Two boxes of high and low temperature impact test chambers

XF/GDWCJ-500L

Product Usage

The two box high and low temperature impact test chamber is a testing equipment used in aviation, automotive, home appliances, scientific research and other fields to assess and determine the parameters and performance of electrical, electronic, automotive electrical, materials and other products after temperature environment impact changes during high and low temperature tests. It is suitable for use in schools, factories and other units.

Box structure:

It is processed and formed using CNC machine tools, with a beautiful and elegant appearance, and adopts a non reactive handle for easy operation.

The inner liner is made of imported stainless steel (SUS304) plate, and the outer liner is made of galvanized steel plate spray painted, which increases the appearance texture and cleanliness.

The large observation window is equipped with lighting to keep the inside of the box bright, and the tempered glass embedded in the heating body is used to clearly observe the condition inside the box.

Equipped with a test hole with a diameter of 50mm, it can be used for external testing power or signal lines

Control system:

Temperature control adopts imported touch screen and LCD display, which can display set parameters, running time, set curve, heating

Working status, PID parameter self-tuning function.

The programming of the control program adopts a human-machine dialogue method, which only requires setting the temperature to achieve automatic cooling and heating operation functions. The control system has a complete detection device that can automatically display detailed faults. Alarm, configured with 232 communication interface and running software, can be connected to a computer.

Refrigeration system:

The refrigeration system adopts a unit or binary low-temperature circuit system design.

Imported blog semi enclosed water-cooled compressor unit/original French "Taikang"/fully enclosed air-cooled cascade compression refrigeration method,

The dry filter, refrigerant flow window, repair valve, oil separator, solenoid valve, and storage tank are all imported original parts

Circulating system:

Temperature resistant and low-noise air conditioning motor Multi blade centrifugal wind turbine.

Using multi wing fans for air circulation can avoid any dead corners and ensure even temperature distribution in the testing area.

The design of circulating air outlet and return air ensures that the wind pressure and speed meet the testing standards, and can quickly stabilize the temperature at the moment of opening the door.

Heating, cooling, and system independence can improve efficiency, reduce testing costs, extend lifespan, and decrease failure rates.

Protection system:

Equipment overheating; Overall equipment under phase/reverse phase; Overall equipment overload; Refrigeration unit overpressure; Overall equipment timing;

Other protections include leakage, operation indication, automatic shutdown after fault alarm, etc.
