CDW-30 Pendulum Impact Testing Low-temperature Chamber(Low-temperature tank)

Usage and Characteristics
CDW Series Pendulum Impact Testing Low Temperature Meter is newly researched and developed compressor refrigeration equipment according to requirement of low temperature device in GB/T 229-2007. This device includes compressor refrigeration and liquid nitrogen refrigeration. Compressor cooling takes advantage of the principle of heat balance and loop mixing method to achieve automatic uniform cooling and constant temperature for samples. The refrigeration mode of ultra-low temperature equipment adopts mainly liquid nitrogen refrigeration, using the performance of ultra-low temperature of liquid nitrogen, based on heat balance principle, to achieve automatic uniform cooling. The temperature indicator can meet the national standard completely. It can also can satisfy American standards and European standards, like ASTM,E23-02a,EN10045, ISO148,ISO83 and other international relative standards.

Advantages
1. Imported compressor, DANFUS valve, imported evaporation-condensation machine;
2. Controlled by intelligent temperature control instrument, digital presentation temperature value, automatic control temperature, automatic time and alarm;
3. Easy to operate, prompt refrigerating speed, capacious working space, high-precision control temperature
4. Make sample fully soaked inside the flowing liquid,sample can be fully cooling and temperature uniformity.
5. The equipment only needs AC220V power source,which is energy-saving and environmental protection.
