Mica Band Heater, Material : Metal, Mica

Mica band heater, Mica Band Heaters are constructed by winding a nickel-chrome resistance ribbon around mica insulation and encapsulated in a stainless steel sheath. It is then formed to the desired diameter for installation over a dies, barrels and nozzles. They are available in an extensive variety of sizes and shapes with options for holes, notches and cut-outs. A number of threaded terminals, wire lead options and terminal boxes offer great flexibility for field wiring.

One Piece Construction: To be used when a heater can be slipped over a barrel without having to expand the heater extensively.

Two Pieces / Multiple Segment Construction: Two piece or multiple segment bands make installation far more convenient and are recommended for applications over a 14" diameter. Spring loaded clamping is recommended.

• Ensure Heater ID same as OD of cylinder/nozzle
• Eliminate contamination of oil, plastic, dirt etc on cylinder surface to avoid carbonizing & shortening heater life
• Secure firmly to avoid Air gap and also to compensate for normal expansion, re-tighten periodically
• Maintain temperature controls & accessories in good working condition to avoid over heating condition
• Protects leads from abrasion
• Avoid process material leakage to terminal
