The Atacama range replaces the previous Hi-Zorb range and has positively driven valves fitted throughout rather than the less reliable shuttle valves previously utilised.
The Atacama products, which are fitted as standard with both pre and post filtration facilities, provide dry air at a dewpoint of -40°C. Lower dewpoint models down to -70°C can also be supplied. They are suitable for applications in the medical, dental, food processing and packaging industries as well as powder coating, printing, laser technology, plasma cutting, pneumatic control and general manufacturing.
Well proven extruded aluminium technology is utilised for the twin desiccant filled towers comprising each dryer, each tower being sealed with aluminium valve blocks at the top.
Incoming air is being dried as it passes through one desiccant bed while the adjoining dryer chamber is automatically being regenerated using the PSA (Pressure Swing Adsorption) principle.
While operating, a small amount of the dried compressed air is used to regenerate the adjacent saturated desiccant bed. This is achieved by the expansion of the introduced air from line pressure to atmospheric pressure, so removing entrapped moisture within the desiccant and thus regenerating the dryer ready for the next change-over cycle. This change-over is instigated automatically, controlled by a digital controller.
The energy-saving system can be further upgraded where required by the introduction of a dewpoint hydrometer probe to provide automatic full dewpoint control. A dewpoint LED display is incorporated in the top right hand corner of the control panel. This smart controller feature can also be retro-fitted to all makes of dryer as an energy saving feature.
