Why a Refrigerated Compressed Air Dryer Is Essential
Moisture in compressed air systems can damage tools, corrode pipelines, and compromise product quality—leading to downtime and costly repairs.
A refrigerated compressed air dryer removes water vapor by cooling the air to near-freezing temperatures, causing condensation that is then drained. The result is clean, dry air that protects your equipment, prevents rust, and ensures operational efficiency.
What Is a Refrigerated Compressed Air Dryer?
A refrigerated compressed air dryer reduces the moisture content of compressed air using a refrigeration-based cooling system.
As air passes through the dryer:
It is cooled to 35°F–50°F (1.6°C–10°C)
Water vapor condenses and is drained
Dry air is reheated slightly before returning to the system
Types of Refrigerated Air Dryers:
Non-Cycling Models: Run continuously; simple, reliable, and cost-effective for steady loads.
Cycling Models: Adjust cooling based on demand, saving energy during low usage periods.
How It Works
Hot, moist compressed air enters the dryer.
Air is cooled in a refrigeration heat exchanger.
Condensed water is collected and removed.
Dry, slightly reheated air exits for use in tools and machinery.
This process delivers consistent dew points and moisture-free air.
Key Features and Benefits

Frequently Asked Questions
Q1: How does it work?
It cools air to 35°F–50°F, condensing moisture for removal, delivering dry air to your system.
Q2: Difference between cycling and non-cycling dryers?
Cycling dryers adjust cooling based on demand to save energy; non-cycling dryers run continuously.
Q3: Typical dew point?
+3°C (37°F), suitable for most industrial applications.
Q4: Can it be installed outdoors?
Standard models are indoor rated; weatherproof versions are available.
Q5: Is pre-filtration necessary?
Yes. Pre-filters remove oil and particles, extending dryer life.
