The most efficient method of drying compressed air: Compressed air is cooled to just above freezing point (known as the dew point) which means that water and oil aerosols contained in the air will condense. During this process the aerosols tend to bind up and also discharge the dirt particles. An amply sized heat exchanger ensures reliability even in temporary extreme conditions. Maximum efficiency and operational reliability can therefore be expected.
Desiccant drying works on the principle of absorption of water vapour through a bed of desiccant material in a pair of chambers. Two types are used, heatless regenerative and heat regenerative. The heatless type uses a percentage of the dried air (purge), for re-generation of the desiccant material, while the heat regenerative type uses an electric heat disk, which reduces the amount of purge air needed for regeneration.
