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.

Also known as finned strip heaters, these 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.

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.
