Finned Strip Heaters for Duct, Ovens, and Dryers
With Split Screw Terminals
With Inline Screw Terminals
With Offset Screw Terminals
These heaters 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 heaters 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.

Moisture-Resistant Bolt- and Clamp-Mount Heaters for Plates, Molds, and Dies
To prevent moisture damage, these heaters 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 (sold separately) to regulate heat output.
All heaters can be attached to surfaces with metal clamps (not included). Space the clamps 3 to 5 inches apart to avoid air gaps that can cause hot spots and lead to premature failure.
Heaters with screw terminals can also be bolted to surfaces with mounting studs and nuts (sold separately).
Surface-mounting connectors (sold separately) are for connecting multiple screw-terminal style heaters.
