Finned Tubular Heaters

Listing ID #3868532

Finned tubular heating elements are of the type where the surface area is enlarged by a strip in order to heat gases. At high power the surface temperature is small and the heating element is short.
MATRUSREE’s Finned Tubular Heaters are manufactured with the same rugged construction as the standard Tubular Heaters except a MILD STEEL ELECTROPLATED or a corrugated 304 STAINLESS STEEL FIN is helically wound on Heater Tube diameter (304 stainless steel) element. To insure a permanent bond, each end of the fin is fully brazed to the Heater sheath, for optimum heat dissipation and efficiency, as Brazed fins transfer heat at about double the efficiency of unbrazed designs. These heaters are ideal for heating air and select gases in forced and natural convection applications.
