U.S. Solid 15KW Induction Furnace (30-80KHz, 16:2, 220V)

Better for operations needing higher power output with similar frequency. This unit emphasizes energy savings and reduced electrical load while offering continuous full-load operation. Best for shops requiring reliable, long-duration heating without frequent downtime. Limitation: a higher current draw may require upgraded electrical service.
U.S. Solid 15KW Induction Heater (110V, 30-80KHz, 16:2)

Choose this if you operate at 110V and need dependable heat for metal melting and processing. It matches the 30-80KHz range with a 16:2 turns ratio, aiming for stable output and energy efficiency. Caution: ensure your site voltage is stable to avoid voltage fluctuations affecting performance.
JIANGYUXINLI 15KW Induction Forge (110V/220V) 30-100KHz

Best for versatile coil setups and rapid heating with 30-100KHz range. The two-coil kit supports flexible application in forging, brazing, and heat treatment. Limitation: international shipping may require crates and longer lead times; confirm coil compatibility with your piece parts.
CHMING 15KW High Frequency Induction Machine (220V, 30-100KHz)

Choose this for a stainless-steel shell and high current output (200-600A). The 30-100KHz range supports versatile heating, annealing, and brazing. Caution: ensure adequate water cooling flow and protective measures to maintain safe operation during continuous use.
Buying Guide: Key Purchase Considerations
- Voltage compatibility: Match the unit to your shop’s electrical service (110V vs 220V) to avoid costly upgrades.
- Frequency range and turns ratio: Higher frequencies can deliver faster, localized heating; turns ratio affects voltage/current distribution to coils.
- Continuous operation capability: Look for 100 percent full-load ratings for demanding production environments.
- Cooling and protection: Water cooling and automatic over-current/over-voltage protection reduce downtime and component wear.
- Coil options: Some models include coils; verify coil compatibility for your parts and geometry.
- Build quality and durability: A stainless steel shell or industrial-grade components improve long-term reliability in workshop settings.
Frequently Asked Questions
- What does 15 kW indicate for an induction heater?
– It represents the maximum output power the unit can deliver for heating metal, influencing heating speed and depth. - Can these heaters run continuously?
– Many models specify 100 percent full-load operation, meaning they are designed for constant use in production, with proper cooling. - Which voltage is best for small shops?
– 110V models are more common in small spaces; larger shops often use 220V for higher power and efficiency. - Is a higher frequency always better?
– Not always. Higher frequencies heat surface layers quickly but may require precise coil and part geometry; lower frequencies penetrate deeper. - Do these units include cooling systems?
– Most require water cooling to maintain safe temperatures; verify cooling specifications and flow requirements. - What should I check before purchasing?
– Check voltage availability, coil compatibility, cooling system, continuous operation rating, and warranty terms.
