Purged Air Heating System
Purge Air Systems take ambient air and heat to a desired temperature, typically to 210F/100C to dry air. Typically, these systems will be skid based with a blower and a panel mounted or a junction box for panel remote location. A Purge Air System functions to flush electrical control equipment with clean air before it is turned on, which ensures that the equipment is not damaged or affected by any air contaminants or pollution.
