Daikin McQuay Pathfinder air-cooled chillers offer three levels of efficiency - standard, high and premium, allowing building owners to specify an HVAC system that exactly meets operating cost goals. Optional variable frequency drives optimize part-load efficiency. Available in 170- to 550-ton capacities, the chiller operates with R-134a refrigerant, which has no ozone depletion potential and no phase-out schedule. The chiller’s performance contributes to possible LEED points by optimizing system energy efficiency and enhanced refrigerant management.
