Quincy QMOD Heatless Modular Desiccant Dryer
Description
These compact dryers use a small portion of dried compressed air to regenerate the offline tower.
The Quincy QMOD is one of our most advanced desiccant dryer systems. Like the QHD series of products, these compact dryers use a portion of dried compressed air to regenerate the offline tower. Their small footprint has been designed to save floor space without compromising performance or efficiency, making them ideal for use in a crowded lab or tight compressor room.
Use the QMOD dryer to remove moisture, aerosols and mist from a stream of compressed air. A 0.01 PPM polishing pre-filter removes large impurities, while the unit’s specially designed purification cartridges contain a high-performance desiccant and after-filter that completely removes remaining water vapors.
15 available models accept input from NPT pipe sizes between ⅜” and 1½”, at flow rates from eight to 365 SCFM. A sophisticated electronic diagnostic and control center puts cycle information and other useful tools right at your fingertips, keeping operation and maintenance safe and simple.
Install the QMOD air desiccant dryer horizontally or vertically for maximum flexibility. A true modular system, the QMOD can be counted on to deliver instrument-quality compressed air in practically any situation.

Operating Principles
Desiccant air dryer systems consist of a pair of towers containing silica gel or another desiccant. Quincy machines use our proprietary Q-Sorb product, an enhanced formula derived from activated alumina that provides improved absorption, lower pressure drop and higher crush strength.
As air passes through the towers, water vapor clings to the desiccant, effectively stripping it from the air until a desired moisture content is met. We measure moisture in pressure dew point (PDP). PDP refers to the temperature it would be necessary to cool air to achieve the same amount of dryness. For example, in many process industry applications, a PDP of at least -40°F is recommended. In other words, air is required to have the same moisture level it would have at -40°F.
Desiccant air dryers work in conjunction with an industrial air compressor. Their dual tower design allows you to time drying operations to a standard NEMA cycle, in which the one tower regenerates (purges) while the other performs the drying function. This prolongs desiccant life and allows for continuous operation for extended periods.
The Importance of Efficiency
A desiccant air dryer system is an important component of any industrial operation in which compressed air of a uniform quality is required. Most air dryers run off electrical power. Because they are for continuous use, however, they can represent a significant operating expense over time.
