high-low temperature chamberHeating, cooling, and dehumidification system

1. The high and low temperature chambers are heated using far-infrared nickel chromium alloy high-speed heating electric wires;
2. High temperature independent system, does not affect low-temperature testing;
3. The humidity is achieved by using stainless steel tubes with nickel chromium alloy high-speed heating wires and high-temperature magnesium oxide powder, which have fast reaction time and long service life.
4. The refrigeration compressor adopts fully enclosed French Taikang, with mechanical refrigeration for cooling or dehumidification and forced air cooling for condensation;
5. The heating and cooling system is independent, and the drying filter, refrigerant flow window, repair valve, oil separator, solenoid valve, and storage tank are all original parts.
6. Ultra low temperature or large volume low-temperature test chambers use German "valley wheel" air-cooled and water-cooled compressors.

2、 Structural Designhigh-low temperature chamber

The surface is treated with spray coating, with a curved design and smooth and natural lines.
2. The inner liner is made of SUS304 stainless steel plate, which can continuously control the test temperature difference within ± 2 ℃.
3. The indoor sample rack and other accessories are made of SUS304 stainless steel material.
4. The insulation material for the equipment is high-density fiberglass cotton, and a transparent window is set on the box door to observe the changes in the indoor samples.
5. The observation window is made of multi-layer insulated tempered glass and has a laminated conductive film on the inside
6. The humidity is humidified by stainless steel boiler steam, with PT100 and wet cloth sensing for fast response control. At the same time, the problem of water freezing affecting temperature during low-temperature testing of shallow water humidifiers is eliminated. The mixing system adopts a long axis fan motor to ensure uniform and stable temperature and humidity in the laboratory.
7. A double-layer high-temperature resistant high tension sealing strip is used between the door and the box, and the test hole (on the left side of the machine) can be used for external testing power or signal lines (the aperture or number of holes can be determined according to customer instructions).
8. The refrigeration system of the equipment is installed at the bottom, and the compressor adopts the French Taikang brand to ensure refrigeration efficiency and reliability. The refrigerant is environmentally friendly.
9. The bottom of the machine is equipped with fixed PU movable wheels, which can easily move the machine to the * * position and then fix the casters.

3、 Control System for High and Low Temperature Damp Heat Test Chamber

1. High and low temperature wet heat testing equipment generally uses liquid crystal display programmable temperature controllers and temperature and humidity control instruments;
2. Intelligent digital PID microcomputer temperature control instrument;
3. Thin film buttons, touch settings, digital and direct display;
4. The humidity is directly displayed as a percentage, and the temperature sensor uses a PT100 platinum resistance tester.
5. The temperature control adopts the thermal balance temperature adjustment method.
6. The Korean LCD display programmable temperature controller can be used for program testing, with multiple sets and segments of programming operations, optional settings for fixed values and programs, and the ability to set time arbitrarily.
7. The main electrical components of the equipment, such as circuit breakers, AC contactors, and small relays, are all made of Schneider brand, while other electrical accessories are made in China.
