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.

Bolt- and Clamp-Mount Heaters for Plates, Molds, and Dies

Also known as strip and disc heaters, these 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.

Strip heaters should be bolted onto flat surfaces or attached with metal clamps (not included). Space clamps 3 to 5 inches apart to avoid air gaps that can cause hot spots and lead to premature failure. Heaters with a 430 stainless steel sheath have good corrosion resistance.

Finned Strip Heaters

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 for corrosion and moisture resistance. All heaters require a temperature switch or controller (sold separately) to regulate heat output.

Heaters for Electrical and Mechanical Enclosures

Protect equipment in enclosures from freezing, humidity, and condensation buildup that can cause damage and lead to premature failure. A thermostat automatically turns the heater on when the temperature drops below the set temperature and off when it rises above the set temperature.

Heavy Duty Heaters for Electrical and Mechanical Enclosures

Without Temperature Control

With Adjustable Thermostat

A perforated steel mounting cover shields the 304 stainless steel heating element from damage. These heaters are often installed in enclosures to protect equipment from freezing, humidity, and condensation buildup that can cause damage and lead to premature failure.

Heaters with an adjustable thermostat automatically turn on when the temperature drops below your set temperature and off when it rises above your set temperature. Adjust the set temperature with the dial.

Heaters without temperature control require a temperature switch or controller (sold separately) to regulate heat output.
