Walk-in Constant Temperature And Humidity Test Chamber

1, Compressor protection measures

1) Compressor exhaust temperature adjustment: automatically adjust the compressor exhaust temperature, so that the compressor temperature is kept within the normal range, so that it operates in the best condition, avoid the compressor overcooling and overheating, and extend the service life of the compressor (compressor undercooling: the refrigerant oil thickens, may cause the compressor oil shortage, compressor damage; compressor overheating: resulting in a reduction in the insulation performance of the compressor coil, further burning the compressor)

2) In order to ensure the long-term reliable operation of the compressor, the exhaust and return end of the compressor is equipped with a temperature transmitter, which is controlled by PLC, so that the compressor can operate under normal conditions.

2, High temperature compressor opening measures

Automatically adjust the compressor exhaust temperature, so that the compressor temperature is kept within the normal range, even if the compressor is opened at 100 ° C ~ 150 ° C for cooling, the refrigeration system will not overheat protection

3, Energy saving measures (cooling capacity PID adjustment)

Equipped with cooling capacity adjustment device, such as evaporation temperature adjustment, energy regulation, hot gas by-pass energy regulation to ensure that under the premise of meeting the main technical indicators, reduce the equipment energy consumption, at any low temperature point constant temperature, no heating balance. Different from the traditional, simple refrigeration bypass (need heating balance, waste energy), so that the use of power reduced by 40%, can save the use of operating costs, which is the most advanced control method in China

4, Advantages of temperature program control instrument

Germany Siemens programmable controller, independent intellectual property rights of the special control software, more than the general controller to achieve high-precision control of environmental test equipment, control inertia, drift ideal

5, Strong carrying capacity

Test specimen in the environmental test process is very common requirements, due to the difference in control mode and control principle, the load capacity of the environmental test equipment of various enterprises is very different, my company's products not only in the low temperature segment and strong load capacity, in the high temperature segment also has a strong load capacity

6, Solenoid valve long service life

The frequent start and stop of the solenoid valve and in the environmental test conditions of high and low temperature cold and thermal shock, the sealing performance of the solenoid valve will be severely tested, my company after 5 to 8 months of intermediate test, has changed the Italian CASTEL solenoid valve to the United States "Emerson" solenoid valve, greatly improving the overall reliability of the product

Touch type programmable temperature and humidity controller

It is temperature and humidity programmable controller which equips with the general control, heating and cooling function by supporting high definition TFT-LCD touch screen and SD card.
