Induction heating generator HU 1i

The HU 1i is a modern, transistorized high-frequency generator designed specifically for applications requiring operation in the 1-3 MHz range, where previously difficult-to-find and expensive tube-based generators dominated. The device fills a gap in the market by offering precise induction heating in processes that were previously heavily dependent on tube technology, such as crystal growth, heating ultra-thin foils, and machining very small components.

By utilizing modern transistors and premium components, the HU 1i ensures stable operation over the full power range and a continuous duty cycle of 100%, even at a maximum frequency of 3 MHz. The high operating frequency enables a shallow penetration depth, making the device ideal for machining very small and delicate workpieces, including battery foils, sealing materials, electronic microcomponents, medical components, and semiconductor components.

One of the key advantages of the HU 1i is its exceptional precision in the sub-millimeter range, where many induction devices lose control and process stability. Himmelwerk designed the HU 1i as a solution that maintains excellent repeatability and dynamic power control even in the most demanding microinduction applications.

The device offers extensive integration options with industrial automation systems—interfaces including EtherCAT, Profibus, Profinet, and other communication standards are available. Combined with an intuitive, industrial-grade user interface and a startup time of just 2 seconds, the HU 1i ensures smooth implementation in both new and existing production lines.

The HU 1i is a solution designed for manufacturers and laboratories seeking the highest precision, process stability, and reliability—all in a compact, energy-efficient, and modern transistor design, providing a viable alternative to tube technology.
