GDJW-010 High and Low Temperature Alternating Test Chamber

Product Usage: This product is a testing equipment used in the fields of aviation, automotive, home appliances, scientific research, etc. It is used to test and determine the parameters and performance of electrical, electronic, and other products and materials after high temperature, low temperature, or constant temperature environmental changes.

1、 Main technical indicators

2、 Structure Introduction:
1. The outer shell is processed and formed using (t=1.2mm) A3 steel plate CNC machine tool, and the surface of the outer shell is sprayed with plastic for a smoother and more beautiful appearance;
2. The inner liner adopts imported high-grade stainless steel (SUS304) mirror panel;
3. High density glass fiber cotton is selected as the insulation material The insulation thickness is 80mm;
4. Temperature cycle system: using a specially designed low-noise long axis fan motor with stainless steel multi blade impellers that are resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation;
5. Double layer high tensile sealing strips with high temperature resistance are used between the door and the box to ensure the sealing of the testing area;
6. Using non reactive door handles makes operation easier;
7. The bottom of the machine adopts high-quality fixed PU movable wheels;
8. The observation window adopts multi-layer insulated tempered glass, and the inner side is coated with laminated conductive film for heating and defrosting (clearly observe the test process);
9. The test hole (on the left side of the machine) can be used for external testing power or signal lines (the aperture or number of holes needs to be increased and indicated);

3、 Heating system:
1. Adopting far-infrared nickel chromium alloy high-speed heating electric heater;
2. High temperature independent system, does not affect low-temperature and high-temperature tests;
3. The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency;

4、 Control system:
1. The temperature control instrument adopts a "7.0-inch color touch screen" programmable microcomputer PID control SSR output operation, and the number of cycles can be set;
2. Accuracy: 0.1 ℃ (display range);
3. Resolution: ± 0.1 ℃;
4. Temperature sensor: PT100 platinum resistance thermometer;
5. Control mode: thermal balance temperature and humidity control mode; All electrical appliances use Schneider series products;
6. The temperature control adopts the P.I.D+S.S.R system for coordinated control of the same channel;
7. It has the function of automatic conversion, which can immediately correct the temperature change conditions, making temperature and humidity control more accurate and stable;
8. The return air outlet of this test chamber is equipped with an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator and cause ice blockage);

5、 Refrigeration system:
1. Compressor: Fully enclosed original French Taikang;
2. Cooling method: single (double) mechanism cooling;
3. Condensation method: forced air cooling;
4. Refrigerant: R404A, R23 (environmentally friendly);
5. All system pipelines undergo a 48 hour leak detection test with ventilation and pressurization;
6. Heating and cooling system * independent;
7. Internal spiral refrigerant copper tube;
8. Slope evaporator;
9. The dry filter, refrigerant flow window, repair valve, oil separator, solenoid valve, and storage tank are all imported original parts;
10. Dehumidification system: using evaporator coil dew point temperature laminar contact dehumidification method;
11. Start R404A and R23 during cooling, and only start R404A during dehumidification (energy-saving and consumption reducing);

6、 Protection system:
1. Fan overheating protection;
2. Overall equipment under phase/reverse phase protection;
3. Overload protection for refrigeration system;
4. Refrigeration system overpressure protection;
5. Overall equipment timing;
6. Overheating of water pump, overcurrent protection;
7. Other protections include leakage, water shortage, operation indication, automatic shutdown after fault alarm, etc;

7、 Equipment usage conditions;
1. Environmental temperature: 5 ℃ to+28 ℃ (average temperature within 24 hours ≤ 28 ℃);
2. Environmental humidity: ≤ 85%;
3. The machine should be placed 80 centimeters in front, back, left, and right, and no objects should be placed;

8、 Compliant with relevant standards such as GB/T10592-2008, GB/T2423.1-2008, GB/T2423.2-2008, GB/T2423.4-2008, etc;

Free home delivery, after the installation and debugging of the equipment is completed, relevant technical personnel will receive free basic operation training at the user's site, with no limit on the number of people.
