The XDF is a factory pre-wired explosion-proof duct heater.
Standard models are available in three duct sizes, with either
a single or double bank of heating modules. XDF heaters are
available as standard units with T3B, T3A, or T2D hazardous area
temperature codes.
2.2 APPLICATION
The XDF is designed specifically for heating industrial spaces
where potentially explosive substances are or may be present.
Typical hazardous location environments include:
• Water and sewage treatment plants
• Oil refineries
• Pulp and paper mills
• Petrochemical plants
• Grain elevators
• Paint storage booths
• Cement plants
2.3 CONSTRUCTION
The XDF explosion-proof duct heater features heavy-walled carbon
steel finned tubular heating elements with electroless nickel plated
finish to provide safe, efficient, low temperature heat transfer.
