Air Dryers

Refrigerated Air Dryer

Refrigerated air dryers cool high temperature air from the compressor down to 35-39°F based on design conditions of 100°F inlet, 100 psig and 100°F ambient. The "35xx" and "40xxW" series have a capacity from 2300 to 15,000 CPM. Maximum standard operating pressure ranges from 175 psig to 200 psig based on the model. Voltage ranges are 208/230 VAC, three phase; 460 VAC, three phase; and 575 VAC, three phase. In/out connections are range from 6" to 12" flange. There are numerous panel, gauge, and electrical options available. Some models are also available with water-cooling.

Air Flow Variance Factors
1) As Inlet Air Temperature increases, Flow Capacity will decrease:
Inlet Air Temperature 90°F 95°F 100°F 110°F 120°F
Flow Capacity Multiplier 1.23 1.13 1.00 0.83 0.69
2) As Air Line Pressure increases, Flow Capacity will increase:
Air Line Pressure 60 psig 80 psig 100 psig 120 psig 150 psig
Flow Capacity Multiplier 0.88 0.95 1.00 1.04 1.08
3) As Ambient Air Temperature increases, Flow Capacity will decrease:
Ambient Air Temperature 80°F 90°F 100°F 110°F
Flow Capacity Multiplier 1.14 1.07 1.00 0.92
4) As Dew Point increases, Flow Capacity will increase.
If design conditions (100°F, 100 psig, 100°F ambient) remain the same, but a higher dew point is acceptable, the Flow Capacity will increase approximately in accordance with the following multipliers:
Dew Point 39°F 45°F 50°F
Flow Capacity Multiplier 1.05 1.15 1.20
These figures are simply general rules, multipliers, and formulas to help you select a dryer.
