POCKET VENTILATION SYSTEM
In the PV system offered by us, ambient air is heated upto a temperature of around 100 to 110°c in steam air heaters
and is then delivered by means of a centrifugal fan, via supply air ducting and blow boxes into the cylinder pockets
through the permeable dryer screens for ventilation of cylinder pockets and also for conditioning of dryer fabrics.
This dry and hot supply air ventilates the cylinder pockets and provides a controlled drying environment by keeping
a low and uniform humidity level in cylinder pockets.
