Cooling control panels

June 2005 Enclosures, Cabling & Connectors

Few companies contend with more heat related problems than do glass manufacturers. Control panels in close proximity to molten glass are particularly susceptible. High ambient temperatures caused constant 'nuisance tripping' of the circuit breakers. The 'quick fix' solution was to open the panel doors, allowing dirt to enter the panels and created a potential safety hazard.

Solution

Exair model 4330 Cabinet Coolers were installed on each control panel. Cold air was directed through the Cold Air Distribution Kit over the circuit breakers. Thermostat control assured that the Exair Cabinet Coolers would activate only when internal temperatures approached critical levels. Panel doors were closed against dirt infiltration and hazard shock. Downtime was eliminated.

The inherent reliability of the Exair Cabinet Cooler was the important advantage in this application, as they have no moving parts. These cabinet coolers are virtually impervious to hostile environments. Glass plants, steel mills, foundries and casting plants are just a few facilities benefiting from this simple, yet effective technology.
