Freezing Air Dryer

In the compressed air purified system, refrigerated compressed air dryer is the preferred equipment to remove water.

Only dry compressed air is also clean compressed air, the moisture in the compressed air network conjoins dirt particles

You will probably also need a drain somewhere to get rid of the water (can be liters of water per day!).

If for some reason the dryer dries the air to below 0 degrees Celsius, the water will freeze and the ice will block the pipes.

The maximum air flow that can flow through your dryer must be higher than what your compressor can deliver.

The non-cycling is the most common type and is extremely reliable and have the lowest maintenance costs.

There are basically two types of refrigerated compressed air dryers. Cycling and non-cycling.

The evaporator is located at the top of the dryer the whole area at the top is the insulated evaporator.

while the refrigerant gets warmer. The refrigerant is compressed by a small compressor and cooled again in the condenser.

In a separate circuit, liquid refrigerant is evaporated in the evaporator, to cool down the warm compressed air.

The cooling is done in the same way as your freezer and fridge are cooled.

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 liquid water is then removed from the compressed air by a water-trap.

As the name implies, a refrigerated air dryer works by cooling down the air (like a refrigerator).
