Johnson Controls has introduced Quantech Air-Cooled Chillers, now available exclusively through an independent sales network. Quantech chillers ship virtually immediately from inventory, making replacement available in as little as two days to minimize downtime and restore comfort quickly. Sources report Quantech chillers offer up to 50% annual energy cost savings compared with the replaced chillers, have a low lifecycle cost, meet or exceed ASHRAE standards, and help earn LEED credit with a low refrigerant charge.

There are three models in the Quantech chiller line: the Quantech QTC2 and QTC3 are 15 to 175 ton air-cooled scroll chillers. The Quantech QTC4 160 to 210 ton air-cooled screw chillers with variable speed drives, are built to order.

  • The QTC2 (15-50 tons) provides chilled water for all air conditioning applications using central station air handling or terminal units. The state-of-the-art installation uses tube and fin condensers, brazed plate evaporators, and scroll compressors.
  • The QTC3 (55-175 tons) offers full load and part load efficiencies that meet or exceed ASHRAE standards and operates at 125 degrees Fahrenheit and down to zero degrees. The scroll compressors are reliable and deliver the proven design of two independent circuits for partial redundancy.
  • The QTC4 (160-210 tons) combines cutting-edge technologies in compressors, heat exchangers, condenser fans and chiller controls to deliver unmatched efficiency. The variable speed drive screw compressors dramatically reduce sound levels.
