Main application:
DWC series Impact specimen cryogenic tank is a special auxiliary refrigeration equipment for low temperature impact test, which can meet various temperature control indexes of low temperature device specified in GB/T229-2007 Metallic Materials -Charpy Notch Impact Test. It uses imported high-performance cascade compressor for refrigeration, and adopts SCM automatic control (temperature control, timing, and alarming), which is of high temperature control precision, fast refrigeration speed, safe and reliable, and simple to operate. DWC series Impact specimen cryogenic tank is ideal equipment of cooling and heat preservation for low temperature impact test specimen.
Performance features:
This equipment adopts the refrigeration technology of cascade compressor, the principle of heat balance, and the method of circular mixing to realize automatic uniform cooling and heat preservation for test specimen.Technical parameters:
