250 Nm³/Min Air Cooled Tube-Type Refrigerated Dryer with PLC Control System

Product Description

2m³ /  6m³  Tube-exchanger refrigerate air dryer

Based on advanced heat exchange technology, the Tube-Exchanger Refrigerated Air Dryer efficiently removes moisture from compressed air systems by utilizing a highly efficient tube-based heat exchanger design. This dryer ensures optimal performance through a countercurrent heat exchange process, which maximizes energy efficiency and operational stability. It features a high-efficiency gas-liquid separator with over 99% separation effectiveness, ensuring thorough removal of condensate and delivering consistently dry air with a reliable pressure dew point. The unit is engineered for smooth and automatic drainage, reducing maintenance requirements and enhancing the quality of your air supply. Suitable for a variety of operating conditions, the Tube-Exchanger Refrigerated Air Dryer offers a professional and energy-saving solution for maintaining clean, dry compressed air in industrial applications.

Working principle

   •  Compressed air first enters the precooler (20 or 21)for preliminary cooling,Then it flows into the regenerator (1) and undergoes heat exchange with the returned product gas, resulting in compression.The air further cools down. And discharge the condensed water outside the machine Afterwards, press The compressed air flows into the evaporator (2) and exchanges heat with the refrigerant, causing the compressed air to Further cooling to achieve the required dew point temperature.
   •  Compressed air passes through the precooler (21 or 20),
regenerator (1), and evaporator(2) After gradual cooling, the water vapor in the air condenses into liquid droplets, passing through the gas liquid The function of separator (3) is to separate liquid water.
   •  The dry cooling air passing through the separator (3) of the enterprise passes through the regenerator(1) Another process, which is heated up when leaving the dryer, reduces the air flow Relative humidity.
