Tutco SureHeat Hot Air Heater Serpentine VI

Like the Serpentine II heaters, this version offers a similar AND larger triple pass exchanger housing that allows the heater to run more efficiently and provides an added bonus of safety.  The safer design is a result of the incoming air being used to cool the outer shell of the housing.  This occurs as the air travels the outside length of the heater element before entering the internal chamber containing the ceramic insulation and serpentine coil elements.  Serpentine VI air heaters are available with up to 8000 watts of heating power.  These heaters are very popular for preheating and sealing applications, and they are frequently used in the manufacture of condiment packets, frozen food packages, paper cups, and waterproof gear.
