The QTC2 provides chilled water for all air conditioning applications using central station air handling or terminal units, and it meets or exceeds ASHRAE 90.1-2013 efficiency standards.

• R-410A refrigerant and low charge to help earn a point for LEED E&A Credit 4

• Factory-designed and installed pump package includes pump, strainer, flow switch, circuit balancing valve, expansion tank

• Factory-installed BACnet MS/TP interface. Native communications reduce commissioning time and complexity

• Reliable operation in a variable primary flow system

• Lighter and smaller to minimize installed cost and maximize usable space

KEY TECHNOLOGY ELEMENTS
• Tube and fin condensers, brazed plate evaporators, scroll compressors

The QTC3 offers full load and part load efficiencies that meet or exceed ASHRAE 90.1-2013 and operates at ambient temperatures up to 125°F and down to 0°F.

• 18-40% annual energy cost savings

• Sturdy, corrosion-resistant condenser coils that are easily washable

• Simple replacement of condenser coil if damaged

• Compact, factory-packaged chilled water pumps

• Heat recovery at the chiller

• Green refrigerant and low charge to help earn a point for LEED E&A Credit 4

• Native communication protocols to reduce installation cost and commissioning time

• Heat exchangers – high efficiency brazed plate evaporators, advanced microchannel condensers

• Low-sound fan

• Completely self-contained and designed for outdoor installation

• Includes zero-ozone-depletion refrigerant (R-410A), hermetic scroll compressors, a liquid evaporator, air-cooled condenser and a weather-resistant microprocessor control center, all mounted on a formed steel base.

The QTC4’s combination of state-of-the-art technologies in compressors, heat exchangers (evaporator and condenser), condenser fans and chiller controls enable it to deliver market leading part load efficiency (IPLV or NPLV) while meeting or exceeding ASHRAE 90.1-2013 full load efficiency standards.

• Variable speed drive screw compressors

– Dramatically reduce sound levels at

off-design conditions (up to 16 dBA)

– Reduce energy consumption

• 25-50% annual energy cost savings

• Hybrid falling film type evaporator for optimal

efficiency and refrigerant charge

• Micro-channel type condenser for maximum

heat transfer and minimum refrigerant charge

• Optional condenser fans with variable speed drives for even higher chiller part load efficiency

• Variable primary flow (VPF) system to reduce the chilled liquid flow to match the building demand

• Built to order and delivered in 8-10 weeks
