The Caloritech™ DFF Flanged Air Duct Heater with finned tubular (Calrod® type*) elements is designed for use in comfort heating applications such as make-up air heating, air pre-heating, air handling equipment, fan coils, terminal reheating, multi-zone reheating, heat pump auxiliary systems and return air heating.
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.
