The flat shape of the Mighty-Blade provides greater surface area inch for inch of length than traditional, round elements. With the Mighty-Blade, equipment can be designed with more wattage in less linear space than with conventional elements. Or, by replacing an existing tubular heater with a Mighty-Blade of the same length, the watt density is significantly reduced. In immersion applications, the narrow profile increases the natural convective flow of materials being processed, resulting in lower sheath temperatures and improved heat transfer to the process.
Materials being processed are less susceptible to degradation.
In processes where these considerations are not as critical, watt densities can be reasonably increased. The design consists of two or three precisely positioned nickel chromium resistance wire helixes, Magnesium Oxide insulating material, and an incoloy or stainless steel sheath. These components are then compacted to maximum density for excellent heat transfer from the coils to the sheath and dielectric strength. The multiple coil design permits an individual element the flexibility to be wired at the installation in single phase, three phase, three heat or dual voltage. 2.3 square inches per linear inch on the Mighty-Blade versus 1.49 square inches per linear length on the tubular allows more wattage or lower watt densities.
