MIGHTY BLADE PROCESS
HEATERS
 The flat shape of the Mighty-Blade provides greater surface area inch for inch of length
than round elements. With the Mighty-Blade, equipment can he
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
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 .275" x
1" dimension creates anti-corrosion, self-cleaning effects
that significantly extend the Mighty-Blade's useful life by not
allowing the collection of foreign materials on the sheath. 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. The Mighty-Blade can be used in virtually
any immersion, clamp-on, forced air or radiant heating application.

 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. |
