Daikin Applied announced upgrades the 100%-configurable Pathfinder air-cooled screw chiller, including a higher efficiency compressor, factory-installed pump packages and ECM condenser fan motor options. Customers can choose to switch from induction motors, the standard option, to electronically commutated motors (ECMs) for free-cooling units, allowing for better part-load efficiency and integrated part-load value (IPLV).
