Get a low-cost way to remove water from compressed air, by installing a refrigerated compressed air dryer and avoid condensate problems.

A refrigerated compressed air dryer is a type of compressed air dryer, used to dry compressed air. Compressed air always contains water, coming from the air that is sucked in by the compressor.

To protect your piping, tools and equipment, it's best to use a compressed air dryer to dry the air.

Refrigerated compressed air dryers are one of the most common used types of air dryers (for other types, check out our general page on compressed air dryers). They are simple in design, need very little maintenance and are relatively cheap.

A refrigerated compressed air dryer is the standard choice if you're shopping for a dryer and don't have special requirements, like an ultra-low dewpoint. They don't need much or any special maintenance and if you buy a quality one, and install it properly, it's basically set-and-forget.

HOW DOES IT WORK?

As the name implies, a refrigerated air dryer works by cooling down the air (like a refrigerator). The warm wet air enters the dryer, where it is cooled down to about 3 degrees Celsius. All water vapor that was in the air condenses into water. Much like your window does on a cold day. The liquid water is then removed from the compressed air by a water-trap.

After that, the cold air is re-heated to room temperature. Since a lot of water has condensed into water, the air is now much dryer.

The cooling is done in the same way as your freezer and fridge are cooled. In a separate circuit, liquid refrigerant is evaporated in the evaporator, to cool down the warm compressed air. The air is cooled, while the refrigerant gets warmer. The refrigerant is compressed by a small compressor and cooled again in the condenser.
