Conical or irregular shaped heaters are made
to fit unconventional forms. Heat transfer considerations impose limitations
on the overall design and construction of these heaters. Our engineers
are available to discuss the requirements of each application.
Square and rectangular
Mica band heaters can be made square, rectangular or
multi-sided to suit your specific requirements.
Reverse
Reverse Mica band heaters are used in applications where
heating from inside the barrel is required. The outside shell of these
heaters is the heating surface and all the terminations and clamps are
located on the inside of the Mica band heater.
The cylinder should be clean from any
contaminants and foreign materials.
The heater should be tightened firmly
on the cylinder. The rims should be gently tapped with a plastic mallet
and the heater re-tightened.
Energize the Mica band heater for a short period
of time and then re-tighten the fasteners. To compensate for thermal
expansion, large diameter heaters should have spring loaded fasteners.
One piece construction heaters should
be opened only slightly, and made to slide on a cylinder. Two piece
construction or flexible heaters should be used when a heater has
to be fully opened.
