-saving, carbon reduction effect, cooling, heating, humidity control intelligent electronic control, long-term stable use.
 
Flexibility for structure
The panels used in our chamber are 4" (100mm or 150mm) Thick urethane-foam sandwiched between a stainless-steel interior wall and a coated-steel exterior. An assembled box is self-supporting. So that no heavy structural members are required. Different door sizes, flooring upgrades, access ports, and other modifications are possible.
 
Widest test range, most customizable
