A helically wound resistance coil made from nickel-chrome wire is precisely strung through specially designed ceramic insulating bricks, forming a flexible heating mat. TEMPCO’s style of Ceramic Insulating Bricks offers several benefits including:
Excellent dielectric strength at high temperatures with high voltages
Ability to interlock and provide a more rigid structure
Allows for heater widths in smaller increments (1/8″)
Reduces the chances of damaging internal coils in transit and handling
Allows for easier installation of the heater onto the pipe
These heaters transmit heat through both conduction & radiation. The element winding is designed to heat the ceramic blocks to the point at which they radiate energy into the barrel as well as conduct energy by being in contact with the barrel – fit is not as critical as in other types of bands.

Reverse Band
Reverse Ceramic Band Heaters are intended for the outer surface of the band to heat the inner surface of a cylinder. These heaters use the same built-in insulation as normal ceramic bands and therefor can either reduce the power needed to heat an application to the desired temperature or offer some thermal protection to anything else that might also be inside the cylinder. Standard Insulation (S): 1/4″ Built-In ceramic fiber insulation ¼” thick standard on all Ceramic Bands will reduce power consumption by 25 to 30 percent, and lower external temperatures.

The specially designed internal brackets exert outward pressure to ensure good contact with the application surface. To aid in holding the internal components together during installation, reverse ceramic bands are supplied with a perforated stainless steel outer liner.
The outer diameter is the distinguishing characteristic and should match the inner diameter of the cylinder to be heated.
If airflow is needed for cooling, Tempco’s Type R Uninsulated Ceramic Band with a perforated sheath is also available. This is also the same robust construction that can reach higher temperatures than other heater bands.

This system was developed to reduce the cost and weight of typical shroud systems for the heating and cooling of high temperature extrusion processes.Type RCC (Rib Cage) Air Cooled Systems use multiple Type R Ceramic Band Heaters under one shroud. See also Shroud Systems.
These low mass, non-thermally insulated ceramic band heaters work in tandem with a highly efficient stainless steel sheet metal shroud and are typically arranged with spaces between the heaters to enhance the cooling of the barrel when external heat is no longer required.
Forced air blowers are used for cooling. The ambient airflow enters the shroud, circulates around the ceramic heater and barrel, removes the heat from the heater and the process and exits the shroud opposite the entrance port.
The Cool TO-THE Touch dual layer shroud uses an inner stainless steel solid layer thermally isolated from the heater, providing a path for the forced cooling air. An outer Stainless Steel perforated layer provides optimal venting and heat dissipation while providing personnel safety.

See also Shroud Systems. These low mass, non-thermally insulated ceramic band heaters work in tandem with a highly efficient stainless steel sheet metal shroud and are typically arranged with spaces between the heaters to enhance the cooling of the barrel when external heat is no longer required. Forced air blowers are used for cooling. The ambient airflow enters the shroud, circulates around the ceramic heater and barrel, removes the heat from the heater and the process and exits the shroud opposite the entrance port. The Cool TO-THE Touch dual layer shroud uses an inner stainless steel solid layer thermally isolated from the heater, providing a path for the forced cooling air. An outer Stainless Steel perforated layer provides optimal venting and heat dissipation while providing personnel safety.

These heaters use the same built-in insulation as normal ceramic bands and therefor can either reduce the power needed to heat an application to the desired temperature or offer some thermal protection to anything else that might also be inside the cylinder. Standard Insulation (S): 1/4″ Built-In ceramic fiber insulation ¼” thick standard on all Ceramic Bands will reduce power consumption by 25 to 30 percent, and lower external temperatures. The specially designed internal brackets exert outward pressure to ensure good contact with the application surface. To aid in holding the internal components together during installation, reverse ceramic bands are supplied with a perforated stainless steel outer liner. The outer diameter is the distinguishing characteristic and should match the inner diameter of the cylinder to be heated. If airflow is needed for cooling, Tempco’s Type R Uninsulated Ceramic Band with a perforated sheath is also available. This is also the same robust construction that can reach higher temperatures than other heater bands.

See Additional Options > Construction Options for more insulation options Limitations – Minimum Inside Diameter: 2″ (50.8 mm) Minimum Width: 1″ (25.4 mm) Maximum Inside Diameter: 21″ (533.4 mm) Igloo® Ceramic Terminal Covers Igloo™ Ceramic Terminal Covers consist of two individual ceramic parts. They are available with all types of insulation, construction styles, and clamping variations. Unlike conventional ceramic caps, Igloo fully insulates any standard #10 terminal lugs used for electrical hook-ups. Limitations One-Piece Band with Type T2 or Type T3 Screw Terminals Minimum Inner Diamter: 2″ (50.8 mm) Minimum Width: 1″ (25.4 mm) Two-Piece Band with Type T2 or Type T3 Screw Terminals Minimum Inner Diamter: 4″ (101.6 mm) Min. Width: 1″ (25.4 mm) Reverse Band with Type T3 Screw Terminals Minimum Inner Diamter: 5-1/2″ (139.7 mm) Three types of Igloo™ bases are available: Type C6 — Double Port In-Line P/N CER-101-104 Type C7 — Double Port 90° P/N CER-101-106 Type C8 — Single Port P/N CER-101-107 Igloo™ caps are available in the following screw terminal size: 10-32 — P/N CER-102-101 High Temperature Lead Wire When required, high temperature lead wire can be used. The wire is insulated with mica tapes over the stranded nickel conductors and then treated fiberglass overbraid. Maximum temperature: 450°C (842°F) Ground Terminal or Lead For those applications requiring a separate ground terminal or lead attached to the heater sheath. A Ground Terminal or Lead is available on any construction or termination variation. Dual Voltage Band heaters can be designed using 3-wire series/parallel circuits for dual voltage applications. Whether the heater is run on the high or low voltage, the wattage will be the same. Dual Voltage wiring is available with all types of insulation, construction styles, or clamping variations. Minimum width: 2″ (50.8 mm) Electrical Plugs Industry standard NEMA twist lock electrical connectors are available. The plugs can be attached to fiberglass leads, armor cable or wire braid. Electrical Plugs can be added to any termination variation.
