Spantech Air Dryers

Water (moisture) in vapour form present in the compressed air cannot be removed by the Moisture Separator and Filters. It can be removed by two methods a by cooling the air further to lower temperatures by using cooling media such as refrigerant ( Refrigeration Air dryer) or chilled water/ brine (Compressed Air Chiller Dryer). These Dryers can achieve moderate dryness of upto 600 ppm ( moisture equivalent to ADP of -20A C). For better dryness, a Heatless Air Dryer can be used which can give dryness upto 80 ppm (ADP of -40A C), which is accepted as instrument air quality. These two types of Air Dryers cover virtually all industrial applications. Special Air Dryers can also be designed for achieving moisture content below 80 ppm.

These compressed air dryers from our Compressed Air System is dry and moisture-free and can meet the required ISO-8573-1 standards.
