Ceramic
Band Heaters Description |
| Ceramic
band heaters are medium-to-high temperature heaters
that have 1200ºF as a maximum working temperature.
These durable heaters have in-built ceramic fibre
jackets that make them energy efficient. Ceramic
band heaters are available with different terminal
styles, are fully flexible, and can accommodate
holes and cut-outs. |

In
a ceramic band heater, nickel-chrome wire is embedded
in a flexible outer wall made of special, interlocking
ceramic tiles, which are assembled like a brick
wall. A ceramic fiber insulating mat and a stainless
steel jacket cover this assembly. This construction
prevents heat loss and reduces electrical consumption
by 20%.
An energized ceramic band heater will have a temperature
of 350 to 450 degrees F on its outside shell when
the inside temperature is maintained at 1200 degrees
F. To improve the conservation of energy, different
thickness of ceramic fiber insulation mats are available.
Heat is transferred from a ceramic heater to the
surface of an application through conduction and
radiation. This is why a tight grip on the cylinder
is not as critical as in other types of heaters.
Moreover, over tightening should be avoided, since
the pressure on the insulation mat reduces its insulating
efficiency.
Ceramic band heaters are made by using different
combinations of ceramic tiles, which are available
only in specific lengths. Consequently, the width
of a ceramic band heater ban falls within a certain
incremental range.
Ceramic band heaters can be manufactured with different
clamping mechanisms, terminations styles, holes
and cut-outs. |

 |
| Flange
lock-up The most economical clamping style, with
#10-32 nuts and screws. |
|
| |
|
|
| |
 |
| Barrel
nuts Barrel nut fasteners with 1/4-20 socket head
screws are standard on all ceramic band heaters.
This style can accommodate springs which compensate
for thermal expansion. |

|
|
| |
 |
| Latch
& trunion Available on heaters that are 10”
or bigger in diameter. This clamping style provides
ease of installation and removal. |
