Mr. Steam Element MS 12kW 208/3 is a high-performance OEM replacement heating element built for MS Series steam generators—specifically MS Super 2 models—operating on 208-volt three-phase power. Delivering a robust 12 kW output, it provides rapid warm-up and sustained, even vapor distribution for larger or tiled enclosures, maintaining steady temperatures and superior comfort through long sessions. The heavy-duty 5 lb construction is built from steam-rated, corrosion-resistant materials that withstand continuous heat, humidity, and mineral exposure inside generator bays, ensuring long service life and stable operation. Optimized for 208V/3 electrical systems, it balances load across legs for cooler, more efficient performance and reduced voltage sag. Engineered with Mr. Steam’s native interfaces and control logic, the element installs cleanly with plug-and-play compatibility—no rewiring or adapters required—making it the reliable choice for maintenance, replacement, or system upgrades in demanding residential or light commercial applications.

  • 12 kW steam performance – High-capacity heating drives rapid warm-up and dense, even vapor for larger enclosures. Consistent output maintains target temperatures, minimizes cold spots, and elevates comfort throughout extended sessions for a noticeably smoother, spa-quality experience.
  • 208V three-phase efficiency – Optimized for 208V/3 electrical service, balancing load across legs for cooler operation and reduced voltage sag. Stable power delivery supports reliable steam production, fewer nuisance trips, and responsive control behavior during warm-up and peak demand.
  • MS Series native fit – Precisely engineered for Mr.Steam MS systems with matched interfaces and control logic. Plug-and-play integration preserves intended features, speeds commissioning, and avoids adapters or rewiring that can introduce faults or complicate future service.
  • Durable, steam-rated construction – Built to endure sustained heat, humidity, and mineral exposure inside generator bays. Corrosion-resistant components and secure terminations protect critical elements, extend service intervals, and ensure dependable performance under frequent residential or light commercial use.
  • Installer-friendly setup – Clear connections and an accessible layout simplify replacement or upgrades, minimizing downtime. Efficient routing keeps cabling tidy and service points reachable, helping technicians restore full functionality quickly and maintain peak performance with routine inspections.
