FEATURES
Durability is assured by rugged OMEGALUX™ strip heaters with locked-on aluminized steel fins.
Fast heat transfer to air from large finned area.
Large selection of lengths, wattages 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 temperature 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 heat transfer to the air. Elements are individually replaceable.
CAUTION AND WARNING!
Fire and electrical shock may result if products are used improperly or installed or used by non-qualified personnel. See inside back cover for additional warnings.
