Overview
HZAOC GDJS-800D 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, and can also be used for storage, transportation and adaptability testing of products in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is SUS304B stainless steel, the outer side is sprayed Cold rolled steel plate, and the thermal insulation layer is made of ultra-fine Glass thermal insulation cotton.
2. The door is made of double-decked silicone rubber sealing material to ensure sealing.
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 equipped with high voltage control, overvoltage, overload and other multiple protections.
6. The heater adopts porcelain frame nickel-chrome wire electric heater, which has little thermal inertness and long service life.
7. The humidification system adopts steam boiler electric heating and humidification method, and is equipped with water level control and anti-dry burning device.
8. The control system adopts High Accuracy Digital Temperature and Humidity Controller, equipped with PT100 Sensor, stable and reliable control.
9. The control system is equipped with multiple safety protections such as phase loss, phase sequence error, over-temperature power failure, leakage, and independent over-temperature protectors.
10. The air supply method is the upper air supply and the lower air return, and the temperature sensor is placed in a trend.
Principle
The test chamber adjusts the temperature and humidity of the air in the working room through the evaporator, electric heater, humidifier, fan and other equipment in the air conditioning cabinet. The refrigeration system adopts a cascade refrigeration cycle, and the low-temperature grade refrigerant evaporates in the evaporation condenser to absorb heat to achieve cooling; the heating system controls the electric heater to work through a solid-state relay; the humidification system heats water through an electric heating pipe to generate steam. The control system adjusts the output of refrigeration, heating and humidification according to the temperature and humidity signal fed back by the Sensor, so as to realize the set high and low temperature alternating heating and humidity environment.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environment storage adaptability test, transportation adaptability test, use adaptability test

The data did not mention specific compliance criteria
Steps
The information does not provide specific operation steps
Notice
• Power supply voltage 380V +/- 10%.
• When the circulating fan is not started or overloaded, the heating and humidification system will not start.
• Please ensure that the safety protection device (such as phase loss protection, over-temperature protector, etc.) functions normally before use.
• Pay attention to the water level of the humidification system to prevent the heater from dry burning.
• When running at low temperature, pay attention to the possibility of frost in the observation window, and the built-in heating wire can enable anti-frost.
• Regularly check the refrigeration system pressure and protection devices to ensure safe operation.
The total power of the equipment is between 3 and 13.5KW. Please pay attention to the line load capacity.
