Mini Ceramic Ring Heaters: Diameter 38mm, Simple Wiring For Tight
Spaces
1. Brief Introduction
Ceramic band heater is an industrial heating device designed to
wrap around cylindrical objects, such as pipes, barrels, or tubes,
in order to provide controlled and efficient heating. These heaters
are commonly used in various industrial applications where heating
of cylindrical surfaces is required, such as plastic processing,
packaging, extrusion, and molding.
Ceramic band heaters are designed with spirally wound inner
resistance coils evenly threaded through interlocking insulated
ceramic “tiles”. The ceramic core, or “mat” of tiles is housed
beneath a stainless-steel sheet with serrated edges. The notched
edges fold over to secure the ends and a protective inner liner (to
be removed at installation) secures the placement of the tiles.
This combined assembly of the Ceramic Band Heater offers a flexible
heating system that yields efficient transmission of conduction and
radiated heat. The heat of the Ceramic Band originates from the
inner coils that conduct heat at maximum temperatures. The heated
coils evenly deliver heat through the ceramic tiles which radiate
energy to the barrel.
We offer a variety of Ceramic Band styles from standard to custom
configurations. When selecting a ceramic heater, select a heater
that best matches the wattage requirements – to decrease the
frequency of cycling and temperature overshooting, and thereby
increase the life of the heater. When installing a ceramic band
heater to replace a non-insulated heater, decrease the total
operating wattage by approx. 15-30 percent.
2. Features
Built in insulation minimizes unwanted change in temperature along
the barrel
Efficient heat transfer: Heat transfers through radiation,
conduction, and convection, so a perfect fit is not required
compared to other band heaters
Heat transfers are not affected by irregular surfaces or a loose
fit
Because they operate at higher watt densities, they can be used in
wider increments
The number of bands used can be reduced with simplified wiring
The heater is safer with the cooler external surface – over other
band heaters
The flexible design allows easy install and removal
