Bend-and-Stay Heating Elements for Ducts, Ovens, and Dryers

Form these flexible heating elements into any shape to mount them through brackets, collars, and holes. They are also known as tubular heating elements and can be used to heat air, liquids, and gases. All require a temperature switch or controller (sold separately) to regulate heat output.

Bend-and-Stay Immersion Heating Elements with Through-Wall Fittings for Chemical Solutions

Form these heating elements into any shape and install them through container walls with the attached bulkhead fittings. They quickly and efficiently heat liquid through direct contact. All require a temperature switch or controller (sold separately) to regulate heat output. The Incoloy heating element has excellent resistance to harsh chemicals.

Note: Fully immerse the heating element in liquid to prevent heating element failure.
