CompAir DH Series


When air is compressed the concentration of moisture and other contaminants increases. If allowed to remain in the system this corrosive mixture has a detrimental effect on pneumatic equipment, causing unnecessary production downtime, product spoilage and reduced equipment life.
Compressed air dryers remove water vapor before air reaches the point of use.

Refrigerant Dryers

Refrigerant drying cools the compressed air, whereby a large amount of the water condenses and can be separated. The compressed air is then heated so that condensation does not form on the outside of the pipe work system.

The compressed air cooling takes place, via a closed coolant system, where a refrigerant cooling agent is employed. CompAir uses environmentally friendly gasses for this. By cooling the compressed incoming air with the cooled outgoing air in the heat exchanger, the energy of the refrigerant dryer is reduced.

Desiccant Dryers

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.
