Kolosal 100- 20,000 cfm (Shell & Tube)
For every 11°C (20°F ) drop in temperature of the compressed air the moisture holding capacity of the air reduces by 50%. Refrigerated air dryers work by using a refrigerant to cool the air to 3°C reducing the moisture holding capacity of the air. Cooling the compressed air causes the moisture to condense. The cooled air along with the moisture is then passed through a moisture separator in order to remove the condensed moisture.
Kolosal refrigerated dryers employs the well established Shell and tube heat exchanging technology. Material of construction includes a mild steel shell and copper tubes. For refrigerated air dryers, the temperature differential between the air and the refrigerant causes absorption of heat energy from the air; hence, reducing the temperature of the compressed air. This causes the moisture to condense.
