Refrigerated Air Dryer
Model: RFD Series
1. Product Overview
A refrigerated air dryer is core compressed-air post-treatment equipment: it cools compressed air to a pressure dew point of 2–10°C so that water vapour condenses and is drained off. With low operating cost, simple maintenance, and large capacity, it is the most widely used dryer in compressed-air systems.
Key Features
- Pressure dew point of 2–10°C
- Capacity from 0.5 to 100 m³/min
- Low operating cost
- Stainless-steel heat exchanger
- Intelligent control with automatic drain
- Bypass-valve design for stable operation
