Important Information About Refrigerated Air Dryers

A compressed air dryer is a device for removing moisture from compressed air. Compressed air dryers can usually be found in a large number of industrial and commercial operations.

The process of compressed air concentrates atmospheric pollutants, including water vapor. You can also look for the best refrigerated air dryers via

This increases the dew point of compressed air compared to free air in the atmosphere and causes condensation in the ducts as the compressed air cools behind the compressor.

Excess water in compressed air, both liquid, and vapor can cause various operational problems for compressed air users. These include freezing of external air ducts, corrosion of pipes and equipment, malfunctions of pneumatic tools for process control, contamination of processes and products, etc.

Refrigerator dryer

Refrigeration dryers use two heat exchangers, one for air-to-air and one for air-to-cooler. The compressor used in this type of dryer is usually airtight and the gas most commonly used is R-134a. 

The purpose of the two heat exchangers is that the cold exhaust air cools the incoming heat and reduces the required compressor size. At the same time, the increased temperature of the water outlet prevents new condensation.

Several manufacturers offer compressors with built-in refrigeration dryers, but they have received mixed market awareness.

Typically, an incorporation pre-filter is installed just before the refrigeration dryer to remove lubricating oil and other contaminants that may contaminate the dryer heat exchanger.
