Large selection of lengths, wattage and watt densities. UL Component Recognized Finned elements (exclusive construction). High-quality, coiled nickel-chrome resistor wire is uniformly spaced over the width and length of the finned strip element, then embedded in high-grade refractory material which both insulates the wire and transfers heat rapidly. The refractory is then compressed to rock hardness and maximum density under tremendous hydraulic pressure to improve heat transfer from coil to sheath. Elements are oven baked at high temperatures to semi-vitrify and mature the refractory. Sheath material is either rust-resisting iron or chrome steel. Fins of aluminized steel are provided to improve that transfer to the air. Elements are individually replaceable. Rust-Resisting Iron Sheath for Sheath Temperatures to 750°F Max.
