| Adiabatic property | Climate chamber walls and doors should have effective thermal insulation |
| noise | The noise value during the operation of the climate chamber shall not exceed 60dB |
| Continuous working hours | The continuous working time of the climate chamber shall not be less than 40 days |
| *Humidity control methods | The intelligent combination of dry wet method and dew point method is used to control the relative humidity of the working cabin. Taking advantage of the advantages of dry wet method and dew point method, the set humidity can be quickly reached within one hour through dry wet method. After reaching the set humidity, it automatically switches to dew point method to assist in humidity control, achieving very stable results. The humidity fluctuation is basically not more than 1.5%, far superior to the standard requirement of 3%. And it will not generate water droplets on the bulkhead; |
| control system | The touch control screen is used as the dialogue interface for personnel to operate equipment. The Siemens PLC control system in Germany uses the touch control screen as the dialogue interface for personnel to operate equipment. It can directly set and display the temperature, relative humidity, temperature compensation, dew point compensation, dew point deviation, temperature deviation, working time inside the box, and can automatically record and draw control curves. |
| Refrigeration system | We use ASPERA compressor imported from Italy. |
| Security protection system | Refrigeration system high pressure and overcurrent protection, heater overtemperature protection, motor overcurrent protection, water shortage protection, air pump overheating, overcurrent, overpressure protection, etc. |
