Johnson Controls has expanded its line of Quantech QTC3 Air-Cooled Scroll Chillers with two models that offer a smaller footprint and increased efficiency. With the introduction of Quantech™ models 40T and 50T, the new product range is expanded from 40 to 230 tons. These models are also part of the stock program available for quick shipment. The 40T and 50T models are outfitted with brazed plate evaporators and microchannel condensers allowing for more efficient heat transfer to help reduce total cost of ownership. The QTC3 scroll compressors include two independent circuits for partial redundancy.
The environmental design of the QTC3 includes zero-ODP HFC-410A refrigerant and up to 50 percent less refrigerant charge. Units include full-load and part-load efficiencies that meet or exceed ASHRAE standards. The unit also contains native building automation system (BAS) communications, including BACnet®, Modbus and N2. Made-to-order options including variable speed drive condenser fans (to further enhance part-load efficiency and sound) and integral pump packages that offer a single purchase, shipment and install solution are also available with these new units.
