Refrigerated Air Dryer

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.

Exal 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.

Features :

Caters to High Ranges (10 cfm and above)

- Manufacturability Range of 100 cfm to 20,000 cfm.
- Largest existing Refrigerated dryer made by Exal has a flow-rate of 15,000 cfm.
- Pressure – 0.5 Barg to 70 Barg

Can be designed for low and high working pressures
- Exal can manufacture Refrigerated dryers with working pressures as low as 0.5 barg.

0-100% capacity control
- All Refrigerated dryers can be designed to work from 0 to 100% load.

Low Pressure Drops
- Exal has made many Refrigerated dryers with 1 psi pressure drop.

Constant pressure dew point 3 °C
- Refrigerated dryers provide a constant pressure dew point +3°C.
- Dew point temperature is measured before moisture separator in the Air line/ circuit.

Maximum Energy savings
- All heat exchangers are designed to correct capacity. This minimizes loss of pressure.
