Main functions:
3 Boxes Cold and Hot Alternating Thermal Shock Tester is used to test the bad influence of the static state sample in the high and low temperature changes rapidly environment. Commonly used in electronic parts, auto parts and high-tech products, etc; and need to harsh environmental conditions test and high tolerance requirements inspection.
Main Feature:
1. Air-cooled hot and cold impact test chamber easy to operation, reliable in performance. Good appearance, reasonable structure, advanced technology, fine material, ect.
2. Equipment is divided into high temperature box, low temperature box, test box of three parts, adopt unique thermal structures and heat storage effect,the sample is static when testing, guide into hot and cold air to test ozone by hot and cold switching road to achieve hot and cold temperature impact purpose.
3. Use the most advanced measuring device, controller is large touch color LCD, easy to operate, reliabilty, curve of system operation conditions, implement and setting program can be show by Chinese and English.
4. 96 test specification set independently, impacting time is 999 hours and 59min, cycle time 1~999 times can be set. Can realize refrigerating machine automatic operation, reduce the operating personnel workload, can run automatically and stop work at any time.
5. There is 50mm test hole on the left side, to plus power supply load wiring test components.
6. Can independently set high temperature, low temperature, and the function of cold and hot shock in three different conditions.
7. Can be used as high temperature box or low temperature box, as high temperature machine, low temperature machine and hot -cold impact testing machine.
8. Have fully automatic, high precision system circuit, P.L.C lock handle all parts working, adopt the P.I.D control automatic calculation, high temperature control precision.
9. Advanced air circulation loop design of science, to make inner temperature uniformity, avoid any corner. Complete security protection device, to avoid any possible security hidden danger, ensure long-term reliability of the equipment.
10. Can set cycle-index and defrost the number, automatic or manual defrost.
11. Air outlet and air return vent controlled by sensors detection, throttle body switch time less than 10s, cold and hot shock temperature recover time less than 15min.
12. When running the state and curve display, if there any unusual condition, screen instantly automatic display failure point,the reason and provide troubleshooting methods. If the input power is not stable, the emergency stop device will protect the testing machine.
13. Refrigeration system using cascade cryogenic loop system design, frozen with Europe and the United States imported compressor, and use of ozone coefficient is zero (HFC) of green environmental protection refrigerants R507, R23.
14. Strong safety protection function:overload protection, power leakage protection, control circuit overload, short circuit protection, compressor protection, earthing protection, over temperature protection, alarm voice prompt and so on.
3-slot hot and cold impact testing machine specifications
Control method and characteristics:
Using low temperature and high temperature hot and cold storage storage tank, in accordance with the need to open damper, the hot and cold temperature in the storage tank to entrance test slot to achieve rapid temperature shock effect, Balance the thermostat control system(BTC)+special design air distribution system, use P.I.D way to control SSR, Make the system plus calories quantity of heat loss, thus the use of long-term stability.
