3 Types of Compressed Air Dryers PA and Their Characteristics

There are four types of compressed air conditioners in the market. The choice of any of them depends on the application for which it is to be used. It is important to know the technology behind each air compressor so that the business picks one that serves best. Here are different types of Compressed Air Dryers PA that the business can select.

Refrigerated Dryers

Refrigerated dryers dry the air by cooling it to low temperatures and condensing the moisture. They produce dew points of around 2°C (36°F). These dryers cannot achieve dew points that are below the freezing points. Therefore, they leave some moisture in the air and cannot be used for applications that are water sensitive.

Chemical Dryers

Chemical dryers dry the air by passing it through a chamber with chemical beads made of calcium chloride and lithium chloride. These chemicals attract water molecules and absorb the water to the point that they become saturated and have to be discarded. Since the dryer achieves dew points of only15°C 27° F, a coalescing filter is required in the upstream to lower the moisture level in the water before it enters the chemical chamber. Sometimes a removal filter is required in the downstream to prevent any carryover of the chemical particles in the dried air.

Desiccant and Membrane Air Dryers

Desiccant dryers pass compressed air over two beds of desiccant materials to absorb the moisture while membrane air dryers pass the air through permeable micro tubes to dry the air. Both of these air dryers are capable of producing dew points as low as -40°F/°C. One can pick these compressed Air Dryers PA if the production applications require consistent dew points or are water sensitive,

A business should pick the dryer that fits the applications with low deviation from the required dew point. Moreover, they should hire a professional contractor for the installation and maintenance of the compressed air dryers. This way, they ensure that there is consistent dry air for use in the production applications.
