Desiccant Dryers

Quincy desiccant air dryers purify compressed air by absorbing water vapor. The units direct the flow of wet compressed air through a bed of highly adsorbent desiccant.

Only Quincy air dryers have Q-Sorb - the first significant improvement in activated alumina in many years - as the adsorbent desiccant. The uniform size of its beads minimizes channeling and allows more efficient use of the entire dryer tower, thus reducing operating costs. Q-Sorb's higher crush strength and low abrasion characteristic also add to Quincy desiccant air dryer performance as they reduce dusting, which results in longer filter element life, longer desiccant life and lower pressure drop - all moneysaving features.

Heatless

These dryers use a small portion of the dried compressed air to purge the off- line tower: 

Initial cost: Low  -  Operating cost: Moderate to High  -  Maintenance cost: Low

Heated Purge

These dryers use less dried compressed air to purge the off line tower than the heatless series

Initial cost: Moderate  -  Operating cost: Moderately Low  -  Maintenance cost: Low

The optional Quincy MicroBurst Regeneration (MBR) system is the only full-load energy saver available for use with heated purge desiccant air dryers. The MBR cuts purge requirements in half and seriously reduces heater “on” time. When equipped with the Quincy MBR, our Heated Purge dryers use 50% less energy. ROI can be realized within 5 months, depending on dryer size and local power costs.

Blower Purge

These dryers combine heat with forced ambient air for regeneration

Initial cost: High  -  Operating cost: Moderately Low  -  Maintenance cost: Moderately Low
