1. Function

CDW-30-type impact test low-temperature chamber is a supplemental equipment for impact test under low temperature to keep the specimen cooling or at a constant temperature.

2. Features

1. It adopts imported dual-compressor refrigeration technology, heat balance principle and loop mixing method；

2. It can achieve automatic uniform cooling and constant temperature for specimen;

3. It complies with the temperature control provisions of relevant national standards and GB/T 229-2007 “Metal Charpy Notch Impact Test Method”.

4. It can meet all requirements for specimen testing at low or ultra-low temperature with easy operation, reliable quality and high working efficiency. Besides, it can also be used for other low-temperature detection and testing.

5. There are also CDW-40, CDW-60, CDW-80, CDW-100, CDW-150, and CDW-19（liquid nitrogen） models to meet needs from different customers.

3. Application

CDW-30-type impact test low-temperature chamber, as the best low-temperature impact testing equipment, is widely used in many industries and areas including petrochemical industry, metallurgy, boiler and pressure vessels, steel plates, steel pipes, wind power generation, hardware, metal, casting, pumps, valves, solar energy, war industry, fasteners, diesel engines, electric power, iron towers, railways, shipbuilding, machinery manufacturing, automotive industry, aerospace industry, physical and chemical laboratory and scientific research.
