Induction heating is a flameless, non-contact process that uses high-frequency electromagnetic fields to heat electrically conductive materials. When a metal part is placed inside an induction coil, eddy currents are induced within the part, generating heat due to its electrical resistance. This method is fast, clean, and highly controllable—ideal for forging, hardening, annealing, and melting.
We design and supply a wide range of systems, including:
- Induction billet heaters
- Induction hardening systems
- Induction annealing systems
- End bar heating systems
- Transformers and coils for induction heating
- DM water circulation units
- Custom control panels and inverter modules
Each system is tailored to specific industrial applications and built for performance, reliability, and energy efficiency.
Our systems are trusted across:
- Automotive and aerospace manufacturing
- Agricultural and construction equipment
- Tooling and general engineering
- Foundry and metalworking
- Pipe, tube, and wire processing
Dayalu Induction systems are engineered for high thermal efficiency. With optimized coil geometry, resonant tank circuits, and smart power control, our machines deliver maximum heat per kilowatt—resulting in significant unit savings and lower electricity bills
Our machines operate with a *power factor close to 1.0*, ensuring minimal reactive losses and optimal utilization of supplied power. This improves energy efficiency and helps avoid penalties from utility providers—making your operation grid-friendly and cost-effective.
We use PLC-based automation only when required by the application. Most of our systems are built around custom controller-based circuit boards, which handle automation, timing, feedback, and interlocks internally. This approach reduces complexity, lowers cost, and ensures faster response times—while still allowing PLC integration when needed.
We use DM (Demineralized) Water Circulation Units* to cool coils, transformers, and power electronics. These closed-loop systems prevent scaling, corrosion, and electrical conductivity—ensuring safe and continuous operation in high-load environments.
Yes. We specialize in application-specific system design*. Whether you need localized heating, long bar processing, or integrated automation, we tailor every system to your material, geometry, and production flow.

IGBT stands for Insulated Gate Bipolar Transistor. It’s a high-efficiency semiconductor device used to switch and control high-frequency power in induction heating systems. IGBTs combine the fast switching of MOSFETs with the high current handling of bipolar transistors—making them ideal for delivering precise, reliable, and energy-efficient heating.
IGBT systems offer:
- High energy efficiency (often above 90%)
- Precise temperature control with fast response times
- Compact and modular design for easier integration
- Stable performance under varying loads
- Reduced maintenance compared to older SCR or tube-based systems
