Refrigerated Air Dryers

 
Refrigerated Air DryerCASTAIR Refrigerated Air Dryers

APPLICATION
Refrigerated air dryers use freon to lower the temperature of compressed air, which condenses humidity into water, eliminating it, and creating a 39 degree F pressure dew point. This guarantees no condensation will be present at the point of expansion at your tools & pneumatic devices. By removing moisture overall maintenance costs are lowered by 15-25%, meaning less downtime and assuring high-quality products.

With the addition of a properly sized prefilter, dryer life will be extended and the added cleanliness of the compressed air will ensure much longer life of your tools and pneumatic devises.

Standard Features:

 • All copper/overlapping (T-T design) heat exchanger.
 • 2 year warranty, 10 year warranty on heat exchanger. (When properly installed and maintained with a prefilter.)
 • Steel cabinet with durable powder coated gloss finish.
 • Refrigerant analyzer gauge.
 • ON/OFF switch
 • Power ON light.
 • Programmable electronic time drain for exact drainage requirements. (UA10-A has a float drain)
 • Uses R134A (1 phase)  R22 (3 phase).
 • Max. working pressure 230-psig
 • Made in the USA.
 • USA & Canadian U. L. approved.
 • 8 foot power cord on 115 volt units.
 • Available voltages; 115/1/60, 230/1/60, 230/3/60, 460/3/60, 575/3/60.
 
 • Rated capacities are based on 100 deg. F inlet air, 100 deg. F ambient air and 100 psi.

* Rated capacities are based on 100 deg. F inlet air and 100 deg. F ambient air @ 100 psi.
   For inlet air temperature of 150 deg. F the capacity will be 55% of above ratings. IE; A 100 CFM dryer capacity is 55 CFM @ 150 deg. F inlet air temperature.
   Larger sizes available.
