November 29, 2017, Milwaukee, Wisconsin, United States: Johnson Controls (JCI) has expanded its York line of YLAA air-cooled scroll chillers up to 230 tonnes of refrigeration (TR). According to the company, the extended capacity of the YLAA offers a more cost competitive solution to 23 TR opportunities without sacrificing size, quality and efficiency.

With the smallest footprint in the industry, JCI said, the YLAA (55-230 TR) offers full-load and part-load efficiencies that meet or exceed ASHRAE standards. Available from stock and shipped to locations in the United States within 2-5 days or 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, the company added. The scroll compressors, the company claimed, have proven reliability, and the units are equipped with two independent circuits for partial redundancy. JCI added that the chillers also feature a brazed plate heat exchanger, microchannel condenser and native building automation system (BAS) communications, including BACnet, Modbus and N2.
