The Ruffneck™ RDIF Commercial Insert 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 a corrugated steel fin wrapped around it and brazed together, which increases the heat transfer surface of the element resulting in a lower operating temperature than the non-finned tubular element designs.

  • Certified for use in ordinary (nonclassified) locations
  • Designed for use in commercial comfort heating applications
  • Finned tubular element increases heat transfer surface area resulting in lower operating temperature
  • Primary and secondary cutouts for overheat protection are standard on all models
