Plastic processing requires high operating temperatures and fast production rates. We have designed ceramic band heaters to meet these demands. These heater are, in effect, high temperature electric furnaces capable of very efficient heat transfer by radiation, conduction and convection. Built-in insulation minimizes unwanted temperature changes along the barrel.

Other types of band heaters are primarily conductive, requiring an intimate fit with components being heated. Grooves or other surface irregularities form voids under the bands, resulting in hot spots and premature heater failure.

Ceramic bands are recommended here because efficient heat transfer is not affected by irregular surfaces or loose fit. At higher watt densities they can be used in wider increments than other heaters. This means you can reduce the number of bands used and simplify wiring.

"THE PREFERRED CHOICE OF OEM’S"

1. Stainless steel sheath
   Resists rust and high temperatures, and provides firm mechanical support. Easily wraps around barrel due to fluted construction.
2. Thermal insulation
   ¼ inch of ceramic fiber prevents heat loss, thereby lowering energy costs.
3. Ceramic coil supports
   Designed for their dielectric and thermoconductive characteristics, the interlocking feature provides flexibility so band wraps easily around barrel.
4. Nickel-chrome heating coil, precision wound, helical construction gives extended service. A heavier weight than found in mica or other conventional heaters.

Insulation Plus - The Energy Saver

1. Insulation Plus employs an additional 1/4" of thermal insulation encased in a separate flexible stainless steel shell.
2. Standard 1/4" thick thermal insulation found on all ceramic band heaters.
3. Helical nickel-chrome coil for extended service.
4. Ceramic coil supports.

"MAXIMUM ENERGY SAVINGS, MINIMUM SHEATH TEMPERATURES"

High performance heater band for processing high temperature engineering resins. The first improvement in ceramic heaters since the introduction of"Insulation Plus"TM in 1975. "Ultra-Thin" heater bands have the same basic construction as our standardceramic heaters except they are much thinner and have a high ratio of thermal to electrical insulation. The thin ceramic insulation’ used results in a lower mass construction, which improves response to control and minimizes temperature lag and overshoot.

The backside thermal insulation is highly efficient and results in minimal heat loss and lower sheath temperature. The "Ultra-Thin" has averaged 100 deg. F lower sheath temperature when tested against other high temperature heaters at 600 deg. F cylinder temperatures. The "Ultra-Thin" without thermal insulation and with a perforated sheath is ideally suited for air cooled systems.

"Ultra-Thin" heaters are constructed of all high temperature materials. The heater element itself is computer designed for maximum wire size which results in a long service life. Developed primarily for high temperature, high watt density plastic processing machinery, this premium performance heater can be used in many other applications.

Special Note:
These are completely flexible radiant heaters. Heavy clamping pressures are not required regardless of heater size. No need for hinged, two piece, or expandable designs associated with mineral insulated (MI), mica or other conduction type heaters.
