Quincy refrigerated dryers play the important role of removing condensation from compressor systems. Without a dryer, moisture can accumulate in a compressor. With this moisture comes dirt and other particulate matter, which can cause oxidation and other types of premature wear on delicate compressor components. A refrigerated dryer eliminates the problem by cooling moisture in the air to approximately 37°F, where it condenses and can be removed from the compressor system by way of an automatic drain.
Quincy manufactures four main refrigerated dryer product lines: the QPNC non-cycling dryer, the QED cycling dryer, the QPVS variable speed dryer, and the QRHT compact high temperature dryer. The QPNC uses a two-stage heat exchanger configuration to deliver consistent performance when handling smaller, constant loads. Key features of the QPNC include an easy-to-use control panel that allows you to adjust the system for maximum efficiency with zero loss drains. Depending on their configuration, QPNC refrigerated dryers can provide a maximum 230 psig pressure at volumes between 10-3000 CFM.
QED cycling dryers reduce energy usage by cycling the cooling system on and off as demand decreases. They feature a three-stage configuration with a heat exchanger that allows the refrigeration system. Our cycling dryers do not require cooling in a glycol bath and are designed to automatically adjust as the operating environment changes.
QPVS premium variable speed dryers are the most energy efficient dryers in the market. These dryers speed up or slow down based off incoming air demand. This allows for a constantly stable dew point even in harsh environments. Also, because of their smart compact design, the QPVS dryers have a smaller physical footprint, and lower CO2 emissions than thermal mass and non-cycling dryers.
Finally, our QRHT product line features a space-saving design that combines an air-cooled aftercooler, refrigerated dryer, moisture separator, zero-loss drain and coalescing filter in one device. A total system solution for your air cooling needs, the QRHT delivers up to 232 psig at between 25 and 125 CFM.
Desiccant dryers differ from refrigerated dryers in that, rather than cooling air to remove moisture, they rely on a desiccant to adsorb potential contaminants. Quincy manufactures four main product lines of desiccant dryer. Our heatless dryers (QHD series) are affordable to purchase and operate, and they feature microprocessor controls and 15% purge rates.
For heavier-duty applications, upgrade to our heated (QHP) series of products. These dryers require less air to regenerate the desiccant and are available with the optional Quincy MicroBurst Regeneration (MBR) system. When set up properly, a QHP desiccant dryer equipped with MBR technology can cut purge requirements in half, saving you money and helping you realize a return on your investment in as little as five months.Other available products include the QBP blow purge desiccant dryer, which is our most efficient dryer, with purge rates down to 1.75%. QBP dryers are also NEMA-4 compliant and feature some of our lowest operating and maintenance costs. We also offer the QMOD and QMD. These include a modular heatless system for light-duty use.
