Overview of 3-in-1 Plate Heat Exchange Refrigerated Air Dryer
The 3-in-1 plate heat exchange refrigerated air dryer integrates pre-cooling, refrigeration, and condensation processes into a single compact unit. Beyond basic operation, users often want to understand energy efficiency, stable dew point performance, and suitability for various industrial applications.
Design Principles and Advantages
Integrated Plate Heat Exchange
The 3-in-1 design ensures effective heat transfer, reduces energy consumption, and maintains a stable dew point between 2–10°C.
High Efficiency Condensate Removal
The dryer features advanced vapor-liquid separation, ensuring condensate is completely removed to deliver clean, dry compressed air for sensitive equipment.
Flexible Cooling Options
Air-cooled or water-cooled options provide adaptability for different plant environments, maintaining efficiency even under high ambient temperatures.
Low Pressure Loss
The system is engineered to minimize pressure drop (<0.01 MPa under full load), improving compressor efficiency and reducing operational costs.
Operating Conditions
Applicable Fluids: Compressed air, non-corrosive air
Rated Inlet Pressure: 0.7 MPa (0.6–1.0 MPa, other pressures customizable)
Rated Air Inlet Temperature: 45°C (≤60°C limit)
Pressure Loss Under Full Load: <0.01 MPa
Outlet Dew Point: 2–10°C
Rated Ambient Temperature: 35°C (usable 2–45°C)
Cooling Method: Air-cooled or water-cooled optional

2. Low pressure drop: the pressure loss of the whole machine is less than0.015MPa,which is lower than the national standard:
3. Low dew point: under standard working conditions, the pressure dew point isas low as 2~10'C, and the electronic bypass valve is adopted, making thesystem more stable.
