The Ruffneck™ RDFT Commercial Flanged Duct Heater with non-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 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. 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.
