Technical Data
   
   

Duct Heaters are used in a variety of air and gas heating applications. These are intended to be installed in exitsting ducting and can be mounted in any direction. The heater is comprised of our high quality Incoloy 800 elements mounted in a 3/8" thick flange using bulkhead fittings. This makes the elements easy to replace in the field. High temperature insulation minimizes heat losses while keeping the electrical wiring cooler. The standard duct heater design (PFI) is rated for an outlet temperature of 750 ºF and a high temperature version (PFIL) rated to 1050°F.
