Features of Externally Heated Purge Desiccant Air Dryer :
Externally heated Purge Desiccant Air Dryer is a new economic
product developed by our company; This series product integrating
advantages of heat-exists purge and heatless purge, externally
heating the purge air, reduce it's consumption.
It efficiently avoid the disadvantages of short switching time and
consuming most of the purge air of the desiccant air dryer, and
wasting electricity of heat-exists air dryer.
This product has got rationally switch time, little purge air
consumption, also being the most economical Desiccant Dryer in this
line and widely used in metallurgy, electrical, electron,
foodstuff, chemical industry, petroleum, medicine, light industry,
cigarette, apparatus, auto industry and so on.
Externally Heated Desiccant Air Dryer is integrated the advantages
of PSA(Pressure Swing Adsorption) & TSA(Temperature Swing
Adsorption).Absorbing during normal temperature and dense water
vapour; purging during relatively high temperature and less density
of water vapour. That’s to say, absorb water of sorbet, purify
during the purging period by superior purge air of thermal
diffusion and high pressure difference.
The Flow Chart of Externally Heated Purge Desiccant
Heatless Purge Desiccant Air Dryer using micro holes in the
desiccant itself, adsorbing the moisture in the air because of
capillary, desorbing it by pressure drop and adsorbing extra-heat.
Currently, the equipment is making up of two towers, controlled by
the Program Controller, the two towers working alternately, one is
for adsorbing, the other is for desorbing, in this way continually
circulating the work.
