Kilns and furnaces are primarily resistive (heating element) loads, not motor loads. They don't spike at startup the way motors do, making sizing simpler and more predictable.
Balanced Output Matters
Unbalanced three-phase output causes uneven heating and premature element failure. Phoenix balances output within 3% leg-to-leg under load.
Ceramic & Glass Kilns
Skutt, L&L, Olympic, and Paragon kilns run 3–20 kW. We match the converter to your kiln's kW draw and phase configuration.
Heat-Treat & Induction Heaters
Industrial heat-treat furnaces and induction heaters can draw 20–100+ kW. We size for the full draw with thermal protection for continuous firing cycles.
