Product Description

Product applications:
Thermal Shock Resistance Test Equipment make it possible to automatically and repeatedly transfer a test item from a hot environment to a cold environment or from a cold environment to a hot environment. This process is defined as true thermal shock and it is different from thermal cycling, where the specimen is introduced into the chamber and the chamber temperature is then cycled. A true thermal shock chamber can achieve a 265'C temperature variation rapidly, while thermal cycling may take hours to ramp up or down.

   8. Cooling water temperature: circulating cooling water temperature: ≤ +30 ° C;
   9. Cooling water pressure: circulating cooling water supply pressure: 0.25MPa ~ 0.4MPa; cooling water piping system design and construction should ensure that the inlet pressure of the refrigerator is 0.25MPa ~ 0.4MPa at the rated flow; the refrigerator exits to the cooling tower The pressure drop is not more than 0.05 MPa;
   10. Flow rate: 7t/h, (if using the circulating chilled water of the air conditioning system, please pre-specify the user);
   11. Air source (compressed air): pressure: (5 ~ 7) kg / cm2; connecting pipe diameter: ∮ 8mm; flow: 0.1 cubic / min;
   12. Requirements for the storage environment: When the equipment is not working, the temperature of the environment should be kept within 0 °C ~ +45 °C. When the ambient temperature is lower than 0 °C, the water remaining in the equipment should be drained to prevent the water in the pipeline from freezing. Up the pipeline.
