Applications
→The cryogenic unit for impact test of model CDW-60 is the newest compressor cooling equipment researched and developed by the company in accordance with the requirement for hypothermia apparatus according to GB/T229-2007 Metallic materials—Charpy pendulum impact test method (substitute GB/T229-1994 Metallic--Charpy notch impact test method).
→This equipment adopts cascade compressor cooling technology and thermal equilibrium principle and circulative mixing method to obtain the natural uniform cooling and constant temperature for the sample which can completely satisfy all items of temperature control indicators specified in the national standard GB/T229-2007.
→The operation of the equipment is simple and convenient with high working efficiency. It is the most ideal equipment for cooling and temperature keeping of the sample in low-temperature impact test of metals. It also can be used for other low temperature detection and test work.
