Johnson Controls Introduces Quantech Air-Cooled Chillers

April 13, 2015
Quantech chillers are said to offer up to 50 percent annual energy-cost savings, have a low life-cycle cost, meet or exceed ASHRAE standards, and help earn LEED credit.

Johnson Controls’ new Quantech air-cooled chillers are available for virtually immediate shipment, making replacement possible in as little as two days.

Said to offer up to 50 percent annual energy-cost savings compared with replaced chillers, have a low life-cycle cost, meet or exceed ASHRAE standards, and help earn LEED credit with a low refrigerant charge, the Quantech line consists of:

  • QTC2 air-cooled scroll chillers (15 to 50 tons), which provide chilled water for all air-conditioning applications using central-station air-handling or terminal units. Features include tube and fin condensers, brazed-plate evaporators, and scroll compressors.
  • QTC3 air-cooled scroll chillers (55 to 175 tons), which offer full- and part-load efficiencies that meet or exceed ASHRAE standards and operate at 125°F down to 0°F. Features include two independent circuits for partial redundancy.
  • QTC4 air-cooled variable-speed-drive screw chillers (160 to 210 tons), which combine the latest technologies in compressors, heat exchangers, condenser fans, and controls and dramatically reduce sound levels.

Quantech chillers are manufactured in North America and shipped from a logistics center near Dallas. Service contractors and design-build contractors can source chillers from Quantech representatives.
