Duct Heater
Caloritech™ Air Duct Heaters are designed for use in comfort heating applications such as makeup air heating, air preheating, air handling equipment, fan coils, terminal reheating, multizone reheating, heat pump auxiliary systems and return air heating. Unlike open coil designs, duct heaters fitted with tubular elements are not subject to hazards of electrical shock, which allows installation closer to a register or grille.
DFF Series – Flanged Duct Heater with finned tubular heating elements
DIF Series – Insert Duct Heater with finned tubular heating elements
The finned tubular elements are constructed using a steel tube with corrugated steel fins wrapped around it and brazed together. This design increases the heat transfer surface of the element and resulting in a
lower operating temperature than non-finned tubular designs and a more economical heater.
DFT Series – Flanged Duct Heater with non-finned Incoloy® tubular heating elements
DIT Series – Insert Duct Heater with non-finned Incoloy® tubular heating elements
The non-finned incoloy® element design should be chosen where high humidity or slightly corrosive contaminants may be present in the air stream, as this type of element features higher corrosion-resistance than
the finned element design.
