Compressed Air Dryer
We provide an ample range of qualitative compressed air dryer
that is manufactured from the premium quality raw materials. We are
well reckoned as one of the dominant heatless compressed air dryer
suppliers, based in India. Utilization of latest technology parts in
the desiccant compressed air dryer ensures durability and efficiency.
Robust structure, safe to use and low maintenance are some of the
salient features of desiccant compressed air dryer that distinguish it
from other brands present in the market.
A Heatless compressed air dryer (drier) is the simplest form of
dessicant type gas or air dryer (drier) for achieving a dew point of
-40°C for compressed air systems and other gas and air dryer (drier)
applications . Process-
Wet incoming Compressed air after passing through prefilter passes
through the slide piston valve assembly and is directed towards chamber
I where the compressed air passes upward through the desiccant.
Compressed Air drying takes place by adsorption. Dry Compressed air
from chamber I then passes through the Check valve assembly and then
through the after-filter to the application or work area.
While Compressed air is 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 depressurised 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 -40°C
or better (at atmospheric pressure ). In regeneration process
approximately 60 seconds are required for repressurisation.
