Product Characteristics

The first working process of a refrigerated air dryer starts with the intake of high-temperature, high-humidity compressed air generated by an air compressor. This wet compressed air first enters the dryer's air inlet port and flows directly into the pre-filter component, which is equipped with a high-density filter element. The pre-filter's main task is to remove large solid impurities such as dust, metal chips, rust particles, and oil mist droplets with larger diameters from the compressed air, preventing these contaminants from entering the subsequent refrigeration system and heat exchanger channels, which could cause blockages, corrosion, or reduced heat exchange efficiency. After passing through the pre-filter, the initially purified wet air continues to move forward along the air pipeline, preparing to enter the pre-cooling heat exchange stage, and this step ensures that the follow-up core refrigeration and dehumidification modules can operate in a clean air environment, extending the service life of key components and stabilizing the overall dehumidification effect of the dryer.

 

Working Principle

The amount of water vapor in the compressed air is determined by the temperature of the compressed air: under the condition that the pressure of the compressed air is basically unchanged, reducing the temperature of the compressed air can reduce the content of water vapor in the compressed air, and the excess water vapor will condense into liquid.

Our official after-sales team provides professional on-site installation and commissioning service for every refrigerated air dryer purchased from us. Experienced engineers will arrive at the customer's workplace at an agreed time to conduct a full inspection of the installation environment, including power supply stability, air pipeline layout, ventilation conditions, and space distance to ensure compliance with operational safety standards. They will then complete the connection of air inlet and outlet pipes, refrigerant lines, drainage pipes, and electrical wiring in strict accordance with the operation manual. After physical installation, engineers will conduct power-on tests, system pressure checks, refrigerant cycle detection, and dew point calibration to ensure the dryer reaches rated performance. They will also train on-site operators on basic operation, daily inspection points, and safe usage rules, ensuring stable startup before leaving the site.
