FORM QTC2-eg1 (515)IntroductionQuantech is proud to present the Model QTC2 Air-Cooled Scroll Chiller.The QTC2 Air-Cooled Scroll Chillers provide chilled water for all air conditioning applications using central station air handling or terminal units. They are completely self-contained and are designed for outdoor (roof or ground level) installation. Each unit includeshermetic scroll compressors, a liquid cooler, air-cooled condenser, a charge of refrigerantR-410A, and a weather resistant microprocessor control center, all mounted on a rugged,formed-steel base.GENERALThe 15 - 46 Ton (53 - 162 kW) QTC2 models are shipped complete from the factory readyfor installation and use.The unit is pressure-tested, evacuated, and fully charged with Refrigerant-410A and includes an initial oil charge. After assembly, a complete operational test is performed withwater flowing through the cooler to assure that the refrigeration circuit operates correctly.The unit structure is heavy-gauge, galvanized steel. The steel is coated with baked-onpowder paint, which, when subjected to ASTM B117 1000 hour, salt spray testing, yieldsa minimum ASTM 1654 rating of “6”. Corrosion resistant wire mesh panels are added toprotect the condenser coil from incidental damage and restrict unauthorized access tointernal components. Unit also includes service isolation valves as standard. Units aredesigned in accordance with NFPA 70 (National Electric Code), ASHRAE/ANSI 15 Safetycode for mechanical refrigeration, ASME, listed and labeled with Intertek Testing Services(ETL) and rated in accordance with the latest version of AHRI Standard 550/590.COMPRESSORSThe chiller has suction-gas cooled, hermetic, scroll compressors. The compressors incorporate a scroll design that is compliant in both the axial and radial direction. All rotatingparts are statically and dynamically balanced. A large internal volume and oil reservoirprovides greater liquid tolerance. Compressor crankcase heaters are also included forextra protection against liquid migration.COOLERBrazed plate heat exchangers are UL (Underwriters Laboratories) listed. Installing contractor must include accommodations in the chilled water piping to allow proper drainageand venting of the heat exchanger. Water inlet and outlet connections are grooved forcompatibility with factory supplied ANSI/AWWA C-606 connections.The cooler is equipped with a heater controlled by a separate thermostat. The heaterprovides freeze protection for the cooler down to -20 F (-29 C) ambient. The cooler iscovered with 3/4” (19mm) flexible, closed-cell, foam insulation (K 0.25).QUANTECH5
FORM QTC2-eg1 (515)Introduction (Cont'd)A 40 mesh strainer (0.5 and 1.5 mm) is recommended upstream of the heat exchanger toprevent clogging.CONDENSERCoils – Fin and tube condenser coils of seamless, internally-enhanced, high-condensingcoefficient, corrosion resistant copper tubes are arranged in staggered rows, mechanically expanded into aluminum fins. Integral subcooling is included. The design workingpressure of the coil is 650 PSIG (45 barg).Low Sound Fans – The condenser fans are composed of corrosion resistant aluminumhub and composite blades molded into a low noise airfoil section. They are designed formaximum efficiency and are statically and dynamically balanced for vibration-free operation. They are directly driven, and positioned for vertical air discharge. The fan guards areconstructed of heavy-gauge, rust-resistant, PVC (polyvinyl chloride)-coated steel wire.Motors – The fan motors are Totally Enclosed Air-Over, squirrel-cage type, current protected. They feature ball bearings that are double-sealed and permanently lubricated.6QUANTECH

FORM QTC2-eg1 (515)Accessories and OptionsAll options are factory installed unless otherwise noted.ELECTRICAL OPTIONSSingle-Point Non-Fused Disconnect Switch – Unit-mounted disconnect switch with external, lockable handle (in compliance with Article 440-14 of N.E.C.), can be supplied toisolate the unit power voltage for servicing. Separate external fusing must be supplied,by others in the power wiring, which must comply with the National Electrical Code and/or local codes.Single-Point Circuit Breaker – A unit mounted circuit breaker with external, lockablehandle (in compliance with N.E.C. Article 440-14), can be supplied to isolate the powerfor servicing. (This option includes the Single-Point Power connection.)Control Transformer – Converts unit power voltage to 115-1-60 or 115-1-50 if 50Hz isselected (0.5 or 1.0 KVA capacity). Factory mounting includes primary and secondary wiring between the transformer and the control panel.CONTROL OPTIONSAmbient Kit (Low) – Standard units will operate to 25 F (-4 C). This accessory includesall necessary components to permit chiller operation to 0 F (-18 C). (This option includesthe Discharge Pressure Transducer/Readout Capability option.) For proper head pressure control in applications below 25 F (-4 C), where wind gusts may exceed five mph, itis recommended that Optional Condenser Louvered Enclosure Panels also be included.Ambient Kit (High) – Required if units are to operate when the ambient temperature isabove 110 F (43 C).

FORM QTC2-eg1 (515)Accessories and Options (Cont'd)Service Isolation Valve – Service isolation valves are standard to unit. This includes asystem high pressure relief valve or internal compressor relief mechanism in compliancewith ASHRAE 15.Hot Gas By-Pass – Permits continuous, stable operation at capacities below the minimum step of compressor unloading to as low as 5% capacity (depending on both the unitand operating conditions) by introducing an artificial load on the cooler. Hot gas by-passis installed on only refrigerant system #1 on two-circuit units.Flanges (ANSI/AWWA C-606 coupling) – Consists of two (2) flange adapters for groovedend pipe (standard 150 psi [10.5 barg] cooler).Flow Switch – The flow switch or its equivalent must be furnished with each unit. 150 PSIG (10.5 barg) DWP – For standard units. a vaporproof SPDT, NEMA 4Xswitch (150 PSIG [10.5 barg] DWP), -20 F to 250 F (-29 C to 121 C), with 1” NPTconnection for upright mounting in horizontal pipe will be installed.

For additional application recommendations, contact your localQuantech office.Pre-Coated Fin Condenser Coils – The unit's coils are constructed with epoxy coatedaluminum fins. This can provide corrosion resistance comparable to copper-fin coils intypical seashore locations. Either these or the post-coated coils (below), are recommended for units being installed at the seashore or where salt spray may hit the unit.Post-Coated Dipped Condenser Coils – The unit's coils are constructed with dippedcured condenser coils. This is the choice for corrosive applications (with the exception ofstrong alkalies, oxidizers and wet bromine, chlorine and fluorine in concentrations greaterthan 100 ppm).Enclosure Panels (Unit) – Tamperproof enclosure panels prevent unauthorized accessto units. Enclosure panels can provide an aesthetically pleasing alternative to expensivefencing.Louvered Panels (Full Unit) – Louvered panels surround the front, back, and sides of theunit. They prevent unauthorized access and visually screen unit components. Unrestrictedair flow is permitted through generously sized louvered openings. This option is applicablefor any outdoor design ambient temperature up to 115 F (46 C). Recommended for usewith the Low Ambient kit where wind gusts may exceed five mph (eight kph).Ultra Quiet Fans – The chiller is equipped with specially designed fans and motors to provide lower sound levels yet retain appropriate airflow. The result is reduced fan generatedsound with minimal effect on the chiller capacity or efficiency at standard AHRI conditions.The fans are three-bladed for 60Hz and five-bladed for 50Hz.Vibration Isolators – Level adjusting, spring type 1” (25.4mm) or 2" deflection or neoprene pad isolators for mounting under unit base rails.
