Backer Hotwatt Miniature Cartridge Heater

Advanced Split-Sheath Design Provides These Features:

• A high temperature alloy split-sheath with a unique ability to expand for maximum heat transfer.
• A continuous nickel-chromium resistor element. No cold spots or cold ends, as found in conventional cartridge heaters.
• Magnesium oxide electrical insulation of the highest possible density - 96% of theoretical.
• Lead connections welded to the resistor, exiting through continuous insulation that can be bent sharply at the heater without exposing the conductors.
• The result? A superior cartridge heater offering longer life, uniform temperatures, and easy installation in the tightest spots.

Benefits to Your Heating Process

• Longer Life- When energized the opposing heater legs push apart, locking into contact with the surrounding bore for maximum heat transfer. Cooler operation means longer service life.
• Easy Removal- When de-energized the heater legs contract, breaking contact for slide-out removability.  SunRods are guaranteed never to seize !
• Uniform Heating- The continuous resistor provides consistent heat along the heater body. Even the tip is heated, providing uniform heat to your process.
• Heat Wherever You Need It- SunRods can be built in lengths down to 1/2 inch.
