SunRod Micro-Cartridge Heaters

SunRod Micro-Cartridge Heater: Precision, Performance, and Reliability

The SunRod micro-cartridge heater delivers precise, uniform heat for demanding applications in industries such as medical devices, semiconductors, 3D printing, and aerospace. Its patented split-sheath design ensures maximum heat transfer and longer operating life-over 25,000 hours in many cases-while making installation and removal fast and hassle-free.

Key Advantages

• Patented split-sheath: When energized, it expands into contact with surrounding bore for maximum heat transfer, fast response.
• Easy, slide-out removal: When de-energized, the split-sheath contracts for easy removal; guaranteed never to seize in the bore.
• Fully heated tip: Uninterrupted hot zone provides unmatched heat distribution without cold spots.
• Slender continuous leads: Simplified wire management; high flexibility allows free motion when heating “floating” components.

Easy Customization and Quality Assurance

Every SunRod heater is built to your specifications and tested at multiple points during production for dependable, repeatable performance. Backer Hotwatt’s engineering team can help you select or design the right heater for your application, whether you’re heating air, fluids, gases, or surfaces.
