Finned Tubular Heating Elements for Duct, Ovens, and Dryers


M-Shape	Straight	U-Shape

These tubular heating elements minimize the risk of sparks and fire from combustible particles in the flow stream, making them a safer choice than open coil heating elements. Finned for increased surface area, they quickly dissipate heat in air and inert gas heating systems such as duct heating elements and convection ovens. Their sheath, fins, and fittings are made of stainless steel, which resists heat and corrosion better than steel. These heating elements require a temperature switch or control (sold separately) to regulate output.

Welded on One End—Heating elements with end fittings welded on one end have one fitting permanently welded for a secure connection, while the other fitting is loose to create room for tube expansion during heating. The extra space helps prevent damage.

Finned Strip Heating Elements for Duct, Ovens, and Dryers

These heating elements have a large surface area to quickly dissipate heat in air and inert gas heating systems used in ducts, ovens, and dryers. They have a 304 stainless steel heating element that resists corrosion and moisture. All heating elements require a temperature switch or controller (sold separately) to regulate heat output.

Moisture-Resistant Bolt- and Clamp-Mount Heating Elements for Plates, Molds, and Dies

To prevent moisture damage, these heating elements have a seamless 304 stainless steel sheath. They bolt or clamp onto flat metal parts to heat the surface through direct contact. All require a temperature switch or controller (not included) to regulate heat output.

All heating elements can be attached to surfaces with metal clamps, such as C-clamps. Space the clamps 3 to 5 inches apart to avoid air gaps that can cause hot spots and lead to premature failure.

Screw-Terminal Wire Connection—Heating elements with screw terminals can also be bolted to surfaces with mounting studs and nuts.
