Versa-Mount Bend-and-Stay Heaters for Ducts, Ovens, and Dryers
Form these flexible heaters into any shape to mount them through holes and into brackets, slots, and collars. They are also known as tubular heaters and can be used to heat air, liquids, and gases. All require a temperature switch or controller (sold separately) to regulate heat output.

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

Bend-and-Stay Immersion Heaters with
Through-Wall Fittings for Chemical Solutions
Form these heaters 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 heater failure.
