Quantech™ is proud to present the Model QTC3 Air-Cooled Scroll Chiller.
FEATURES AND BENEFITS
Installation
The QTC3 chiller arrives as a factory-assembled package ready to be installed outdoors,
either on the roof or at ground level. The air-cooled condensers eliminate the capital,
installation and maintenance costs of a cooling-tower circuit.
The QTC3 weighs less and has s smaller footprint than other chillers in its class. In fact, it
is 20-35% lighter weight than the market average chiller. When the chiller is roof-mounted
in new construction, the cost of the support structure can be reduced. In building retrofits,
the QTC3 can provide the largest capacity in a given space and existing structure.
Power hook-up could not be any easier with the standard single-point connection. A ter-
minal block, disconnect switch or circuit breaker is provided to meet the unique needs of
every project and minimize installation time and labor. The factory-installed control trans-
former steps down the power voltage to the control voltage.
Chilled-water piping is also simple. The water connections are factory-piped to the out-
side of the unit, for ease of access. Factory-cut grooves, or optional flanges, make pip-
ing connections simple. Optional factory-installed pump kits eliminate the time, cost, and
mechanical-equipment room space necessary to install chilled-water pumps.
Press the start button with confidence – your QTC3 has been run-tested at the factory to
ensure that you will have a successful start-up.
Reliability
The QTC3 chiller is proven and reliable, designed to reduce service calls. The scroll com-
pressors have logged hundreds of thousands of operating hours in numerous different
applications. The corrosive-resistant condenser heat exchangers have been specifically
designed for stationary HVAC applications and have undergone extensive laboratory and
field testing to extend chiller life and improve performance. They are also more rigid than
standard condenser coils, making them less susceptible to damage during rigging, lifting,
and installation of the chiller.
Components are designed to keep the chiller up-and-running. A factory-installed water
strainer prevents debris from affecting unit flow and/or heat transfer. The rugged thermal-
dispersion flow switch is factory-installed at the optimum location in the piping for superior
flow sensing, reducing the potential for nuisance trips. Intelligent controls protect the
chiller while keeping it online, for maximum uptime. Exterior panels of the chiller are
powder-coated with highly durable corrosion-resistant paint.

Efficiency
QTC3 high-efficiency chillers, with their innovative control algorithms, offer industry-lead-
ing energy efficiency. Real-world energy efficiency is measured by IPLV (off-design) per-
formance, and QTC3 chillers provide some of the best IPLVs in their class.
QTC3 also offers an efficiency choice. In addition to the high-efficiency units, QTC3 chill-
ers are available in standard efficiency models with smaller footprints and lower capital
costs.
Only pay for the chiller you need – the multi-efficiency levels of the QTC3 allow you to
decide the best investment for the job.
Flexibility
The QTC3 chiller offers a number of options designed to operate reliably across a wide
range of customer needs. It can cool glycol down to 10°F (-12°C). It can provide heat
recovery up to 140°F (60°C), with up to 85% of total heat rejection captured.
When factory-mounted pump kits are considered, there are now more pump sizes to
choose from. The optional kits come standard with valves, pressure ports, flow switch,
and strainer for quick hook-up, and frost protection to prevent freeze-up. There are also
more pump options available: variable-speed drives, dual pumps, service shut-off valves,
expansion tanks, and additional test ports for temperature and pressure sensing.
Standard low sound and multiple sound attenuation options allow flexibility in locating the
chiller, and reduce the cost for field-constructed barriers.
Sustainability
The QTC3 makes you a leader in sustainability through innovation, not added cost. With
the combination of R-410A refrigerant, which has no ozone-depletion potential, and state-
of-the-art heat exchanger technology that allows refrigerant charge to be reduced by as
much as 30%, the QTC3 chiller provides the most ecologically friendly equipment. Part-
nered with its low-sound properties for noise pollution prevention, this chiller is a true
earth-friendly offering.

Communications
The QTC3 chiller comes standard with native communication capability for BACnet (MS/
TP), Modbus, and N2, with optional capabilities available for LON. The standard unit ca-
pabilities include built-in-scheduling, remote start-stop, remote water temperature reset
and up to two steps of demand (load) limiting depending on model. The standard control
panel can be directly connected to a building automated system via the standard factory-
installed RS232 communication port.
Serviceability
Minimal maintenance is required to keep the unit operating at maximum performance. If
service should ever be required, the QTC3 chiller has been designed to simplify the work,
keeping costs down. The layout of the chiller locates all the major components that can
be serviced near the outside edge. The condenser heat exchangers are light enough that
no crane is required for replacement. And when it’s time to clean them, city tap water,
with water pressure typical of a spray from a common garden hose, is all that’s needed.

