Operating principle of the DRYPOINT® AC

The cold-regenerated DRYPOINT AC adsorption dryer guarantees a continuous supply of qualitative high-quality compressed air. Two vessels filled with desiccant (3) are arranged in parallel. The compressed air is routed through the CLEAR POINT upstream filter and the BEKOMAT condensate drain off (1), which remove particles and condensate from the compressed air as well as the lower switching valve (2) and into the adsorption vessel (3). It is then dried there to the required degree of dryness (pressure dew point). It subsequently flows through the upper switching valve (4) and a CLEARPOINT downstream filter (5), in which any possible resulting abrasion from the desiccant is retained. The dried and purified air is now available for use. While the compressed air is dried in one vessel, the regeneration of the adsorption agent takes place in the other. For this purpose, a partial flow of already dried air is relieved via a nozzle (6) to atmosphere pressure and routed through the desiccant bed for regeneration before it is subsequently released through a silencer (7) into the atmosphere. The switch over between both containers is executed as time-dependent in a specified cycle, optionally also as dew point-dependent. The dew point measured value can, of course, be transferred on optionally to a data logger such as the METPOINT BDL.
