Short-term power loss from power interruptions, brown-outs or utility switching can quickly turn into a critical loss of cooling in mission-critical processes.

Short-term power loss from power interruptions, brown-outs or utility switching can quickly turn into a critical loss of cooling in mission critical facilities. To help processors cope with such interruptions, McQuay International added a RapidRestore option for its Daikin McQuay Pathfinder Model AWS air-cooled chillers with variable frequency drive (VFD).

The RapidRestore option allows the chiller to restart in as little as 30 seconds after power is restored, making it well suited for cooling-critical manufacturing processes. The restore option helps solve power loss concerns by quickly returning processes to the necessary cooling levels, eliminating downtime.

The air-cooled chiller with VFD reduces electrical utility expenses to levels similar to those from more complex water-cooled systems, says Eddie Rodriguez, chiller product manager at McQuay International, Minneapolis. Rodriguez also notes that the chiller's compressor and fan design allow it to offer low sound levels.
