PRODUCT DESCRIPTION

The externally heat regenerated  adsorption dry- ers HRE 0375-13600 work according to the dynamic adsorption principle. Wet compressed air streams through a desiccant bed. While streaming through, moisture is drawn out of the compressed air. Since the adsorption capacity of the desiccant is limited, the ?ow direction has to be changed be- fore the desiccant is completey saturated.  Using two parallel adsorption vessels (adsorbers AD1 + AD2) with alternating function, the permanent sup- ply of dried air for consumers is guaranteed.One  adsorber is always  available for drying the compressed air. The second adsorber is regener- ated at the same time. The activation time respec- tively the regeneration time is always shorter than the loading time of the working adsorber.The re- generation of the saturated desiccant is realized in two steps:

1. Desorption in counter-current ?ow to the   adsorption direction with externally heated blower air
2. Cooling of the heated desiccant with blower air running in circular ?ow (loop)

Typical applications for the adsorption dryers HRE are:

●  Central compressed air puri?cation
Generation of dry, oil-free and particulate-free  compressed air (with option pre- and after?lter)
●  Point-of-use applications
Drying and puri?cation of control and instru- ment and process air
●  Automotive industry
Puri?cation of compressed air for painting applications
