Quincy QED Eco-Dri Cycling Refrigerated Dryer

The Quincy QED Eco-Dri is a cycling refrigerated air dryer for shops whose air demand rises and falls through the day. It chills a thermal mass and shuts the refrigeration compressor off when the load drops, so you pay for drying only when air is moving; a non cycling dryer such as the Quincy QPNC costs less to buy but runs flat out all shift. This listing covers the QED-15 through QED-200, 15 to 200 CFM, which fits compressors from about 3 HP up to 50 HP. Every one of these sizes runs on a 115 V single phase outlet, carries a 3/4 or 1 inch NPT connection, is rated to 232 PSI, and ships with a zero loss electronic drain and the Airlogic2 controller. Larger QED sizes to 2,100 CFM are available by quote.

Sizing

Ratings are at 100 F inlet, 100 PSI and 100 F ambient. Pick the size at or above your compressor's delivered CFM, then move up a size if the inlet will run hot (piston compressors without an aftercooler) or the room is hot. The dryer CFM calculator applies the correction factors. Typical pairings: QED-20 for a 5 HP piston, QED-40 for a 10 HP, QED-65 for a 15 HP screw, QED-100 for 25 HP, QED-200 for 50 HP.

What to pair it with

Quincy recommends its QWS water separator and QCF prefilter ahead of the dryer and a 0.01 micron coalescing element after it where oil free air matters; any good coalescing filter does the same job. Feed the dryer from the receiver, not the compressor head, and route the drain to an oil water separator. See every cycling refrigerated dryer or the Quincy dryer line.

Manufacturer description

Quincy QED Eco-Dri Cycling Refrigerated Dryer (15–2100 CFM)

Engineered for energy-efficient moisture control, Eco-Dri holds compressed air at a steady 30% RH across real-world conditions, well below the corrosion point, without the old glycol bath and its leak points. A smart thermal mass and the Airlogic2 controller tune operation automatically for maximum savings and freeze protection, delivering the performance you demand and the reliability you trust.

Why dry air matters
Dry air protects tools, processes, and finished goods while cutting leaks, maintenance, and downtime. Eco-Dri targets RH (not just temperature), keeping systems cleaner, drier, and more consistent. Zero-loss drains eliminate costly compressed-air blow-off (vs timer drains that can waste $$$ annually).

Key advantages

• Cycling efficiency with automatic adjustments; reverts to non-cycling to avoid freezing.
• Steady RH control (~30% RH), not an over-cooled dew point you don’t need.
• No glycol bath means fewer leak points, compact design, and simpler operation.
• Zero-loss electronic drains standard; energy-efficient by design.
• Flow switch on 650 CFM+ models shuts the dryer off when there’s no flow.
• Warranties: 2-year Full Coverage + 10-year Heat Exchanger (thermal core).

Controller & protection

• Airlogic2 controller monitors sensors and manages the thermal core.
• Readouts/alarms: LAT (lowest air temp), ambient temp, RH, freezing alarm.
• Remote monitoring, CAN comms, voltage-free alarm contacts, auto-restart.

Refrigeration system

• QED-15 to QED-100: R134a.
• QED-125 to QED-2100: R410A with a high-efficiency rolling-piston compressor
  (few moving parts, low noise, low vibration, long life; phase monitor ensures proper rotation).

Specs snapshot (selection basics)

• Capacity range: 15–2100 CFM @ 100°F inlet, 100 psig, 100°F ambient (CAGI ADF-100).
• Max pressure: up to 232 psig (QED-15–200); 203 psig (QED-650–2100).
• Cooling: air-cooled across the range; air or water-cooled options on 650 CFM+.
• Power: 115/1/60 on smaller units; multiple voltages/phases on larger models.
• Connections: from 3/4" NPT to 6" flanged, depending on size.

Sizing notes
Use standard correction factors for pressure, inlet temp, and ambient to pick the right model (e.g., 1050 CFM at 120 psig & 110°F needs ~QED-1250 after corrections). Pair with proper filtration for best practice, QWS moisture separator, QCF prefilter, and CXN 0.001 ppm where required.
