LISUN has been building the most recognizable environmental testing equipment in the industry. Every chamber sold is highly recommended in the market. LISUN has helped companies, small and large, create more reliable products as the most fully-featured environmental chamber on the market.
LISUN’s environmental chambers are the high-performance solution to your testing needs. With our advanced air baffle design, the chambers help efficiently identify the product design flaws and process weaknesses, improving product quality and reliability.
environmental chamber GDJS-015B
LISUN’s environmental test chambers (GDJS-015B) are available as temperature only or temperature humidity units. Humidity testing can be added as a field retrofit. With a wide range of size and performance configurations available, every chamber can be customized to fit your specific testing needs. The dimensions of these environmental chambers vary depending on the type of the product to be tested.
A single environmental chamber can perform several different tests when outfitted with the popular models. The benefits of environmental test chambers include improving product strength and reliability, reducing risks of warranty as well as meeting a wide range of industry-standard test specifications.
The thermal shock chamber can be divided into two zones and three zones. The difference between 2 zones and 3 zones is the inner chamber structure and test method. The 3 zones consist of a hot zone, a cold zone, and a test area. The test sample is placed in the test area. The 2 zones consist of a hot zone and a cold zone. The test sample is placed into the basket.
Thermal shock testing subjects to the alternating extremes of high and low temperatures. This is done in order to observe the product changes in characteristics failure caused by different materials and thermal expansion. The high temperature can reach 200 degrees Celsius, and the low temperature can reach -70 degrees Celsius. You can control the temperature switch time within 5 seconds, and temperature recovery time can be controlled within 5 minutes.
The cooling method can be customized according to the installation site and equipment size.
The inner chamber material uses 1.2 mm thickness, SUS304 stainless steel fully welled with excellent sealing performance and temperature uniformity. The external material is made of a cold-rolled plate. It has gone through brushing, polishing, and painting treatment.
The insulation material is made of polyurethane foam, and the insulation thickness is 130 mm. Chamber is also equipped with reinforced sheet material. The door seal adopts double silicon rubber sealing material with excellent sealing performance. The observation window has 4 layers of tempered glass, the size you can choose.
In addition, in order to prevent the glass from frosting when running at a low temperature, we set up a heating wire with a safety voltage of 24V. We set up an LED lamp on the window to provide lighting for observation. Both sides of the chamber are equipped with a test cable port with a diameter of 100 mm.
The plug material is silicone rubber, has high low-temperature resistance, and also could preserve heat. Through the valve control, the air is circulated inside the chamber.
The refrigeration system is a two-stage system. It means that we can use two compressors in the system. By using a 2 sets of compressors, we can guarantee not only the cooling rate but also energy saving and extend the life of the compressor. The significant parts of the cooling system are compressors, evaporators, condensers, oil separators, and filters.
In this chamber, we usually use two semi-closed compressors. The refrigerant is R404 and R23. The cooling method of this chamber is water cooling, and this is a water cooling condenser that is customized and connected to the water pipe. A solenoid valve is used to control the flow of the refrigerator to save energy.
The circuit system wiring is according to the international standard, and the layout and color of wires are compiled with international standards. It is equipped with a number line to facilitate maintenance.
The controller of this chamber uses a self-designed and developed controller. It controls the temperature. The controller has a color touch screen of 7 inches. It is very convenient when we use it. In operation mode, you can choose fixing or programming. You can program 120 groups, each group has 99 segments and 999 cycles in total, and this controller has the multi-language.
Every set of our equipment is equipped with an internal power supply system, which is conveniently supplying power for the testing samples. Our chambers are equipped with pressure meters. So, customers can quickly check the pressure.
Environmental testing helps in the simulation of various environmental conditions that a product can undergo during its lifetime. In addition, it also helps in the simulation of lifecycle environments that a product encounters.
In thermal shock testing, the device under test is placed inside the basket. This basket automatically moves between the hot and cold zones. You can easily manage the temperature of these zones by the air-to-air or liquid-to-liquid system.
