DWC-60 Impact Test Low Temperature Chamber

The DWC-60 impact test low-temperature chamber is a newly developed compressor refrigeration equipment based on the requirements for low-temperature devices in GB229-94 "Metallic Charpy notch impact test method". This equipment adopts a cascade compressor refrigeration technology, utilizing the principle of thermal balance and circulating stirring to achieve automatic uniform cooling and constant temperature of the sample, fully meeting the temperature control indicators specified in the national standard GB229-94. This device is easy to operate and has high work efficiency, making it an ideal sample cooling and insulation equipment for metal low-temperature impact testing. It can also be used for other low-temperature detection and testing work.
