The air dryer is an important component of a compressed air system. It removes moisture through adsorption, absorption, refrigeration, diffusion, or filtration. Dry air is crucial in modern manufacturing processes. If not removed, water can condense in downstream equipment and affect productivity.Compressed air dryers are designed for continuous operation. This helps reduce maintenance and increase production. Air dryers have a range of dew point temperatures that can be used in different applications.
A common type of dryer is the oil-less air dryer. These types of air drying systems require 220 volts to 240 volts voltage. They are also available in a variety of sizes.Desiccant dryers are used in specialty applications, such as waste gases and natural gas. The desiccant in the dryer absorbs the water vapor and re-enters the ambient air. Typically, desiccant dryers are not effective in high ambient temperatures.
Refrigerated air dryers are usually used in industrial applications where the moisture in the air is acceptable. Refrigerated dryers typically operate at a higher dew point than desiccant dryers.Heatless type dryers are the most simple form of a desiccant dryer. They are very effective for compressed air systems. Although they don't generate much heat, they can achieve a dew point of -40 degrees Celsius.
