A Mighty-Blade has over 50% more surface area per inch of length than a .475″ dia. tubular element. 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. The narrow width and greater surface area of the Mighty-Blade increases the velocity of many materials as they flow past the sheath. Heat transfer is improved and the Mighty-Blade’s operating sheath temperature is lower than a tubular element. |
A typical application using a 3 tubular element immersion heater at 22 watts per square inch and a rating of 9kw has an immersed length of 47-1/2″ (A). By utilizing the same spatial limits and installing a Mighty-Blade Immersion Heater, the rating, at the same 22 watts per square inch, can be increased to 13.8kw (B). In the same manner, the original 9kw item at 22 watts per square inch needs only a 31-1/2″ immersion length (C). A Mighty-Blade immersion heater with the same dimensions as the tubular element heater would have a watt density of 13.9 at 9kw. Note the vertical position of the Mighty-Blade elements. As illustrated, much more wattage can be packed in the same area, the same wattage can be provided in less area, or, in the same area at the same rating, processes can be heated at significantly lower watt densities with the Mighty-Blade. |
