Refrigerated Air Dryers

 
CASTAIR Refrigerated Compressed Air Dryers

APPLICATION
Refrigerated compressed air dryers use freon to lower the temperature of compressed air. This temperature reduction condenses the water vapor within the compressed air into droplets, allowing it to be eliminated through an onboard condensate drain. CastAir Refrigerated dryers are designed to maintain a 39 degree F dew point, which insures that little condensation will be at the point of expansion at your air tool, paint booth or other pneumatic devise. By removing moisture, overall air system maintenance cost and downtime is lowered by 15-25%, increasing productivity and quality. With the addition of a property sized pre-filter (required for warranty), dryer life will be extended and because of the added cleanliness, air tools and other pneumatic devices will be further extended.

Standard Features:

 • Unique pre-cooling aluminum heat exchanger design.
 • Vertical heat exchanger construction insures no moisture carry over under low air flow conditions.
 • 6.4 foot power cord on 115 volt models
 • 115v/1/60, 208-230V/60 and 460V/3/60 power options
 • Maximum 200 PSI operating pressure
 • Hot gas bypass valve prevents freeze-up regardless of air flow.
 • R134a or R404a environment friendly refrigerant
 • Easily maintain electronic auto drain.
 • Fan control
 • Large moisture holding cavity.
 • Electronic operation control.
 
 

Rated capacities are based on temperatures of 100 deg. F inlet air,
100 deg. F ambient air and 100 psi.  

For other air temperatures of 150 deg F the capacity will be 55% of
the below rating. IE: A 100 CFM dryer capacity is 55 CFM @ 150 deg. F
inlet air temperature.
