Principle
The refrigeration system adopts cascade refrigeration, which is composed of high temperature part and low temperature part, and is connected by evaporative condenser. The heating system is composed of high power resistance wire to achieve rapid heating up. The temperature and humidity system is divided into two subsystems of humidification and dehumidification. The humidification adopts steam humidification method, and the dehumidification adopts mechanical refrigeration dehumidification and drying dehumidification. The Sensor system adopts platinum resistance and Thermocouple temperature sensor, as well as solid state electronic humidity Sensor for measurement.
Applications
Plastics, electronics, food, clothing, vehicles, metals, chemicals, building materials

Notice
• Power supply voltage 220V AC (+/- 10%)
• Protective ground wire must be used, ground resistance ≤ 4Ω
• Do not use knife switch or power socket, use air switch (40A)
• The resistivity of humidification water needs to be ≥ 500MΩ
• The weight of the product rack does not exceed 20 kg
• Pay attention to the upper and lower limit temperature protection function
• When operating, the start-stop function needs to be locked to prevent accidental touch
• Periodic temperature sensor calibration
• Note that equipment safety devices include air burn prevention, high voltage protection, overheating protection, etc
