Overview
KESIONOTS KS-HD1000LA low/high temperature test chamber, also known as Environmental Test Chamber, is suitable for high temperature and low temperature Reliability test of industrial products. The equipment is used for electronic and electrical, automobile and motorcycle, aerospace, ship weapons, colleges and universities, R & D institutions and other related products. Components and materials are tested under high temperature and low temperature (alternating) cyclic change conditions to inspect their performance indicators and serve product design, improvement, appraisal and inspection.
Features
Temperature range up to -70 ° C to 150 ° C.
2. Provide 1000L large-capacity studio with an inner box size of 100 * 100 * 100cm.
3. Temperature control accuracy, analytical accuracy of +/- 0.1 ℃, control accuracy of +/- 1 ℃.
4. Using high-quality materials, the outer box is high-grade cold-rolled sheet paint, and the inner box is stainless steel.
5. Equipped with a variety of protection devices, such as no fuse switch, Compressor overload protection, over-temperature protection, etc., to ensure safe operation.
6. Optional well-known brand controllers (such as Korean "TEMI" or Japanese "OYO") and Compressors (such as "Taikang" or German Bitzer).
7. The chilling down system is configured according to the temperature requirements, -20 ℃ adopts Air-Cooled single-stage Compressor, -40 ℃~ -70 ℃ adopts wind and Water-Cooled double-stage Compressor.
Principle
The low/high temperature test chamber simulates and precisely controls the required extreme temperature environment in a closed box through the refrigeration system (Compressor) and heating system. The controller receives the feedback signal from the temperature sensor and instructs the refrigeration or heating system to work, so that the temperature in the box changes or remains constant between high temperature and low temperature according to the set program to test the performance and Reliability of the sample under temperature stress.
Applications
Electronics and electricians, automobiles and motorcycles, aerospace, ships and weapons, colleges and universities, R & D institutions
Standards
GB2423.1、GB2423.2、GJB150.3、GJB150.4、IEC、MIL
Steps
Place the equipment in a smooth, well-ventilated area and connect it to the required power supply (220VAC +/- 10% 50/60Hz or 380VAC +/- 10% 50/60Hz).
2. Open the box door, place the sample to be tested on the Shelf in the box to ensure that the air circulation is not affected, and then close the box door.
3. Set the required test temperature Linear dispersion, time, rising and cooling rate and other parameters through the controller (such as TEMI or OYO brand).
4. Start the equipment, the refrigeration and heating system starts to work, and the temperature in the box changes according to the set program.
5. During the test, the sample status can be observed through the viewing window, and if necessary, an external test circuit can be connected through the test hole.
6. After the test, the equipment stops running or returns to normal temperature according to the program. After the temperature in the box is safe, open the box door to remove the sample.
7. Turn off the total power supply of the equipment and perform necessary cleaning and maintenance.
Notice
* The equipment should be installed in a well-ventilated, non-direct sunlight, away from heat sources and flat ground.
* Power supply voltage is consistent with equipment requirements (220V or 380V) and is reliably grounded.
When placing samples, the total volume should not exceed one-third of the volume of the studio to ensure the normal circulation of air in the box.
* It is forbidden to test flammable, explosive, volatile and highly corrosive items.
* During the operation of the equipment, do not open the box door frequently, so as not to affect the temperature stability and increase the Compressor load.
* If you need to run at low temperature for a long time, check regularly and may need to defrost the Compressor.
Pay attention to the status of various protective devices (such as over-temperature protection) of the equipment, and check the fault in time when alarming.
Perform regular equipment maintenance, clean condenser, check refrigerant pressure and electrical connections.
Non-professional personnel should not disassemble or repair equipment, especially refrigeration systems and electrical components.
