Overview
HZAOC GDJS-150D High and Low Temperature Alternating Damping heat testing chamber is suitable for inspecting the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, and can also be used to evaluate the storage, transportation and adaptability of products in high and low temperature environments.
Features
1. The box adopts the overall structure, the inner side is stainless steel plate, the outer side is sprayed steel plate, and the thermal insulation performance is good.
2. The door is sealed with double-decked silicone rubber 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. Equipped with test holes with silicone rubber plugs for both thermal insulation performance.
5. Adopt French "Taikang" fully enclosed Compressor, use 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 a variety of safety measures and is equipped with an independent over-temperature protector.
10. The air supply method is the upper air supply and the lower air return, and the temperature is uniform.
Principle
The test chamber realizes a low temperature environment through a refrigeration system (using a cascade refrigeration cycle, and a high-temperature evaporator doubles as a low-temperature stage condenser), realizes a high temperature environment through an electric heating system, and generates steam through electric heating to realize humidification. The control system coordinates the work of the refrigeration, heating, humidification and circulating fan according to the set temperature and humidity program, and forms a uniform and controllable temperature and humidity environment in the chamber to simulate the climate conditions that the product may encounter in practical applications.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environmental adaptability test, storage test, transportation test, use adaptability test
Standards
The data did not mention specific compliance criteria
Steps
Connect the device to a 380V +/- 10% power supply.
2. Set the required Temperature range (-60~ 150 ℃), Humidity range (30~ 98% RH) and timing time (0~ 999 hours) through the buttons on the operation panel.
3. Start the equipment and the circulating fan starts to work.
4. The control system automatically controls the operation of the refrigeration, heating and humidification system according to the set value to achieve and maintain the set temperature and humidity environment.
5. During the test, the sample status can be observed through the observation window.
6. Automatically stop or manually end the test after the test reaches the set time.
Notice
* The power requirements of the equipment are 380V +/- 10%, and it is necessary to ensure that the power supply meets the requirements.
The total power of the equipment is between 3 and 13.5KW, and a line with corresponding capacity is required.
* Check the phase sequence before starting, and the device has protection functions such as phase sequence errors.
When the circulating fan is not started or overloaded, the heating and humidification system will fail to start.
The humidification system is equipped with water level control and anti-dry burning devices to ensure that the water source is normal.
The refrigeration system uses R404A environmentally friendly refrigerant and is monitored by a professional protection system.
The equipment is equipped with an independent over-temperature protector, but it is still necessary to regularly check the operating status of the main controller.
* When using the test hole, attention should be paid to the sealing and insulation of the stopper.
* Avoid opening the door for a long time during low temperature operation to prevent frosting or affect Temperature Uniformity.
Perform regular equipment maintenance to ensure the normal operation of fans, heaters, humidifiers, and other components.
