U.L. Recognized - E56973 C.S.A. Certified - 016386-0-000
Features :
-Elements are designed for maximum: Watt density, temperature, heat transfer, and heater life.
-The useful life of a cartridge heating element is determined by how quickly the heat generated in the resistance
wire can be dissipated to the outside sheath. With low and moderate watt density elements, such as Hotwatt's
standard line, the conventional method of inserting helical coils in formed ceramics is an entirely satisfactory
method of construction because the wire temperature relative to sheath temperature even though considerably
higher, is still well within safe long-life operating temperatures.
-The Superwatt cartridge heater accelerates the transfer of heat from the resistance wire to the sheath. This is
accomplished by relocating the wire so that it is closer to the sheath; and swaging the outside diameter of the
heater, thereby compressing the magnesium oxide filler so that it becomes an improved conductor of heat from
the wire while maintaining its dielectric properties. (See diagram below). By improving the heat transfer rate, it
is possible to manufacture elements of higher densities because the differential between the wire temperature
and the sheath temperature has been minimized.
-Long, trouble free service.

The Hotwatt Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mod, platen, or other equipment.
The units are inserted in a milled slot, permitting greater lengths than would be feasible with a drilled or reamed hole. Close dimensional tolerances are held to permit intimate fit for best heat transfer to surrounding medium.
Heating elements arranged just beneath outside surface for maximum heat transfer, minimum wire temperature, and faster heating.
Maximum surface temperatures up to 1200°F. Designations are etched on the sheath to preserve accurate shape.
Long, trouble free service.
Made in U.S.A.
Construction:
-Sealed end.
-Mica.
-Series 300 stainless steel sheath for non-oxidizing, stable service in cavities machined for them.
-Element wire situated in close proximity to outside surface for maximum heat transfer, minimum wire temperature, and faster heating.
-Magnesium oxide packing.
-Ceramic element support.
-Teflon insulated leads: 1/4" square.
Fiberglass insulated leads: 3/8" to 1/2" square, 1/4" x 5/8" and 1/4" x 1" rectangular.

The Revolutionary Watt-Flex®
Split-Sheath Cartridge Heater
* Maximizes Heat Transfer
* Reduces Maintenance Costs
* Reduces the Cost of Process Heating
Watt-Flex Cartridge Heaters run more efficiently, use less power and last up to 5 times longer than conventional cartridge heaters.

Higher Watt Density and Temperatures
Watt Flex heaters produce up to 50% higher warrantable watt-densities than conventional heaters and can operate at much higher temperatures - up to
1900 degF (1030 degC).
The Watt-Flex Cartridge Heater is a high-quality tubular heating element bent back on itself and swaged into a cylindrical format. Dalton manufactures heaters using only high-purity magnesium oxide, nickel chromium resistance wire and stainless steel terminals.
Special filling methods and equipment compact the magnesium oxide inside and around the resistor coil to extreme density. Swaging further compacts the magnesium oxide to virtually maximum density, which yields high dielectric strength and efficient internal heat conduction. Unlike conventional heaters, Watt-Flex cartridge heaters have no ceramic core that can crack during swaging.
The continuous coil and tightly compacted MgO assure highest watt-density and higher operating temperatures.
Watt-Flex Cartridge Heaters run more efficiently, use less power, last longer and are much simpler and faster to replace than conventional cartridge heaters.
