Ceramic Heater Bands

5 Styles to Choose From • Energy Saving • Up to 65 Watts/Sq. In.
STANDARD - 5/8" thick, ¼" thermal insulation, up to 1400 F, 45 watts/sq. in.
Plastic processing requires high operating temperatures and fast production rates. Omega has designed its 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"
OMEGA QUALITY CONSTRUCTION

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.

WHEN ORDERING, PLEASE SPECIFY:
Quanity
Inside diameter & width
Voltage - on 2 piece bands we suggest each piece be rated at half the operating voltage, please specify total voltage
Wattage - on 2 piece bands please specify total wattage
Basic construction and options
Serial no. (If known or previously ordered)
Gap (if other than factory minimum)
Lead length (If other than std. 12")
Maintenance and trouble shooting for prolonging heater life
1. Regulate Voltage. A 10% variation in voltage results in a 20% variation in power.
2. When attaching the lead wire to the terminals, excessive turning pressure can cause breakage of the terminal resistance wire.
3. A ¼" gap should be maintained at the opening when operating. Retightening is not normally required, however, if the operating temperature is changed the clamp bolt should be checked.		 4. Any material which can be carbonized such as dirt, oil, plastic, etc., should not be allowed to collect on the heaters.
5. Select a heater to match the diameter of the cylinder. In no case should heaters be used that are too large.
6. Match the heaters as closely as possible to the actual load requirement to reduce cycling.
