UNPARALLELED PERFORMANCEUNPARALLELED PERFORMANCE

The Quincy QSI® rotary screw compressor combines around-the-clock dependability with one of the most efficient, positive displacement airends available. Oversized rotors, low RPMs, and the Power$ync® advanced controller ensures maximum air production using minimum horsepower, which means bottom-line-productivity.

Backed by an available five-year airend warranty, the Quincy QSI features an exclusive Triplex bearing arrangement, a triple lip shaft seal, and boasts an airend life of more than 130,000hours. This is the standard of True Blue Reliability that perpetuates the value of Quincy.

The Quincy QSI airend is the result of over 30 years of proven performance and machining expertise. Starting with astate-of-the-art rotor profile, each rotor is measured using a polar coordinate measuring machine-with an allotted tolerance of 0.0005 an inch.

Beyond this highly efficient rotor profile and unparalleled precision manufacturing standards, Quincy rotors are oversized-almost 62% larger than most competitors. This means long compressor life and increased efficiency.

An oversized, heavy-duty inlet filter and oversized fluid and aftercoolers are standard on the Quincy QSI. With these and other standard features designed to work in harsh operating � conditions, the Quincy QSI is truly one of the most reliable compressors available.

Rotor diameter, length, and speed deter-mine the acfm that can be produced. Logically, this means that a smaller airend with smaller rotors must turn faster than a larger airend with larger rotors to produce the same acfm.

Airend Efficiency:

Larger rotors turning slower produce more acfm per brake horsepower. Typically, the clearance between rotors is known as the “leakage path.” Smaller rotors have a much greater “leakage path” than larger rotors. In addition, the faster the rotors are turning, the greater the drag coefficient. Combined with gear or belt friction, these smaller airend inefficiencies add up to increased power consumption.

Quincy’s oversized Rotor

Competitor’s Rotor

Quincy’s oversized rotors are 62% larger and ensure more acfm per bhp and reduce power consumption.

The Quincy QSI series comes with a PLC intelligent control system. Using the SIEMENS S7 series industrial PLC, it is a control platform you can trust to provide reliable operation under the harshest of industrial ambient conditions. The PLC intelligent control comes with a LCD display, has a user-friendly interface and is easy to operate.

The PLC intelligent control provides different capacity control mode options for higher efficiency: auto-dual control, continuous run control and network control.

In the auto-dual mode, when the pressure rises above the full load pressure setting, the compressor starts to modulate in response to system demand. If pressure continues to rise above the unload pressure setting, the compressor unloads and a shutdown timer will start. If there is no system demand for a preset waiting period, the compressor will shut down the main drive motor and, on air-cooled units, the fan motor. The compressor goes into a “stand-by” mode to conserve energy and continues to monitor system pressure. As soon as the system pressure drops, the controls will react by restarting the compressor.

In the continuous run mode, the compressor will load, unload and modulate according to system demand, but the compressor does not enter the “stand-by” mode and shut down. This control method prevents excessive restarting and extends the motor life in certain applications.

Network mode can operate up to 6 units of QSI in a single network. Each compressor is working in the standard auto-dual mode and coordinating with one another to satisfy system demand according to load requirements. Each compressor starts/stops, hence entering or leaving the network sequentially according to its preset network ID.

Standard industrial PLC means it is expandable and easy for the QSI to communicate with your plant’s network. The PLC control supports Profibus protocol and is able to communicate with your DCS system via the Profibus-DP communication module, hence integrating the compressor controls into your DCS system for remote monitoring.

GAUGE CONTROL PANELGAUGE CONTROL PANEL

All gauges are 2-1/2”, stainless steel backed and bezeled, with silicon-dampened dashpot movements. They provide the reliability and service life of liquid- filled gauges, without the possibility of liquid leaks. Temperature and pressure gauges have both English and metric scales.

Quincy’s exclusive percent capacity gauge details the

compressor load level. When load levels are low, the Quincy

QSI can be shut down with confidence, unlike competitive

machines that may be left on-line because load levels are

unknown.

