Highlights of Drum Heater Bands

Drum heater bands has a specially designed construction which made for harsh industrial use.
The rust- and corrosion- resistant steel sheath casing gives a perfect combination of high thermal conductivity and physical strength to the heated cylindrical parts.
They can attain a maximum sheath temperature up to 910 F (510 C)
The mica layer is used to insulate the resistance windings.
The thickness of the mica layers is carefully designed to balance dielectric strength and thermal conductivity.
The resistance ribbon wire is wound evenly spaced on a mica core, providing uniform heat distribution and thus eliminating hot spot on the working surface.
Due to the use of mica, the mass of the heater is able to be kept to a minimum.
In order to maximum the heating surface to heated surface contact and improve the heat transfer performance, the external alloy sheath is used for the mica drum heater.
The external alloy sheath, which covering the entire width of the heater, is made of a lower thermal expansion alloy.
The different thermal expansion make the heater grip firmly when heated, which reduce the contact resistance and improve heat migration.
All these could result in a long heater life for drum heater bands.
