Product Description
White Steatite Ceramic Band Heaters for Electrical Insulation
Ceramic band heaters provide exceptional electrical insulation and thermal performance for plastics extrusion and injection molding applications. These industrial heaters feature superior insulation properties that deliver longer service life and reduced energy consumption.
Product Configuration & Specifications
Available in diameters from 2-1/4 inches and larger, with widths ranging from 1 inch to 16 inches. Standard lead exit position is 180° from the gap.
Key Advantages
Lower Operating Costs: Superior insulation minimizes heat loss to ambient air, requiring less wattage to maintain barrel temperature.
Enhanced Operator Comfort: Significantly reduced ambient heat emission compared to mica band heaters.
Extended Service Life: All materials rated for high-temperature operation ensure durability.
Higher Operating Temperatures: Capable of withstanding extreme thermal conditions.
Easy Installation: Flexible design simplifies mounting and removal procedures.
Dual Heat Transfer: Combines radiation and conduction for efficient heating without requiring perfect fit.
