This cold and hot impact test chamber is divided into three box and two box types based on test requirements and testing standards. The difference lies in the test method and internal structure. The three box type is divided into a cold storage chamber and a laboratory, and the product is placed in the laboratory during testing. The two box type is divided into a high temperature chamber and a low temperature chamber, which are driven by an electric motor to achieve high and low temperature. The product is placed in the basket and moves with the basket.

Introduction to Features


1： The quality advantage of the cold and hot impact testing machine is that the main core components are made from international major brands such as France Taikang, Japan's Lugong/Hequan/Mitsubishi, Schneider, America's Kuaida/DuPont Refrigerant, Denmark (DANFOSS), Sweden (AlfaLaval), and other accessories. If false, a penalty of ten will be imposed to ensure the normal and efficient operation of the high and low temperature impact testing box. Compared to other peers: using domestically produced parts or using counterfeit parts as brand accessories, shipping to customers is completely inconsistent with what is said, and the quality is greatly discounted. 2： Equipment technical advantages


1. Adopting a 7 "TFT true color LCD touch screen, it is larger, more intuitive, easy to operate, stable to operate, and more energy-efficient than other screens.
2. The evaporator adopts a water immersion leak detection method, which thoroughly checks the leak and ensures the stable operation of the equipment.
3. Adopting modular refrigeration units ensures manufacturing quality and is very convenient for maintenance and replacement.
4. Adopting a highly uniform positive pressure air duct system with high temperature uniformity.
5. Adopting the latest automatic defrosting technology to shorten the defrosting time and test the use of equipment. Efficiency has greatly increased.
6. It has multiple safety protection measures, fault alarm display, and functional display of fault causes and troubleshooting methods. 3： Energy saving advantages of the three box cold and hot impact testing machine
The three box cold and hot impact test chamber adopts a self-developed control system with high accuracy, stable and simple operation. The controller abandons the fixed mode of controllers such as Japan and South Korea, and adopts the latest fuzzy calculation technology to automatically analyze the load capacity and reasonably adjust the refrigerant flow rate, making the equipment energy-saving up to 20%.
