In heavy-duty industrial operations, water vapor in compressed air equipment can lead to premature failure, corrosion, frozen air lines, quality control issues and a range of other operational problems. A desiccant air dryer system purifies compressed air by absorbing moisture. You can find these systems in any industrial application in which reliable equipment and exceptional quality control is necessary.
Quincy Compressor manufactures a full line of desiccant air dryer systems. Our products provide air purification from -40°F PDP down to -100°F PDP. These dryers are built and designed to provide the smallest footprint possible while ensuring maximum performance. Quincy desiccant dryers have ASME and CRN designed pressure vessels standard. Also, standard with the desiccant dryers is a 2-year package warranty and a 5-year valve warranty.
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. That’s why it’s important to choose a machine from a manufacturer you can trust.
Quincy Compressors has been in business since 1920. Our products are designed to work together to provide a complete compressed air solution for any heavy-duty or industrial application. Our current line of products includes heatless, heated purge, blower purge and modular desiccants.
