Note: This model is 460 VAC, 50/60Hz, three-phase.

IHG series 100 kHz to 1100 kHz high frequency induction heaters are among the latest products developed by Across International. They can quickly heat most metals that other frequencies cannot heat efficiently, such as aluminum and metal powders, and they can also heat parts from a distance.

These heaters are designed for applications such as fine steel wire annealing, small precision shaft quenching, hard alloy saw blade brazing, and metal powder melting. Induction heating creates heat inside the workpiece itself, which supports fast, localized, and repeatable heating without direct flame contact.

Safety Features

• Overvoltage protection: machine shuts down when input voltage exceeds 245V and resets automatically once voltage returns to range.
• Overheat protection: if the IGBT heat sink exceeds 55C, the machine shuts down until cooling conditions improve.
• Overcurrent and malfunction protections: machine shuts down if components overheat, interfering signals are detected, work pieces short against induction coils, machine failure occurs, coils touch each other, input voltage is too low, or water pressure drops below 29 PSI.

Important

• Always wear protective gear and goggles when operating the machine.
• Crucibles must remain covered during operation.
• Do not run no-load operation for long periods.
• Circulating water must be pure, clean, and below 45C.
• The machine must be properly grounded at all times.
• Thread tape or similar material is prohibited during induction-coil installation.
