Overview
BENTING CBGDW-100L low/high temperature test chamber is a professional Environmental performance equipment. It adopts cold plate paint outer box and mirror stainless steel inner wall, and is equipped with fiberglass insulation material. The box is equipped with a single-open hinged door, observation window, lighting lamp and anti-condensation electric heating device. The control system integrates a display screen, U disk interface and RS232 communication interface, which supports automatic adjustment of refrigeration operation and energy-saving working conditions.
Features
1. Enclosure Material is cold plate paint
2. The inner wall material is good mirror stainless steel plate
3, the box insulation material is fiberglass
4, single open hinged door with observation window, lighting and window frame/door frame anti-condensation electric heating device
5. The control panel includes a controller display screen, a U disk interface, an RS232 computer communication interface, a power switch, a status indicator, and a sound and light alarm device
6. The unit includes refrigeration unit, water tray, drain hole, condenser fan, condenser inlet trend and supply water tank
7. The power distribution system includes IO board, machine tool transformer, ballast, intermediate relay, solid state relay, AC contactor, thermal relay, fuse, undercurrent relay and air switch
8. The control system automatically adjusts the operation of the refrigerator according to the test conditions to save energy
9, evaporator cooling capacity driven by the control system solenoid valve switch
Principle
The test chamber automatically adjusts the operation of the refrigerator through the control system. The binary cascade cooling method is used in the range of -40 ° C to -70 ° C, and the evaporator cooling capacity is switched by the solenoid valve. The temperature control is based on the comparison of the display value of the controller with the measured value at the center point to ensure that the Temperature Fluctuation ≤ 0.5 ° C, the error ≤ +/-1 ° C and the uniformity ≤ 2.0 ° C.
Applications
Electronic product testing, material research, industrial inspection
Steps
1. Turn on the power switch
2. Set the test temperature range through the controller
3. Start the automatic operation of the refrigeration system
4. Monitoring status indicators and alarm devices
5. Turn off the equipment after the test is completed
Notice
• Prohibit testing of products that may produce flammable, explosive, volatile, highly toxic, corrosive, and radioactive substances
• Ensure that the equipment is used within the rated parameters
• Regularly inspect the power distribution system and unit components
• Follow the requirements of the rise and fall rate under nonlinear no-load conditions
