Plastic processing requires high operating temperatures and fast production rates. Datta group has designed its ceramic band heaters to meet these demands. These heaters are, in effect, high temperatures electric furnaces capable of very efficient heat transfer by radiation, conduction and convention. 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 from 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 surface 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 simply wiring.
Features
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
ΒΌ inch of ceramic fiber prevents heat loss, thereby lowering energy costs.
3. Ceramic coil supports
Designed for their dielectric and thermo conductive characteristics, the interlocked 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.
