PARKER MAKE HEATLESS AIR DRYER
The simplest and most common method used to regenerate the adsorbent desiccant material is the ‘heatless’ method (so called as it does not use heat for desiccant regeneration). Using a proportion of the clean, dry process air for regeneration, heatless dryers typically have the lowest capital costs of all adsorption dryer types (due to the simplicity of the heatless design). Being very robust and having fewer components, they typically have the lowest maintenance cost of all the adsorption technologies. Heatless dryers are available to suit all compressed air flow rates from small to large, whereas the more complicated regeneration methods are often only available for higher flow rates due to cost and complexity of the designs.
Heatless Air Dryer
Parker MX dryers provide an outlet dewpoint which inhibits the growth of micro-organisms (allowing their efficient reduction using filtration).
Parker MX dryers use clean, dry purge air for regeneration, eliminating any risk of damage to the adsorption bed or re-contamination of the downstream compressed air.
No heat is used for regeneration; therefore, no insulation is required and loss of dewpoint on column changeover due to inefficient cool down is eliminated.
Parker MX materials of construction are FDA Title 21 CFR compliant & EX1935/2004 exempt

Blower Regeration Absorption Dryers
Blower regeneration dryers do not use process air to regenerate the adsorbent desiccant material, instead they use ambient air for both regeneration and cooling (reducing energy consumption and process air loss).
For regeneration, the ambient air is heated and push across the desiccant bed using a blower.
To cool the desiccant and ensure it is at the optimum temperature for adsorption, the heat source is simply removed, and the desiccant cooled to ambient temperature.
Blower regeneration dryers can be supplied with purge cooling or zero loss cooling utilise existing water sources on site (cooling or chilled water).
