Did you know that whatever your design or engineering challenge is, Backer Hotwatt has the expertise and broad technology base to develop a customized and dependable product for your unique needs? Whether you are heating air, fluids, gases, or other surfaces, our engineers can develop a solution that helps your application function most efficiently. 

What we like best about our revolutionary SunRod mini cartridge heater is that it allows us—and you—to solve tough challenges for vast applications.

This patented high-temperature heater offers longer life, uniform temperatures, and easy installation. Its design provides these advantages:

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

All heater designs are computer-generated to ensure consistent quality from lot to lot. Additionally, every unit is subjected to stringent in-process testing and multi-point quality assurance tests prior to delivery.
