"CATS" Heatless Air Dryers:
CATS Series Heatless Regenerative air dryer is the most reliable dryer
ever built.Since this unit requires neither heaters nor blowers, it is
inherently more trouble-free than any heat-reactivated dryer.
Comp Air is the manufacturers of complete range of Heatless Compressed
Air Dryer system for moisture removal in air These Compressed air
dryers find use in majority of Industrial compressed air system and
pneumatic applications Following is a brief description of the working
of these compressed air dryers.
A Heatless compressed air dryer is the simplest form of dessicant type air dryer for achieving a dew point of -40oC.
Process: Wet incoming Compressed air after passing through pre filter
passes through the slide piston valve assembly and is directed towards
adsorber chamber where the compressed air passes upward through the
desiccant ( Activated Alumina ). Compressed Air drying takes place by
adsorption. Dry Compressed air from adsorber chamber then passes
through the Check valve assembly and then through the after- filter to
the application or work area.
While Compressed air is being drying in chamber I the dessiccant in
chamber II where the desiccant has been wetted in the previous cycle is
being simultaneously regenerated. The chamber II is depressurized to
atmosphere through the purge valve in the downward direction. A portion
of the dry compressed air passes through the needle valve / orifice
plate through the desiccant and flushes out the desorbed moisture.
When the regeneration is complete, the purge valve is closed and the
tower is slowly repressurised to line pressure for a smooth changeover.
A drying period of 5 minutes provides an efficient dew point of -40oC
or better (at atmospheric pressure). In regeneration process
approximately 30 seconds are required for repressurisation.
