Quantech™ has expanded its line of QTC3 Air-Cooled Scroll Chillers up to 200 tons. The company says its new QTC3205 offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.

The QTC3 (55-200 tons) offers full- and part-load efficiencies that meet or exceed ASHRAE standards. Made to order options now include variable speed drive (VSD) condenser fans to further enhance part load efficiency and sound, as well as integral pump packages to offer a single purchase, shipment, and install solution. Units are equipped with two independent circuits for partial redundancy. They also feature a brazed plate heat exchanger, microchannel condenser, and native BAS communications, including BACnet®, Modbus, and N2.

In addition to the QTC3, the Quantech line of air-cooled scroll chillers includes the Quantech QTC2 scroll chillers (15-50 tons) as well as the Quantech QTC4 (150-210 tons) variable speed drive screw chillers.
