About Heating Elements

Compare insertion heaters for metal parts vs. immersion heaters for liquids. Then choose the right wattage for your application.

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.

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.
