McQuay International has introduced a RapidRestore option for its Pathfinder Model AWS air-cooled chillers with variable frequency drive (VFD). The option provides peace of mind to facility managers’ who need to maintain necessary cooling levels in mission critical applications. The RapidRestore option allows the chiller to start as fast as 30 s after power is restored, making it suitable for use in data centers, health care buildings, and manufacturing processes. RapidRestore helps solve power loss concerns by quickly returning facilities to the necessary cooling levels, keeping heat-sensitive servers on-line, maintaining patient comfort in critical care areas and eliminating downtime in manufacturing processes.

Chiller unit capacities range from 150 to 530 tons with three new sizes: 150, 175, and 190 tons with VFD. Pathfinder chillers offer three levels of efficiency-Standard, High and Premium-allowing building owners to specify an HVAC system that exactly meets their requirements. The Pathfinder chiller reduces sound pressure levels by 6dBA compared to previous models and features sound pressure levels as low as 65 dBA per AHRI 370 with no attenuation.
