Overview
HZAOC GDJS-50A High and Low Temperature Alternating Damping heat testing chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, as well as the adaptability test of storage, transportation and use in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, and the outer side is sprayed Cold rolled steel plate, with good thermal insulation performance.
2. The door is made of double-decked silicone rubber sealing material, and the sealing is reliable.
3. The observation window is a multi-layer conductive film tempered hollow Glass, built-in anti-frost heating wire and lighting.
4. The side of the box is equipped with a test hole with a silicone rubber plug, which has both thermal insulation efficiency.
5. Adopt French "Taikang" fully enclosed Compressor, use R404A environmentally friendly refrigerant, and the refrigeration system is safe and reliable.
6. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
7. Adopt steam boiler electric heating and humidification method, with water level control and anti-dry burning device.
8. High Accuracy Digital Temperature and Humidity Controller for accurate and stable control.
9. The control system is equipped with comprehensive safety protection measures, including over-temperature protection and phase loss protection.
10. Equipped with an independent over-temperature protector to provide double security.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through evaporators, electric heaters, humidifiers and fans in the air conditioning cabinet. Temperature control is realized through the refrigeration system (Compressor, evaporative condenser) and the heating system (electric heater controlled by PID); humidity control is realized through the humidification system (electric heating tube steam boiler controlled by PID). The control system precisely adjusts the output of refrigeration, heating and humidification according to the feedback of the Sensor to simulate the required temperature and humidity environment. The box adopts the upper air supply and lower air return mode to ensure uniform temperature and humidity.

Notice
* Power supply voltage meets requirements (380V +/- 10%) before use.
* When the equipment is running, do not open the door frequently, so as not to affect the test accuracy and equipment performance.
Please pay attention to the total power range of the equipment (3~ 13.5KW) to ensure that the power supply line capacity is sufficient.
* Regularly check the sealing parts such as test hole plugs to ensure that they are in good condition to ensure the stability of the environment in the box.
The equipment is equipped with a variety of safety protection devices. If the fault indicator light is on, please check the cause or contact a professional first.
The humidification system is equipped with a water level control and anti-dry burning device. It is still necessary to check the water level regularly to avoid dry burning.
The refrigeration system uses environmentally friendly refrigerants, and maintenance should be carried out by professionals.
After the equipment is out of use, it is recommended to perform proper cleaning and maintenance.
