Compressed Air Dryers

An air dryer is essential for any compressed air system. Water accounts for up to 99% of total liquid contamination found in a compressed air system. Water vapor is water in gaseous form and will pass through water separators and coalescing filters just as easy as the compressed air. Water vapor left in a system can lead to corrosion, equipment malfunction, product quality issues and system failure. Parker offers a comprehensive range of compressed air dryers designed to meet the needs of customers across a variety of industries.
Adsorption dryers are commonly employed to dry compressed air when pressure dewpoint’s below freezing and / or the control of micro-organism growth is required. CDAS / OFAS dryers are heatless adsorption dryers, i.e. the regeneration cycle (purge cycle) uses clean, dry purge air to ensure that moisture is fully removed from the off-line desiccant bed prior to re-pressurization and being brought back on-line. As there is a cost to generate compressed air, the energy consumed by the CDAS / OFAS dryer comes from the regeneration air (purge air) it uses to regenerate the off-line desiccant bed.
