Product application:
A split structure can be adopted, with the refrigeration unit and the box placed separately.high and low temperature test chamber is used for reliability testing under high and low temperature conditions.

It is applicable to components and materials in industries such as electronics and electrical engineering, automotive and motorcycles, aerospace, rubber and plastics, metals, shipbuilding and defense, as well as universities and research institutions, to evaluate their performance indicators under varying high and low temperature conditions.

Compliance with standards:
GB/T2423.1-2008
GB/T2423.2-2008

Chamber structure:
The chamber of the high and low temperature test chamber is processed by a CNC machine tool to form a shape that is aesthetically pleasing and elegant.

It also features a non-reaction handle for easy operation. The inner chamber is made of imported high-grade stainless steel (SUS304) mirror plate, while the outer chamber is made of A3 steel plate with spray plastic coating, which enhances the appearance and cleanliness.

The large observation window is equipped with a lighting lamp to keep the inside of the box bright. The use of an inlaid tempered glass in the heating element allows for a clear view of the internal conditions at any time.

The machine is mounted on high-quality fixed PU casters at the bottom. A test hole with a diameter of 50 mm is provided on the left side of the box, which can be used to connect external test power cables or signal lines.

Control system:
The temperature control of the high and low temperature test chamber uses a fully imported touch-button instrument, which is simple to operate and set up.

Once the data and test conditions are entered, the controller has a locking function to prevent accidental changes to the temperature values due to human touch.

It features a PID automatic calculation function, which can immediately correct temperature changes, making the temperature control more precise and stable.

The main components of the electrical control system use the imported well-known brand “Schneider” to better control the temperature. Optional features include a printer and computer connection.

Refrigeration system:
The refrigeration unit of the high and low temperature test chamber uses a fully enclosed compressor originally from France, specifically the “Tecumseh” brand.

It also features a drying filter from the United States by “Alco,” an oil separator from Taiwan by “Guan Ya,” and an electromagnetic valve from Italy by “Castel.”The refrigeration system is designed with a single-stage or two-stage low-temperature loop system.

A multi-blade fan is used for powerful air circulation, eliminating any dead zones and ensuring uniform temperature distribution within the test area.

The airflow design, including both supply and return air, meets the testing standards for air pressure and velocity, and allows for a quick temperature recovery when the door is opened.

The heating, cooling, and systems are completely independent, which enhances efficiency, reduces testing costs, extends service life, and lowers the failure rate.
