1. Sturdy and durable structure: The inner and outer boxes are made of stainless steel plate (SUS #304) and powder paint, and the thermal insulation layer is fire-resistant and fireproof PU + thermal insulation Glass cotton. 2. Humanized design: equipped with high-luminance energy-saving lighting, five-layer reinforced Glass observation window, electric heating and sweat-proof device, movable adjustable grid frame and low-noise (less than 65 decibels) design. 3. Precise temperature and humidity control: Adopt equilibrate Conditioning P.I.D + P.L.C + A.D + S.S.R system, temperature and humidity analysis capacity of 0.01 ℃/0.1% RH, control accuracy +/- 0.2 ℃/ +/- 2% RH. 4. High-efficiency refrigeration system: using French Taikang brand air-cooled Compressor and environmentally friendly refrigerant R404A, with intelligent expansion valve energy-saving design, standard models can achieve low humidity (60-80 ℃, 10% humidity) test. 5. Intelligent control system: equipped with 7-inch TFT true color TEMI1500 controller imported from Korea, supports touch operation, remote monitoring, program memory (100 groups of 6000 segments), data storage and Linear dispersion display. 6. Perfect safety protection: It has multiple fault detection and alarm functions such as leakage/surge protection, multiple over-temperature protection (including dynamic adjustment), water cut-off air burning protection, Compressor overcurrent and pressure protection, water tank water shortage protection, etc. 7. Convenient maintenance design: water and electricity separation, hidden water storage tank, water tank quick plug and unplug connector, waterway filtrate system and internal and external equilibrate pressure design, easy to add water, clean and maintain.
The device realizes temperature control through a vapor compression refrigeration cycle. The refrigerant enters the evaporator after being throttled by the expansion valve to absorb heat and evaporate, forming a low temperature and low pressure gas. After being compressed into a high temperature and high voltage gas by the Compressor, it is chilled down into a high voltage liquid in the condenser, and then throttled by the expansion valve to achieve cooling in this cycle. The temperature control adopts the equilibrated temperature regulation P.I.D + P.L.C + A.D + S.S.R system. The humidity control is realized by the stainless steel armored humidifier and the equilibrate humidification system. It is detected by the High Accuracy PT100 Platinum Resistance Sensor and precisely adjusted by the microcomputer controller to create and maintain the set temperature and humidity environment in the box.

Equipment preparation: Install the equipment in a stable location, connect the AC 380V three-phase five-wire power supply (voltage fluctuation does not exceed +/- 10%), connect the humidity water supply pipe (inlet pipe diameter 1/4 ", water pressure less than 0.5kg) and the drain pipe (diameter 1/2"). 2. Boot and Settings: Turn on the power, select the operating language (Chinese/English) through the 7-inch touch screen controller, and select the fixed-point or programmable control mode. 3. Program editing: If you need to run the program, enter the program setting interface, and use the memory function of the controller 100 group 6000 segments to set the required temperature and humidity Linear dispersion, time (0H1M~ 9999H59M) and cycle parameters. 4. Sample placement: Open the box door and place the test sample on the movable adjustable stainless steel grid plate rack, paying attention to leaving an appropriate space between the samples. 5. Run the test: After confirming that the settings are correct, start the test program. The device will run automatically, and the controller will display and store PV, SV Linear dispersion and data in real time. 6. Monitoring and recording: During the test, the status can be monitored and data downloaded through the controller screen or remote communication interface (RS232/RS485/USB). 7. End of the test: After the program is completed, the device will automatically stop, or stop manually. After the temperature in the box is close to the environment temperature, open the box door and take out the sample. 8. Shutdown and maintenance: Power off the equipment, clean it if necessary, and drain or clean the water tank.
* power requirements: AC 380V 50HZ three-phase five-wire power supply must be used, and the voltage fluctuation should not exceed +/- 10% of the rated value. * Installation environment: The equipment should be placed on a well-ventilated, stable ground away from heat sources and flammable and explosive materials to ensure that there is enough heat dissipation space around the condenser (air cooling). * Water requirements: Humidity water needs to be purified water or tap water treated by the equipment's own RO reverse osmosis system to prevent scale blockage. Make sure that the water pressure is lower than 0.5kg when automatically replenishing water. Sample placement: When placing test samples, the total load should not exceed the allowable range of the equipment, and the air duct in the box should not be blocked to ensure uniform temperature and humidity. Operation monitoring: During the test, attention should be paid to the controller display and alarm information. If there is an alarm such as overtemperature or water shortage, it should be checked immediately. * Safe operation: When the equipment is running, do not open the box door frequently, so as not to affect the test accuracy and equipment life. Pay attention to the internal temperature before opening the door to prevent burns or frostbite. * Regular maintenance: regularly check the waterway filtrating system, clean the humidifier and water tank, check the operation status of key components such as the Compressor, and ensure the performance of the equipment. Fault handling: If the equipment malfunctions and alarms, please refer to the controller prompt information or fault records for preliminary judgment. Non-professionals should not disassemble and repair without authorization, and should contact professional technicians. * Transportation and storage: The equipment should be handled with care to avoid violent vibration. When not in use for a long time, the water in the tank should be drained and regularly powered on for maintenance.
