| Band Heater Types and Specifications |
MI Band Heaters Mineral insulated heater assembly is formed under pressure to a precise diameter with a thin low-mass cross section assuring fast heat-up rates and reduced cycle times. PERFORMANCE RATINGS Max. Sheath Temperature: 1400°F (760°C) Nom. Watt Density: Nozzle Bands – under 3” dia.: 30-100 W/in² (4.7-15.5 W/cm²) Barrel Bands – 3” & greater in dia.: 20-70 W/in² (3.1-10.9 W/cm²) Max. Watt Density: Dependent on application. Mica Band Heaters A mica insulated heater incorporating a low thermal expansion alloy outer sheath that is used as a uniquely designed built-in strap. PERFORMANCE RATINGS Max. Sheath Temperature: 900°F (482°C) Nom. Watt Density: Nozzle Bands – under 3” dia.: 20-55 W/in² (3-8.6 W/cm²) Barrel Bands – 3” & greater in dia.: 20-45 W/in² (3-7 W/cm²) Max. Watt Density: Dependent on application. Maxiband® Heaters The channels in the specially designed extruded aluminum track have been precisely sized to accept a .315 diameter tubular heating element, and provide an excellent heat sink for rapid heat transfer and good temperature uniformity. PERFORMANCE RATINGS Max. Temperature: 650°F (350°C) Nom. Watt Density: 25-35 W/in² (3.8 – 5.4 W/cm²) Max. Watt Density: Dependent on application. Ceramic Band Heaters Ceramic Band Heaters consist of a helically wound resistance coil made from nickel- chrome wire precisely strung through specially designed ceramic insulating bricks, forming a flexible heating mat. PERFORMANCE RATINGS Max. Sheath Temperature: 1400°F (760°C) Nom. Watt Density: 20-45 W/in² (3-7 W/cm²) Max. Watt Density: Dependent on application. Tubular Band Heaters Tubular Band Heaters are recommended for heating applications where premature nozzle band heater burn-out on plastic injection molding machines is a constant problem due to contamination from plastic overflow or other contaminants. PERFORMANCE RATINGS Max. Sheath Temperature: 1000°F (540°C) Nom. Watt Density: 40 W/in² (6.2 W/cm²) Max. Watt Density: Dependent on application. |
