Product Description

DWC-40 -40~+30 degree Low Temperature Chamber for Cooling Impact Specimen 

  

1. Application
The machine is designed according to Charpy notch Impact Test Method for Metal Material, and adopts compressor cooling technology. It utilizes the heat balance principle and cycle stirring method to realize the constant temperature cooling to impact specimen with the reliable performance. Digital display, automatic control temperature, and it is the ideal equipment for cooling and keeping temperature to impact specimen.
 
2. Main component:
The machine obtains one compressor, heating unit, electronic control box , cooling tank, cooling medium circulation system, automatic warning device, etc.
 
Standards:ASTM, E23-02a, En10045, ISO83,GB/T229-2009 
 
3. Working principle:
Boot refrigeration switch, compressor begin to work, refrigeration system into formal working state. Refrigeration compressor continuous work, when close to the setting temperature, the heating device which is in the cooling bath began to scale with heat.  To balance redundant cold quantity produced by the refrigeration system, in order to achieve the purpose of constant temperature. Stirring can make cooling medium of the cooling  tank  continuously circulation, make the temperature uniform.
 
4. Features:
4.1Imported compressor, DANFUS valve, imported evaporation-condensation machine;
4.2Controlled by intelligent instrument, digital presentation temperature value, automatic control temperature, automatic time and alarm.
4.3high security, refrigerate fast, large volume
