Cdw-196t impact test cryometer dual system (compressor + liquid nitrogen refrigeration) system configuration is excellent, beautiful and durable, fast cooling, high temperature control accuracy, using advanced national patent technology, all stainless steel chassis, equipped with special liquid nitrogen tank. The compressor system uses imported cascade refrigeration compressor to provide you with an ideal impact test cryogenic device.
1、 Application and characteristics
Cdw-196t impact test cryometer dual-purpose dual system (compressor + liquid nitrogen refrigeration) is the latest compressor refrigeration equipment developed by our company according to the requirements of GB / t229-2007 "metallic materials Charpy pendulum impact test method" for cryogenic devices. The equipment adopts cascade compressor refrigeration technology and liquid nitrogen refrigeration technology, uses the heat balance principle and circulation stirring mode to achieve automatic uniform cooling and constant temperature of the sample, and can fully meet the temperature control indexes specified in the national standard gb229-07. It is the most convenient and efficient equipment for metal impact test. It can also be used for detection and other low temperature tests.
