When Will A Refrigerant Dryer Not Provide Suitable Drying?

In some applications, compressed air lines may be exposed to temperature below freezing levels. In these applications, the pressure dew point must be reduced to below the levels that a refrigerant air dryer can achieve, in order to prevent ice from forming in the compressed air lines. There are many applications where compressed air may come into contact with chemicals, food products or other products in which water vapor in the compressed air may interact negatively in the process. These applications are referred to as “process” applications, and it is often necessary to remove almost all of the water vapor from the compressed air. There are also applications where compressed air is used for instrumentation purposes, and water vapor will negatively affect the instruments.

These are all applications where desiccant air dryers are required. There are international standards for purity of compressed air for particulate and oil content, and dew

When Should A Refrigerant Dryer Be Used?

Refrigerant Dryer

There are several types of compressed air dryers on the market, and many different applications for drying compressed air. Many industrial and commercial applications for compressed air will be for hand tools or the operation of pneumatic cylinders and valves in an indoor applications. These are referred to as “power” applications. For the most part, these applications require the air to be free of condensate (free liquid), which will impede the tool’s performance and cause corrosion, shortening the life of the tool. Refrigerant air dryers are usually selected for these applications. They remove water vapor from the compressed air by means of cooling the incoming air to a level within the design dew point range, separating the condensate, and then draining it off.

Dew Point Requirement in Power Applications

In most refrigerant dryers (usually 15 CFM capacity and larger), the compressed air is re-heated after the separation stage, providing a
