Coiled Tungsten Heater
1. What Is a Coiled Tungsten Heater?
A coiled tungsten heater is a tungsten heating element fabricated by continuously winding high-purity or doped tungsten wire into a multi-turn coil configuration. This structure increases the effective resistance length and heating density per unit, providing a stable thermal output suitable for vacuum applications requiring continuous or cyclic heating.
2. Features of CTIA’s Coiled Tungsten Heater
The continuous multi-turn structure facilitates a uniform current path distribution, resulting in a consistent heating process. Critical manufacturing factors include precise tension and spring back control during the winding process, which determine coil consistency and shape retention at elevated temperatures. Proper process management reduces the risk of deformation, localized collapse, or uneven heating caused by residual stress, thereby supporting operational stability and extended service life.
3. Applications of CTIA’s Coiled Tungsten Heater
（1）Continuous or zoned heating elements within industrial furnaces.
（2）Evaporation sources and auxiliary heating components in vacuum coating systems.
（3）Stable heating zones for vacuum heat treatment processes.
（4）Continuous production cycles sensitive to thermal fluctuations.
（5）Linear or localized stable heating in high-temperature vacuum environments.
