Features:
1. The three box structure has fast conversion speed and short recovery time.
2. Easy to operate, reasonable air duct circulation system, uniform temperature distribution.
3. Chinese interface LCD display program controller.
4. Powerful refrigeration inlet compressor, fast cooling speed.
5. Complete and reliable safety devices.
6. High reliability design, suitable for continuous testing for more than 24 hours.
Control methods and features:
Using low-temperature and high-temperature thermal storage tanks, open DAPER according to the action needs to achieve rapid impact effect; The Balanced Temperature Control System (BTC) controls SSR in a P.I.D. manner to ensure that the heating amount of the system is equal to the heat loss, thus enabling long-term stable use.
Structural characteristics:
The product has a beautiful appearance, reasonable structure, advanced technology, and carefully selected materials.
The equipment is divided into three parts: a high temperature chamber, a low temperature chamber, and a testing chamber. It adopts a unique thermal insulation structure and thermal storage effect. During the test, the test object is completely stationary, and the cold and hot air path switching method is applied to introduce the cold and hot temperatures into the testing area to achieve the purpose of cold and hot shock testing.
Adopting a touch sensitive liquid crystal (LCD) display human-machine interface dedicated controller, advanced measuring device, simple operation, easy learning, stable and reliable, displaying complete system operation status, execution and program setting curves in both Chinese and English.
96 test specifications are independently set, with an impact time of 999 hours and 59 minutes, and a cycle period of 1-999 times that can be set. The refrigeration machine can automatically operate, greatly achieving automation and reducing the workload of operators. It can automatically start and stop working at any time.
There is one 50mm test hole on the left side of the box, which can be used for external power load wiring and testing components.
✰ It can independently set the functions of high temperature, low temperature, and thermal shock under three different conditions. When performing thermal shock conditions, it can choose two slot or three slot and cold shock and hot shock functions, and has the function of a high and low temperature testing machine.
✰ Equipped with fully automatic, high-precision system circuits, any component action, fully P.L.C locking processing, all using P.I.D automatic calculation control, high temperature control accuracy.
Unique air circulation design ensures uniform indoor temperature and avoids any dead corners; A complete safety protection device avoids any potential safety hazards and ensures the long-term reliability of the equipment.
✰ The number of cycles and defrosting times can be set for automatic (manual) defrosting.
The air outlet is detected and controlled by the return air outlet sensor. The switching time of the air door mechanism is completed within 10 seconds, and the recovery time of the cold and hot shock temperature is completed within 5 minutes.
A comprehensive safety protection device that automatically displays the fault point and cause on the screen in case of abnormal conditions, provides troubleshooting methods, and has an emergency stop device when unstable input power is detected.
The refrigeration system adopts a binary high-efficiency low-temperature circuit system design, uses German imported compressors, and uses green and environmentally friendly (HFC) refrigerants R507 and R23 with zero ozone coefficient.
✰ Super strong safety protection function: power overload protection, leakage protection, control circuit overload, short circuit protection, compressor protection, grounding protection, over temperature protection, alarm sound prompt, etc.
The material inside and outside the box is made of stainless steel plate (SUS # 304)
Performance characteristics:
Pneumatic valves are easy to open, ensuring airtightness and thermal protection;
The test slot is completely stationary, and load wiring can be applied through the test hole;
Energy storage methods can prevent occupational injuries to users; (Note: The exhaust gas generated by liquid gas, when inhaled into the lungs, reduces the amount of oxygen in the lungs, leading to work fatigue, lack of concentration, etc.)
Adopting a touch sensitive color LCD display human-machine interface controller, it is easy to operate and learn;
High temperature control accuracy, all using PID automatic calculation control;
✰ You can choose the starting position and start cycling at high or low temperatures;
✰ Equipped with a pre start function;
✰ Can set the number of cycles and automatic defrosting;
✰ Movement status display;
✰ Explanation of abnormal or faulty display and troubleshooting methods;
Equipped with three color alarm indicator lights: green: normal operating status; Yellow: standby state Red: fault state.
