Mr. Steam Element MS 12kW 240/3 is a genuine, high-capacity replacement built to restore factory performance in MS Series—particularly MS Super 2—steam generators running on 240V three-phase power. Delivering a full 12 kW of heating, it brings larger or heavily tiled enclosures to temperature quickly and sustains dense, even vapor for consistent comfort. The 5 lb assembly is engineered for steam-room realities, using steam-rated, corrosion-resistant construction and robust terminations that stand up to heat, humidity, and repeated thermal cycling. A true OEM-style fit aligns with existing control logic and mounting geometry, enabling a clean, plug-and-play install that preserves safety interlocks and minimizes downtime. Balanced three-phase delivery enhances electrical efficiency, reduces voltage sag and nuisance trips, and helps prevent overshoot or short cycling—keeping your Mr. Steam system running reliably session after session.

  • 12 kW steam performance – High-capacity heating delivers rapid warm-up and dense, even vapor for larger or heavily tiled enclosures. Abundant output maintains target temperatures, minimizes recovery time, and elevates comfort for a smooth, spa-quality experience across long sessions.
  • 240V three-phase efficiency – Optimized for 240V/3 power to balance electrical load across legs for cooler operation and stable voltage. Consistent supply reduces nuisance trips and sag, supporting reliable steam production and responsive control during warm-up and peak demand.
  • Seamless MS Series fit – Precisely tailored to Mr.Steam MS systems, matching interfaces and control logic for clean, plug-and-play installation. Native compatibility preserves intended features, simplifies commissioning, and avoids adapters or rewiring that can complicate service or introduce faults.
  • Durable, steam-rated construction – Built to withstand sustained heat, humidity, and mineral exposure inside generator bays. Corrosion-resistant components and secure terminations protect critical elements, extend maintenance intervals, and ensure dependable performance in demanding residential or light commercial environments.
  • Consistent, energy-savvy operation – Balanced thermal response sustains comfortable vapor density without overshoot or short cycling, helping reduce energy waste while keeping sessions steady. Predictable performance improves user comfort from start-up through the final minutes of every steam.
