Stiefel Induction Heaters: Energy-Efficient Solutions Since 2013

Energy efficiency is a fundamental design principle behind Stiefel Combustion's induction heating systems. Our energy-saving induction heaters are engineered to convert electrical input power into useful thermal energy within the workpiece with maximum efficiency, significantly reducing operating costs and environmental impact compared to traditional heating methods like gas ovens or resistance furnaces. This high efficiency is achieved through several key technologies: advanced IGBT (Insulated-Gate Bipolar Transistor) power semiconductors that minimize switching losses, resonant inverter circuits that optimize power factor, and specially designed induction coils that maximize the electromagnetic coupling to the part. Furthermore, because induction heats the target directly and instantly, there is no energy wasted on heating the surrounding air or furnace linings. The on-demand nature of the process means energy is only consumed when a part is being heated, unlike continuously fired furnaces. This makes induction heating exceptionally efficient for batch processes or production lines with variable throughput. The cumulative energy savings can be substantial, leading to a rapid return on investment. Our team can provide a detailed energy analysis for your specific application to demonstrate the potential cost savings.
