A Refrigerant Air Dryer is a device used in compressed air systems to remove moisture from the air. Moisture can cause corrosion, freezing and damage to pneumatic tools, equipment and machinery, which is why Air Dryers are essential in maintaining air quality and prolonging the life of compressed air systems.
How it works:
- Compression – Compressed air enters the dryer, typically at high pressure.
- Cooling – The air passes through a heat exchanger, where it is cooled by refrigerant, usually R-134a or R-410a.
- Condensation – As the air cools, the moisture condenses into water droplets.
- Water Removal – The condensed water is separated from the air and collected in a moisture trap or drainage system.
- Reheating – The dried air is then reheated and released at the desired temperature and pressure.
Key Features:
- Energy-efficient: Refrigerant dryers consume energy mainly for cooling, making them relatively cost-effective compared to other types.
- Temperature-controlled: The cooling process is usually based on a set point temperature, ensuring consistent air quality.
- Compact: These dryers are often compact and can be installed directly within the compressed air system.
Applications:
- Automotive repair shops
- Manufacturing plants
- Pneumatic systems in factories
- Food and beverage industries (where clean, dry air is crucial)
Refrigerant Air Dryers are ideal for moderate to high flow applications where air temperatures do not fall below freezing, as they typically operate in the range of 35°F to 50°F (1.6°C to 10°C) for air output temperatures.
