Johnson Controls has expanded its YORK line of YLAA Air-Cooled Scroll Chillers up to 200 tons. The company says the extended capacity of the YLAA offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.
The manufacturer also said that the scroll compressors are proven reliable and the 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. The heat exchanger technology allows refrigerant charge to be reduced by as much as 30%.
