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. 15-20 percent.
Ceramic Band Advantages
- 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
Ceramic Band Options
Beads
This Ceramic band style features protective ceramic beads (encasing the lead wires) exiting the ceramic terminal box.
Fiberglass Spring Relief
This Ceramic band heater includes fiberglass leads. The leads are covered and secured to the band by a spring relief component.
Armor Cable
This Ceramic band heater style depicts fiberglass leads covered with a protective armor sleeve. The sleeve assembly is affixed to the band by a copper coupling.
Post Terminals Same End
This Ceramic band heater style can be constructed with the terminals positioned either Vertically or Horizontally. This vertical terminal design is the most common termination. The terminal location is typically 180˚ from the gap. Specify which option you require when you place your order.
Spring Loaded Screw
This Ceramic band heater construction includes spring loaded clamps to allow flexing during thermal expansion of the metals.
T-Box
The Ceramic T-Box band heater design offers excellent protection of the terminals. The knock out holes in the T-box, make allow ease of wiring. There are several lead options available for this T-Box style.
Holes
This Ceramic band heater is designed with the Holes variation, and does not provide insulation. The holes in the outer band allows for more efficiency when used with forced air cooling systems.
Clamping Spring Loaded Screw
This Ceramic band heater is designed with a Built-in Strap Welded Barrel Nuts construction. This design is a common heating solution, and can be paired with all termination variations.
