Special graded cast iron deep finned cylinders for quick heat dissipation.
Refrigerated air dryers are the most advanced and cheapest mode of drying compressed air. This dryer operates on the principle that cooling of the compressed air. causes condensation of water carried by the compressed air in vapour form. In the refrigerated type of air dryer the cooling takes place in two stages. The compressed air at about 40 Degree C, which enters the Refrigerated type air dryer, first enters the Precoofer . In the precooler the incoming hot-wet air is cooled by the outgoing cool-dry air. In the bargain the outgoing cool-dry is heated upto operating temperature of about 28 32 degree C.The hot-wet air, now partially cooled. enters the evaporator. In the evaporator, this partially cool air is chilled down to a temperature of about 2 to 8 degree C. Due to this chilling, the moisture carried by air in vapour form is condensed. This chilled air, carrying condensed moisture, then travels into the moisture separator. The moisture separator is a mechanical equipment, in which the condensed moisture is separated from the air by mechanical action. This moisture is drained out from the moisture separator with the help of an automatic drain valve. This dry-cool air is then passes through the precooler as discussed before. By this process you get dry air at the outlet with a pressure dew point temperature of about 4 Degree C or as required. (but above 2 degree C). In case of refrigerated air dryers, the power consumption for air dry- ing is approximately 5.0 kwh for 1000 cubic feet per minute of air.
The theory behind operation of Heatless Dryers, is very simple. Chemicais which have the capacity to adsorb moisture on its surface. These adsorbents are used to dry the air. The adsorber are packed into two columns. The Cornpressed air is passed through this Column of packed adsorbent / dessjcant. It is obvious that after a certain period or drying (i.e. few hours / few minutes) the dessicant looses its capacjty to adsorb more moisture and hence is not capable of drying any more air, in its present Condition.The drying Capacity of the dessicant is restored by the process of regeneration.
This process involves purging out the moisture from the saturated dessicants with the help of the nearly 15% of the air that has already been dried.
All Heatless dryers are provided with 2 (two) towers packed with dessicant (adsorbent). At any given moment, during the operation of the dryers, one tower of dessicant is drying the compressed Air and the other tower of dessicant is being regenerated. The time period for drying and reactivation is equal.
The 3 major types of dessicants used in lndia are Silica Gel, Activated Alumina and Molecular sieves.
