Flexible control: The system can perform automatic cycle lifting or manual selective impact, and can set three zone impact and start of cold and hot impact
Fast conversion: High and low temperature conversion time: within 10 seconds (other requirements to be agreed upon)
Fast cooling: The cooling adopts a binary freezing system, which has a fast cooling effect. The cooling method is water-cooled
Long term impact: When subjected to high or low temperature impact, the maximum time can reach 999H and the maximum cycle time can reach 9999 times
Food National Army Standards: Implementation of Standards and Test Methods: GJB150.5, GJB360.7, GB/2423.22
Product features
※ Adopting fully automatic PID control with high precision and can save 30% electricity,
The two boxes of equipment are divided into two parts: high temperature zone and low temperature zone. The test product is placed in a basket, and during impact, the basket moves the test product into the high temperature zone or low temperature zone for balancing. The test product is dynamic and equipped with a door opening safety system.
※ Adopting a touch based graphic control interface, the operating cylinder is easy to operate.
※ The impact method applies the wind path switching method to import the temperature into the testing area for cold and hot impact testing.
When subjected to high or low temperature shock, the maximum time can reach 999H and the maximum cycle cycle can reach 9999 times.
The system can be used for automatic cycling or manual selective shock, and can be set to start the secondary cold and hot shock.
※ The cooling adopts a binary freezing system, which has a fast cooling effect.
※ Hanging basket conversion time: within 10 seconds (other requirements to be agreed upon)
※ Implement the standard and test method: GJB150.5 temperature shock test; GJB360.7 temperature shock test; GB/2423.22
