3 Box Type Cold And HotChamber

3 Box Type Cold And HotChamber

Applied range：

Three box is hot and cold impact test box according to user requirements design and manufacture, is suitable for the aviation, aerospace, military industry, ships, electrical and electronic products such as the machine and parts of high and low temperature impact test and high temperature or low temperature storage and test environment.For the user to accelerate the test of the whole machine (or parts), electrical apparatus, instrument, material, coating, coating and so on, so as to evaluate the test behavior of the test product or test.

 Performance characteristics：

1. The equipment is divided into high temperature box, low temperature box, test box of three parts, adopt unique thermal structures and heat storage effect, perfectly still, the object under test in testing the application of cold and hot wind path switching to cold, hot hot and cold impact test temperature import test area.

2. Use the most advanced measuring device, large color LCD controller USES a human-machine touch dialog type LCD human-machine interface controller, the operation is simple, learning easy, stable and reliable, the English display the complete system operation conditions, implement and setting process curve.

3. 96 independent setting test specification, impact time 999 hours 59 minutes, cycle 1 ~ 999 times can be set, which can realize automatic machine operation, the maximum extent, automation, reduce workload, operating personnel can be run automatically start and stop work at any time;

4. A 50mm diameter test hole is provided on the left side of the box, which can be used to test parts of power load wiring.

5. Can the independent set high temperature, low temperature and hot and cold impact the function of three different conditions, and perform in cold and hot shock condition, can choose two slot or three slot and cold shock, thermal shock impact function, has the function of the high and low temperature testing machine.

6. Fully automatic, high-precision system circuit, any movement of any machine, complete with P.L.C lock processing, all adopt P.I.D automatic calculation control, and the temperature control precision is high.

7. Advanced scientific air circulation design, keeping indoor temperature even and avoiding any dead Angle;Complete safety protection device, avoid any potential safety hazard, ensure the long-term reliability of the equipment.

8. Set cycle times and defrost times automatically (manual) defrost.The air outlet is controlled by the return air taste detector. The switch time of the damper is completed within 10 seconds, and the temperature recovery time of the cold and heat shock is completed within 3 minutes.

9. Operation state display and curve shows that an exception occurs, the screen instantly automatic display fault point and the reasons and provide troubleshooting methods, and found that the input power is not stable, with emergency stop device.

10. Refrigeration system using the cascade efficient cryogenic loop system design, refrigerating set by Europe and the United States imported compressor, and the use of ozone coefficient is zero (HFC) of green environmental protection refrigerants R507 R2 mixed refrigerants.

11. Super safe protection function: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, overtemperature protection, alarm sound warning, etc.

12. The inner and outer material of the box is made of stainless steel plate (SUS#304). The external material has a different outer box material to choose from :GB/T2423.1.2-2001, GJB150.5 GB10592-89.