The Quincy QSI is both reliable and functional. A selector switch on the control panel allows the user to select auto-dual control or continuous run control. In the auto-dual mode, the compressor will load, unload, and modulate in response to system demand. If there is no system demand during the pre-set time delay, the compressor will shut down the main drive motor and, on air-cooled units, the fan motor. The compressor then goes into a “stand-by” mode and continues to monitor system pressure. As soon as the system pressure drops, the controls will react by restarting the compressor.

Continuous run operation can be selected if typical plant operation include frequent, brief periods of no air usage. In continuous run, the timer and the compressor does not shut down. This control method prevents excessive restarting and extends the motor life in certain applications.

The standard compressor control panel has a maintenance and shutdown annunciator panel to indicate various service and shutdown conditions. A graphic display showing the compressor schematic has amber lights to indicate the need to service the air filter, fluid filter, and separator element. Red lights indicate shutdown conditions for high air or fluid temperature, and drive or fan motor overload. These indicators are designed to allow easy remote sensing of all service and shutdown conditions.

The control panel also includes:

� Start button

� Red mushroom stop button with twist lock

� Power-on light

� Lamp test button for annunciator panel

� Discharge air pressure gauge

� Percent capacity gauge

� Hour meter

� Compressor discharge temperature gauge

Maximizing the efficiencies of

the Quincy QSI, the patented

Quincy Power$ync® is the

most advanced electronic

controller in the industry.

Designed to monitor changes

in system air pressure as well

as the rates of these changes,

the Quincy Power$ync micro-

processor works constantly-

adjusting to efficiently meet

the air demands of your sys-

term.

When the Quincy Power$ync

senses a slow drop in pressure,

the response rate is recalibrated

to allow a delayed response

before adding capacity. Often,

the slight air demand causing

the pressure drop is quickly

satisfied-allowing the pressure

to rise again without adding

capacity which translates to

higher power costs. In contrast,

if the pressure drop is great, the

Quincy Power$ync will add

more capacity than pressure

alone would indicate

necessary-preventing exces-

sive system pressure drops and

production losses.

As the most efficient design in variable displacement airends

on the market-Providing the ultimate in both part load

efficiency and electronic control-the Quincy Power$ync has

been awarded multiple patents. Together, the innovative

Quincy QSI airend and the Quincy Power$ync dedicated

microprocessor controller are changing the standards of

efficiency. More acfm per horsepower and the ability to

operate at peak efficiency 24 hours a day make this combina-

tion your most reliable bottom-line investment.

Quincy QSI switch

The Quincy Power$ync is designed to not only provide the best

full and part load operation of a single QSI air compressor, but

also a network of up to 16 QSI air compressor. Control of other

Power$ync machines is obtained through simple network

cables. Each machine, regardless of size, is controlled based

on either a pre-set schedule or by changing system demand.

The Quincy Power$ync will operate the most efficient

machinebased on changes in the system, maintaining a

target pressure as tight as+/-1 psi with adequate

storage. No other compressor manufacturer offers this

level of control and sophistication for either a single

or network of rotary screw air com-presser. Finally,

for peace of mind and continuous operation, no matter

what nature throw your way, Quincy Compressor has

included with every Power$ync machine a fully redundant

manual mode. With a simple flip of a switch your QSI air

compressor will operate like a standard electropneumatically

controlled machine, complete with full safety and protective

features. Only Quincy Compressor gives you this level of

protection to ensure you have of compressed air when you need

it.

SAE O-ring FittingsSAE O-ring Fittings

We’ve designed the Quincy QSI with far fewer potential leak points than other compressors in its class. One

such feature is the use of castings in place of discharge piping. Another is the use SAE o-ring fittings on all

fluid pipe joints over1/4” in diameter. These connections are superior to standard pipe fittings, and are used

extensively for trouble-free installation and operation in the hydraulic and fluid power industries.

Quincy’s air/fluid separator design

and engineered fluids combine to

Produce fluid make-up rates of less

than 3 ppm and downstream carry-

over rates of 1 ppm or less.

All normal maintenance items are

conveniently located at one end of

machine for easy serviceability.

Quincy uses a 10-micron absolute

fluid filter with a special micro-

fiberglass media to provide the

best protection for the airend and

bearings.

The QSI line of compressors uses

oversized aftercoolers with a 8

degree approach at standard condi-

tions. This means more moisture is

removed by the aftercooler,

improving dryer efficiency.
