Solid-State Engineering Advantages

96.8% IGBT Efficiency

Solid-state resonant frequency inverter converts up to 96.8% of incoming grid energy directly into electromagnetic bath heat.

Zero Gas & Clean Shopfloor

100% flameless, zero toxic carbon emissions, and cool ambient cabinet exterior for superior operator workplace health.

Microsecond Interlocks

Ultrafast <5µs crowbar electronic protection guards against short circuit, phase imbalance, high voltage, and low water flow.

ISO 9001:2015 Verified

Every machine undergoes a mandatory 4-hour live load melt test at our Rajkot facility before wooden seaworthy crate packaging.
