Design allows easy access to all major components. Unique design is fully serviceable and maintainable without removal of module from the chiller bank or disassembly of headers. High-efficiency, variable-speed, EC [electronically commutated] condenser fans and acoustical design provide low operation noise levels. Modular chillers offer true redundancy with separate module electrical feeds and integral water-isolation valves, permitting maintenance of one module while remaining system continues operation. The packaged air cool product offers low operating noise from high-efficiency EC fans and a high-efficiency rating exceeding ASHRAE 90.1 minimum requirement.
