Heatless regenerated adsorption dryer PICO-DRY

PICO-DRY adsorption dryers are intended for separation of water vapour from compressed air thus reducing dew point. Those dryers were specifically designed for piston compressors with relatively small duty load (frequent start and stop). Adsorption takes place under pressure in the lower column. When the compressor stops the adsorption column is depressurised and the dry air from the buffer vessel is slowly expanded and used for regeneration. Dryer is equipped with an aftercooler as well as with filter making sure that liquid water, oil and other large contaminants will not enter adsorption vessel. Springs in the columns make sure that the desiccant beads will not move during operation. Proven robust design enables efficient and reliable operation, fast installation and simple maintenance.