Equipment Overview
The 55 - 230 Ton (195 - 800 kW) QTC3 models are shipped complete from the factory
ready for installation and use. The unit is pressure-tested, evacuated, and fully charged
with a zero Ozone Depletion Potential Refrigerant R-410A and includes an initial oil charge.
After assembly, a complete operational test is performed with water flowing through the
evaporator to assure that the refrigeration circuit operates correctly.
The unit structure is heavy-gauge, galvanized steel. This galvanized steel is coated with
baked-on powder paint, which, when subjected to ASTM B117 1000 hour, salt spray test-
ing, yields a minimum ASTM 1654 rating of “6”. Units are designed in accordance with
NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safety code for mechanical refrig-
eration, ASME and rated in accordance with AHRI Standard 550/590.
COMPRESSORS
The chiller has suction-gas cooled, hermetic scroll compressors. The QTC3 compressors
incorporate a compliant scroll design in both the axial and radial direction. All rotating
parts are statically and dynamically balanced. A large internal volume and oil reservoir
provides greater liquid tolerance. Compressor-crankcase heaters are also included for ex-
tra protection against liquid migration. Power wiring is routed through liquid tight conduit.
BRAZED PLATE EVAPORATOR
The compact, high efficiency Brazed Plate Heat Exchanger (BPHE) is constructed with
316L stainless steel corrugated channel plates with a filler material between each plate.
It offers excellent heat transfer performance with a compact size and low weight, reducing
structural steel requirements on the job site.
LD18425

FORM QTC3-EG6 (1118)
QUANTECH 9
The heat exchanger is manufactured in a precisely controlled vacuum-brazing process
that allows the filler material to form a brazed joint at every contact point between the
plates, creating complex channels. The arrangement is similar to older plate and frame
technology, but without gaskets and frame parts.
Water inlet and outlet connections are grooved for compatibility with field supplied ANSI/
AWWA C-606 couplings.
A 20 mesh wye-strainer is provided as standard to provide protection at the evaporator
inlet, particularly at system start-up when construction debris may be present in the piping
system.
The evaporator is equipped with a thermostat-controlled heater. The heater provides
freeze protection for the evaporator down to -20°F (-29°C) ambient. The evaporator is
covered with 3/4” flexible, closed-cell, foam insulation (K=0.25).
A factory-wired flow switch is standard, installed in a pipe section at the outlet of the
evaporator.

CONDENSER
Coils - Condenser coils are made of a single material to avoid galvanic corrosion due
to dissimilar metals. Coils and headers are brazed as one piece. Integral sub cooling is
included. The design working pressure of the coil is 650 PSIG (45 bar). Condenser coil is
easily washable with clear water up to 100 psi (7 bar).
Fans – The condenser fans are composed of corrosion resistant aluminum hub and glass-
fiber-reinforced polypropylene composite blades molded into a low-noise airfoil section.
They are directly driven by independent motors, and positioned for vertical air discharge.
The fan guards are constructed of heavy-gauge, rust-resistant, coated steel. All blades
are statically and dynamically balanced for vibration-free operation.

Motors – The fans are driven by Totally Enclosed Air-Over, squirrel-cage type, current
protected motors. They feature ball bearings that are double-sealed and permanently lu-
bricated.
UNIT CONTROL SYSTEM
The QTC3 chiller is designed with an intelligent control system that operates the chiller
automatically with maximum reliability, safety and ease of use. The controls are factory
tested and with as little user input as a chilled liquid setpoint the chiller will operate to meet
the load demand.
The control system includes native BACnet MS/TP, Modbus and N2 communications, with
LON protocol served through an optional eLink communications card.
The operating program is stored in non-volatile memory (EPROM), so power failures and
battery discharge will not require reprogramming the chiller. Programmed setpoints are
retained in lithium battery-backed RTC memory for 5 years minimum.

Unit alarm contacts are standard. Contacts for remote chilled liquid temperature reset
and two steps of demand load limiting are also standard, for projects without BAS or for
redundancy.
Maximum reliability is achieved through intelligent control. Run hours and starts are av-
eraged across all compressors automatically, and between both pumps of the optional
dual pump hydro-kit. When compressors are cycled off, an anti-recycle timer ensures
the motors have time to cool before starting again, for the maximum service life. At unit
shutdown, the unit pumps down automatically to prevent liquid refrigerant from entering
the compressors at restart, which can cause premature bearing wear and other compres-
sor damage.
Liquid temperature sensors provide feedback to the controller, and logic predicts when
additional capacity will be required based on how quickly the unit has loaded or unloaded
in the past. This prevents unnecessary compressor cycling and helps maintain setpoint
accurately.
If there is a problem that prevents the unit operating properly, the controls are designed to
allow the unit to operate safely while making as much capacity as possible. For example,
if airflow to the condenser coil is diminished due to a dirty coil, the chiller will unload slightly
to provide maximum capacity possible while remaining within the unit operating envelope.
If a fault prevents the unit from starting or causes it to shutdown, the chiller will attempt to
restart three times. If it cannot start, a manual reset is required to alert the operator about
the fault condition. The fault history is stored in the unit controller RTC memory for the
last six fault shutdown conditions. An RS-232 port provides capability to print hard copy
reports (printer available separately).
All controls are contained in a NEMA 3R cabinet with a hinged outer door and includes a
liquid crystal display (LCD) with light emitting diode (LED) backlighting for outdoor view-
ing. There are two display lines, each with twenty text characters per line, and a color
coded 12-button non-tactile keypad with sections for display, entry and printing.
DISPLAY/PRINT provides quick access to frequently needed information:
• Chilled liquid temperatures.
• Ambient temperature.
• System pressures (each circuit).
• Operating hours and starts (each compressor).
• Operating data for the systems.
ENTRY section allows entering setpoints or modifying system values.
SETPOINTS updating can be performed to:
• Chilled liquid temperature setpoint and range.
• Remote reset temperature range.
• Set daily schedule/holiday for start/stop.
• Manual override for servicing.
