2.) Ceramic Band Heaters

Advantages:● Lower Operating Cost - Because of superior
insulation,less heat escapes to the air and less
wattage is required to maintain barrel
temperature. Also the heater is safer
because the external surface is much cooler.
Operator Comfort - With the majority of the
heat going directly to your process,the
ceramic band heater gives off significantly
less heat to ambient air thana mica band
heater.
● Longer Heater Life - because all materials
used are rated to operate at very high
temperatures.
● Higher Operating Temperatures
● Flexible - easy to install and remove
● Dual Heat Transfer - Heat is transferred
through both radiation and conduction so a
near perfect fit is not required as with other
heaters, such as mica heaters.
