QT5QCB Climate Control 5hp Duplex Reciprocating Air Compressor By Quincy

Quincy QT-5 Climate Control Duplex: two 5 HP two stage pumps on one 120 gallon tank

The Quincy QT5QCB (part number QC05012D) is a duplex climate control package: two Quincy QT-5 two stage cast iron pumps, each with its own 5 HP 460 volt three phase motor, mounted on a single 120 gallon ASME horizontal receiver with a duplex control panel. Each pump is rated 15.5 ACFM at 90 PSIG, so the package delivers roughly 31 ACFM with both pumps running and 15.5 ACFM with one. The panel alternates lead and lag duty between the pumps so wear is shared, and brings the second pump in only when demand outruns the first.

Who buys it

This is the compressor for pneumatic HVAC control air in commercial buildings, hospitals, schools and campuses, and for light industrial plants that cannot tolerate an outage. The duplex layout gives you a built in standby: if one pump is down for service the other keeps the building's controls supplied. Quincy's beveled gap ring design certifies oil carryover at 2 ppm or less, which is why the QT climate control line is specified so often where oil in the control lines would gum up actuators and pilot valves.

Options and what to check before ordering

Choose the package with or without the refrigerated air dryer and with or without an automatic tank drain. Control air almost always needs the dryer; without it, moisture ends up in the pneumatic thermostats and damper actuators. The motors are 460/3/60 only, so confirm you have three phase 460 volt service at the location. Plan for a dedicated branch circuit per motor, sized from the motor nameplate, and leave at least 24 inches of clearance on the pump sides for cooling air and belt service. The pumps run at 622 RPM, which keeps noise and heat low for an indoor mechanical room.

Lead time is 9 to 12 weeks because every QT climate control unit is built to order. If you need a simplex alternative, see the Quincy QT duplex and QT Pro two stage listings, or the Champion duplex R-Series.

Manufacturer description

The Tank Mount Unit is built on a 120 gallon tank and powered by a 5 hp, 460/3/60, ODP, premium efficiency motor with the compressor operating at 622 rpm.

The Quincy QT Climate Control series is designed for maximum productivity and efficiency; it is the reliable choice for climate control and light industrial applications. The QT-5QCB heavy-duty cast-iron construction and quality components make it more than a match for tough working conditions. The aluminum head dissipates heat to ensure the compressor is running as cool as possible while the Quincy valve design provides the highest volumetric efficiency available. Leading the industry with the most CFM per brake horsepower, the Quincy QT-5QCB delivers more air and consumes less energy.

Key Features & Benefits:

• Beveled gap rings ensure a fast break-in and have established Quincy as the climate control leader with a certified maximum oil carry-over of 2 ppm or less.
