Air Dryers
Refrigerated Air Dryer cools 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. There are three model series available: The "F" series has:
  • capacity from 10 to 100 CFM
  • Pressure dew point as low as 35°F.
  • Entire heat exchanger thermally insulated.
  • Stainless steel heat exchanger.
  • Built-in 40 micron particulate filter.
  • R-134A refrigerant.
  • Compressor thermal overload.
  • Mechanical moisture separator with automatic float type drain @99.97% efficiency.
  • Constant pressure expansion valve.
  • Refrigerant suction pressure gauge.
  • One year warranty.
The "A" series has:
  • capacity from 125 to 300 CFM
The "35xx" series has:
  • capacity from 340 to 2000 CPM
Maximum standard operating pressure ranges from 175 psig to 250 psig based on the model. Voltage ranges are 115 VAC, single phase; 208/230 VAC, single phase; 208/230 VAC, three phase; 460 VAC, three phase; and 575 VAC, three phase. In/out connections start at 3/8" O.D. and range up to 6" flange. There are numerous panel, gauge, electrical, and high pressure package options available. Some models are also available as water-cooled and as energy saving cycling dryers.

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.
