Jiangsu High and Low Temperature Damp Heat Test Chambercontrol system

1. The control part of the equipment is designed on the right side of the device, with temperature controllers, control switches, etc. distributed, making it easy to operate, simple, and maintain.

2. The temperature controller adopts the Korean SP790 or TEMP880 color touch intelligent programmable temperature controller, which is easy to edit and operate on the screen.

3. Chinese and English LCD display LCD touch panel, face-to-face input data, temperature programmable, curve display, set value/display value curve.

4. Multiple sets of PID control functions, precise monitoring functions, and displayed in the form of data on the screen.

5. It has the function of automatic calculation, which can immediately correct the temperature and humidity change conditions, making temperature and humidity control more accurate and stable.

6. The controller has an automatic screen saver function, which better protects the LCD screen and prolongs its lifespan under long-term operation.

7. It has a capacity of 10 programs, 100 segments per group, and 999 steps per segment that can be cycled. The maximum value for each segment is set to 99h59min.

8. Accuracy: 0.1, Resolution: ± 0.1 ℃, Temperature Sensor: PT100 Platinum Resistance Tester.

9. Control method: Thermal balance temperature regulation method.

10. The main components of the electrical control are all imported (Schneider) components, which better control the temperature.

11. The temperature control adopts the P.I.D+S.S.R system for coordinated control of the same channel.

12. After inputting the data and experimental conditions, the controller has a screen lock function to avoid manual touch and shutdown.

13. Equipped with RS-232 or RS-485 remote communication interface, it can be programmed on a computer to monitor the testing process and perform functions such as automatic power on/off.

Material:

1. The design of the shape: circular arc shape and surface spray treatment, high-quality appearance, more clean and beautiful.

2. The inner liner of the box is made of high-grade (SUS304) stainless steel plate.

3. The outer shell of the box is processed and formed using high-quality A3 steel plate CNC machine tools, with a beautiful and elegant appearance. The surface of the shell is treated with spray coating.

4. The temperature circulation system adopts a temperature resistant and low-noise air conditioning fan motor, and a high and low temperature resistant multi blade centrifugal fan wheel to achieve strong convection and vertical diffusion circulation.

5. A double-layer high temperature resistant sealing strip is used between the door and the box to ensure the sealing of the testing area. The door frame heating system ensures no frost or condensation outside the box, and a non reactive door handle is used for easier operation.

6. The insulation material is high-density glass fiber cotton, with a thickness of 100mm/120mm, to ensure a balanced and stable temperature in the laboratory.

7. The observation window is made of multi-layer hollow tempered glass and equipped with lighting fixtures. The inner laminated conductive film has the advantages of transparency, heat insulation, and is not prone to steam frosting, allowing for clear observation of the test process.

8. On the left side of the box, there is a test hole with a diameter of 25mm or 50mm, which can be used for external testing power or signal lines (the increase in aperture or number of holes needs to be explained).

9. The bottom of the high and low temperature alternating test box adopts high-quality fixed PU movable wheels for easy movement.

10. The indoor sample rack and other accessories are made of SUS304 stainless steel material.

Refrigeration and heating system:

1. The refrigeration system of the equipment is installed at the bottom, and the compressor adopts the French imported Taikang brand.

2. Condensation method: forced air cooling.

3. Cooling method: single (double) mechanism cooling.

4. Refrigerant: Environmentally friendly.

5. All system pipelines undergo a 48 hour leak detection test with ventilation and pressurization.

6. The heating and cooling system is independent.

7. Internal spiral refrigerant copper tube, slope evaporator.

8. Dehumidification adopts the evaporator coil dew point temperature laminar contact dehumidification method.

9. The solenoid valve, oil separator, drying filter, repair valve, refrigerant flow window, and storage tank are all imported original parts.

10. Heating uses far-infrared nickel alloy high-speed heating wire.

11. High temperature and low temperature are independent systems that do not affect each other.
