It is the desiccant equipment to fill high alumina gel having mositure and chemical attraction into the
tank in order to supply the pressure air of saturation come from air compressor under high dry status,
A typical regenerative dryer consists of two towers charged with activated alumina desiccant.
One tower dries air, while the desiccant in the other toweed with low pressure and low pressure
and low humidity air.
Often ,heat is added to assist the regeneration process. In this design, a small amount of the dried
air ( from the drying tower ) is expanded to near atmospheric pressure in the regenerating tower.
The dry air becomes super dry on expansion, and readily absorbs the moisture from the saturated
desiccant bed
Like this, the machinery to reiterate the dehumidification and regeneration under allowed time and
then, supply the dried air is called as desiccant air dryer.
Among them, in order to regenerate the desiccant, the dryer to install the electronic heater into
inner tank and dry the absorbent is called as " Internal heater type desiccant air dryer ".
- Heat lossreduced because heat of desorption supplied desiccant bed directly.
- Purge loss also reduced due less heat loss.
- Not installled any motor or blower. Which giving quiet operation and less downtime.
- Installed low density heater for longer life of heater and desiccant.
- Heater to be installed inside of tower, therefore suitable for the mid size models.
