Impact Specimen Cryostat - ASI-DWC-Series

Impact Specimen Cryostat - ASI-DWC-Series

INTRODUCTION
DWC-series impact sample cryogenic tank is the latest compressor refrigeration equipment
developed by our company in accordance with the requirements for cryogenic devices in
GB/T229-2007 "Metal Charpy Notch Impact Test Method". This equipment adopts cascade
compressor refrigeration technology, utilizes the principle of heat balance and circulating
stirring method to achieve automatic uniform cooling and constant temperature of the
sample, which can fully meet the various temperature control indicators specified in the
national standard GB/T229-2007. This equipment is simple and convenient to operate and
has high working efficieney. It is the most ideal sample cooling and heat preservation
equipment in the metal low-temperature impact test. At the same time, it can also be
used for other low temperature detection and test work.
