High density STRIP HEATERS

SSH heaters are strip heaters specifically designed for applications requiring higher operating temperatures and densities. These heaters will operate with a sheath temperature of up to 900° F. The maximum density is 30 watts per sq. in. depending on the application.

SSH strip heaters are manufactured with #304 grade stainless steel, with Nichrome 80 grade resistance wire and ceramic tape.

SSH strip heaters can be manufactured for any voltage, wattage, single phase or dual circuit and various dimensions. Dimensions can vary from 1” to 6” maximum width with a maximum length of 60” (consult us for longer lengths). Multiple styles of electrical connections and terminal housings are offered.
