Johnson Controls Inc.: Air-cooled ChillerQuantech Air-cooled Chillers ship quickly from inventory, making a replacement available in as little as two days to minimize downtime and quickly restore comfort. Quantech chillers have a low life cycle cost, meet or exceed ASHRAE standards, and help earn Leadership in Energy and Environmental Design (LEED) credit with a low refrigerant charge. The QTC2 (15-50 ton) provides chilled water for all air conditioning applications using central station air-handling or terminal units. The installation uses tube and fin condensers, brazed plate evaporators, and scroll compressors. The QTC3 (55-175 ton) offers full- and part-load efficiencies that meet or exceed ASHRAE standards and operates at 125°F down to 0°. The scroll compressors deliver the design of two independent circuits for partial redundancy. The QTC4 (160-210 ton) combines technologies in compressors, heat exchangers, condenser fans, and chiller controls. The variable-speed drive screw compressors dramatically reduce sound levels.
