Refrigerated Air Dryer
The salient features and benefits:
A compressed air dryer is used for removing water vapor from compressed air.The process of air compression concentrates atmospheric contaminants, including water vapor. This raises the dew point of the compressed air relative to free atmospheric air and leads to condensation within pipes as the compressed air cools downstream of the compressor.
Excessive water in compressed air, in either the liquid or vapor phase, can cause a variety of operational problems for users of compressed air. These include freezing of outdoor air lines, corrosion in piping and equipment, malfunctioning of pneumatic process control instruments and more.
A refrigerated air dryer removes moisture from the air through use of a heat exchanger. An air-to-refrigerant heat exchanger is used to cool the air so that the vapor condenses into water. This water is then collected and drained out of the system leaving only dry air. A refrigerated dryer typically has a dew point around 40°F. In refrigerant dryers chlorine-free,eco friendly refrigerants like R134A & R410A are used.
