Supports customization with a processing capacity of up to 15900 CFM (cubic feet per minute).
Low pressure loss: The precooler is a newly designed annular pipe structure, with three times more pipes than the traditional precooler. The sufficient cross-sectional area of compressed air further reduces the pressure difference, and the pressure loss of the whole machine is less than 0.1 bar;
Frequency conversion energy saving: Brand inverter, frequency conversion range 30Hz~90Hz, by changing the electromechanical frequency of the dryer to match the actual working conditions;
Intelligent control: Standard PLC and touch screen, intelligently control the compressor cooling capacity output by sensing the evaporation load, ensure the machine runs in the best state, and standard RS-485 communication interface.
The Frequency Conversion Refrigerated Air Dryer is designed to deliver stable, energy-efficient moisture removal for industrial compressed air systems. By using variable-speed frequency conversion control, the refrigeration system automatically adjusts its operating output according to the actual air-load demand. This helps reduce energy consumption while maintaining a consistent outlet dew point.
The dryer features a centrally mounted evaporator core within the heat-exchange assembly, which reduces cooling loss and improves overall heat-transfer efficiency. As a result, more cooling capacity is directed to the pre-cooler, allowing faster temperature reduction and more effective moisture condensation.
A newly designed integrated water separator, equipped with 304 stainless-steel wire mesh, provides highly efficient vapor-liquid separation. Condensed water is removed thoroughly from the compressed air stream, ensuring clean and dry air for downstream equipment and demanding production environments.
To ensure stable performance and reliable long-term operation, the Frequency Conversion Refrigerated Air Dryer should be used under the following recommended conditions:
For the best drying result, the dryer should be installed in a well-ventilated environment with stable inlet conditions. Proper pre-filtration is recommended to protect the internal heat-exchange system and maintain efficient condensate separation over long-term operation.
