Energy-saving Large Custom Size Environmental Walk in Climate Test Chamber Adopting PID principle of technology to achieve low-temperature energy-saving operation  low temperature working state, the heater does not participate in the work, through PID regulates the flow rate and flow direction of the refrigerant, and regulates the three-way flow of the refrigerant pipe, the cold bypass pipe, and the hot bypass pipe to achieve automatic constant temperature to the working chamber. This method can reduce energy consumption by 30% under low temperature conditions. The technology is based on Danish Danfoss' ETS series of electronic expansion valves, which can be used to smoothly adjust the cooling capacity for different cooling capacity requirements, that is, to achieve the compressor cooling capacity adjustment when different cooling rate requirements are met.

APPLICATIONS

This product is suitable for complete machine or large parts with low temperature,high temperature,high-low temperature change,constant temperature,high-low temperature cycles test etc.Chamber dimension and function could be provide according to customerspecifications;elegant appearance with flight block style chamber;scientific air flue design and can match the different clients'requirement.Adopt to touch screen,programmable logic controller (PLD).

FEATURES

1.Walk-in chamber has a big temperature / humidity range and can meet user’s entire requirement. It adapts to unique balance thermoregulation & humidifying way and can get a safety, precise temperature humidity environment. It has stability, balance heating, humidifying function and also can proceed in high precision, high stability temperature humidity control.

2.Walk-in test room is equipped with high precision intelligentized thermoregulator, temperature and humidity adapt LCD display control 7551 program instrument ( it also can use OYO-5461 according to user requirement), can choose the temperature humidity recode instrument.

3.Walk-in test room can choose computer for remote control according to the function.

4.Automatic select the refrigerating circuit, the automatic control instrument can automatic choose operate refrigerating circuit’s function according to the temperature set value, and direct-on line starting refrigerating machine in high temperature condition which can cooling directly.

5.The interior door is equipped with big observation window which convenient for viewing the test status of specimen.

6.Walk-in room is equipped with advanced safety protection device --- residual current device; overheat protector, phase failure protector, water-break protector.
