Cool Air Dehumidifier

Cool Air Dehumidifier GMJW Series utilize evaporator and condenser to process the air to reach the thermostat and dehumidifying. During the process, the heat of condensation is recycled, which is to compensate the heat lost when cooling and dehumidifying.

We provide the extra function of Cooling and make this series due to some industrial and commercial facilities need to provide an ideal environment for the well-being of certain products and for the comfort of customers and visitors. We have 4 types of Cooling dehumidifier for your choice: GMJW-7A, GMJW-10A, GMJW-15A and GMJW-20A. Combined with Refrigeration, heating and dehumidifying, our devices will meet various environment requirement and will let you control temperature and humidity freely.

And to provide sustainable and creative service, we are still innovated other types. Except for the standard ones, we also accept customized thermostat dehumidifier units in accordance with your specific requirement.

Principle of Cool Air Dehumidifer

The whole process contains 3 main connected systems: Refrigerant recycling system, Air recycling system and Electrical automatic control system.

  • Refrigerant cycling system:The liquid refrigerant absorbs the heat in the air and starts to evaporate, thus making the relative temperature difference between the refrigerant and the air. When the liquid refrigerant comes into gaseous form, it is inhaled and condensed in compressor. Then the gaseous refrigerant absorbs heat in the condenser (air cool/water cool) into liquid. Through the throttling process of the expansion valve, it finally becomes liquid refrigerant with low temperature and low pressure. That is the recycling system of refrigerant.
  • Air recycling system:The air is sucked up into air outlet by the fan. It is transferred into the room where users needed through evaporator (Cooling and dehumidify), humidifier and electric heater (Heating). Then the transferred air mix with the air within the room comes back to the air outlet. That makes the recycling of air.
  • Electrical automatic control system:This system is made us of voltage and automatic control system separately. Voltage, in simple terms, supply electricity to the compressor, fan, electric heater. Automatic control system can be divided into temperature control, humidity control and malfunction protection.

Application of Cool Air Dehumidifier

National defense engineering, Civil air defense works,  precision instrument room, Tobacco, Petrochemical industry, Subway station, Aerospace, Purification Project, Laboratory, Computer room, Archives, Food workshops, Pharmaceutical or firm workshops, Special Glass Production, Wood and other occasions needs the control of humidity and temperature.
