Fully automatic low-temperature impact test chamber

Fully automatic low-temperature impact test chamberSuitable for the physical changes of electrical, electronic, and mechanical components, automation parts, communication products or components, chemical materials, hardware and plastics, LED, LCD optoelectronics, photovoltaics, lighting, semiconductor ceramics, and polymer materials. It tests the rapid and repeated resistance of materials to cold and hot temperatures, as well as the chemical changes or physical damage that occur when industrial products are in an environment of thermal expansion and contraction. It can confirm the quality of industrial products, from precision ICs to heavy machinery components, and can serve as a basis or reference for improving the quality of many products in the industrial industry. In order to assess the adaptability of the product or evaluate the behavior of the tested product. It is an important testing method throughout the entire process of new product development, prototype testing, and product qualification testing.

Fully automatic low-temperature impact test chamberAdvantage:

1. It has a disk USB recording function and does not require a recorder;

2. Flow calculation control of refrigerant servo valve, saving 30% electricity;

3. In the low-temperature working state, the heater does not participate in the operation. The flow rate and direction of the refrigerant in the refrigeration unit are controlled and adjusted through PWM technology, and the three-way flow rate of the refrigeration pipeline, cold bypass pipeline, and hot bypass pipeline is adjusted to achieve automatic constant temperature in the working room. This method can achieve a 40% reduction in energy consumption under low temperature conditions

4. The control system adopts a color touch screen controller with high control degree and long service life. It adopts a large 7-inch LCD display screen, which has the characteristics of high clarity and sensitive touch screen response.

5. The automatic defrosting technology adopted by Aipei Technology shortens the defrosting time and greatly increases the efficiency of the thermal shock test chamber. Most cold and hot shock test chambers usually start to frost after a period of operation, and the defrosting time is very long, resulting in low efficiency. Some of them use automatic defrosting technology, which requires manual defrosting before testing, resulting in poor efficiency.

6. It has multiple safety protection measures, fault alarm display, and functional display of fault causes and troubleshooting methods. The voltage protection module has a withstand voltage of up to 500V and is not afraid of equipment burning when connected. Can effectively control and manage the amount of refrigerant. Automatic safety protection switch, with high sensitivity, can detect any state, cut off protection and alarm notification in a short time, ensuring the safety of personnel and machines. Independent temperature rise and fall, BTHC constant temperature control method. The air circulation system avoids dead corners of airflow inside the box and improves the uniformity of product temperature.
