Stiefel Induction Heaters: Energy-Efficient Solutions Since 2013

Ultra High Frequency (UHF) induction heaters operate at the very highest end of the induction spectrum, typically from 300 kHz up to several MHz. These extremely high frequencies produce an extremely shallow skin effect, concentrating nearly all the thermal energy within a fraction of a millimeter of the surface. This makes UHF technology exceptionally specialized for applications requiring intense, hyper-localized surface heating. It is indispensable for the surface hardening of very fine components like razor blades, surgical needles, and the tips of cutting tools, where only the sharpest edge needs to be hardened. UHF is also used in the growing field of crystal growth (Czochralski process) for semiconductors, where it provides the precise and controlled heat needed to melt the source material. Due to the technical complexities of generating and managing such high frequencies, UHF systems are highly specialized. Stiefel Combustion has the engineering capability to address these demanding applications. If your project involves precision surface engineering on a microscopic scale or other highly specialized thermal processes, we recommend contacting our technical experts to discuss the feasibility and specifications of an ultra high frequency solution.
