Van Air Freedom Dryers are single tower deliquescent compressed air dryers for stationary applications. Freedom Dryers remove harmful water vapor from compressed air lines.
Wet compressed air enters the bottom of the dryer and flows upward through a bed of deliquescent desiccant, which absorbs moisture as it slowly dissolves. Condensate drops to the bottom of the vessel to be drained. Dry air exits the top of the vessel.
When used with Dry-O-Lite desiccant, the Freedom Dryer automatically provides a dew point that is approximately 20°F lower than temperature of the air at the vessel inlet. For example, if the air inlet temperature is 80°F, the Freedom Dryer delivers a 60°F dew point. If the air inlet temperature is 50°F, the dryer delivers a 32°F dew point.
Ideal for a wide range of applications, Freedom Dryers protect against freeze-ups in the winter and liquid in the summer. Freedom Dryers may be installed inside or outside, and with a pressure drop less than 1% of the operating pressure, they are ideal for low pressure applications. Also with no moving parts or electrical components, Freedom Dryers can be applied with confidence in dirty and hazardous locations.
