Overview
KESIONOTS KS-HD1000LB low/high temperature test chamber is an environmental test equipment for high temperature and low temperature Reliability test of industrial products. It is suitable for high temperature, low temperature (alternating) cyclic change conditions of parts and materials of electronic and electrical, automotive and motorcycle, aerospace, marine weapons, colleges and universities, R & D institutions and other related products for performance testing, for product design, improvement, identification and inspection, such as aging test.
Features
1. Temperature range: -70 ℃, -60 ℃, -40 ℃, -20 ℃ to 150 ℃.
2. High Accuracy Temperature Control system, analysis accuracy of +/- 0.1 ℃, control accuracy of +/- 1 ℃.
3. The box structure is sturdy, the outer box is made of high-grade cold-rolled sheet paint, and the inner box is made of stainless steel.
4. Equipped with an efficient chilling down system, Air-Cooled/single-stage Compressor or wind, Water-Cooled/double-stage Compressor can be selected according to temperature requirements.
5. Built-in multiple Safety protection devices, including no fuse switch, Compressor overload protection, refrigerant high voltage protection, over temperature protection, etc.
6. Optional well-known brand controllers (such as Korean "TEMI" or Japanese "OYO") and Compressors (such as "Taikang" or German Bitzer).
7. The studio has a capacity of 1000L and an inner box size of 100 * 100 * 100cm, meeting the needs of larger sample testing.
Principle
The low/high temperature test chamber simulates and precisely controls the required extreme temperature environment in a closed box through a refrigeration system and a heating system. The refrigeration system (e.g. Compressor) is used to reduce the temperature in the box, and the heating system is used to raise the temperature. Coordinated control of the two is carried out by the High Accuracy controller to achieve the set Temperature range, rate of change and uniformity, so that the test sample placed in the box can be Reliability test.
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
1. Place the device in a suitable location and connect it to the required power supply (220VAC +/- 10% 50/60Hz or 380VAC +/- 10% 50/60Hz).
2. Open the box door and place the sample to be tested on the shelf in the box to ensure that it does not affect the internal air circulation.
3. Close the box door and set the required test temperature, Linear dispersion, time and other parameters through the controller (such as TEMI or OYO).
4. Start the equipment, the refrigeration and heating system starts to work, and the environment in the box changes according to the set program.
5. During the test, the sample status can be observed through the viewing window, and external connections can be made using test holes if necessary.
6. After the test, the equipment stops running according to the program. After the temperature in the box returns to a safe range, open the box door to remove the sample.
7. Power off the equipment and perform necessary cleaning and maintenance.
Notice
• Equipment should be installed in a well-ventilated, non-direct sunlight, away from heat sources and flat ground.
• Power supply voltage is stable and meets equipment requirements (220VAC +/- 10% or 380VAC +/- 10%).
When placing samples, the total volume should not exceed two-thirds of the volume of the studio, and the air duct should not be blocked.
• During operation, do not open the door frequently, so as not to affect the Temperature Stability and equipment life.
Equipment is equipped with a variety of protective devices. When the alarm system is triggered, the cause should be identified and troubleshooted before use.
• Regularly check the operation status of the chill down system (e.g. Compressor) to ensure good heat dissipation (Air-Cooled) or normal water supply for chill down (Water-Cooled).
• After the low temperature test, if the box is frosted, it should be naturally defrosted and dried at room temperature to avoid directly scratching the surface of the inner box.
• Non-professionals should not disassemble or modify the electrical components of the equipment, and be sure to cut off the main power supply before maintenance.
