The 12kW Heating Element (480V/3PH) restores consistent steam output to Mr.Steam commercial CU-series generators configured for 480-volt, three-phase power. This element boils tank water to build the pressure and volume needed for reliable steam production, and like any heating element, it's a wear item — calcification and lime buildup over time will eventually require replacement. Depending on the generator model, one or more elements may work in combination to reach full system output, so confirming the exact element configuration before ordering helps avoid installation delays. Built to match factory specifications for CU-series commercial units, this replacement element restores full heating performance without adapters or modifications. It ships with a gasket kit for a proper, leak-free installation, and its rugged construction is built to withstand the sustained heat and humidity of continuous commercial steam operation. Keeping a spare on hand as part of a routine preventative maintenance program helps facility operators minimize downtime from unexpected element failure.

  • 12kW Output, 480V/3PH – Sized and configured to match CU-series generators running on 480V three-phase power, restoring full-rated heating capacity.
  • Installation Hardware Included – Ships with a gasket kit, simplifying a proper, leak-free installation without sourcing separate parts.
  • Model-Specific Fit – Used in quantities of 1 or 2 depending on generator model (e.g., single element in CU500/CU1250/CU2000, paired elements in CU1000/CU2500) — confirm configuration before ordering.
  • Wear-Item Replacement – Recommended to keep a spare on hand as part of routine preventative maintenance, since calcification and lime buildup are expected over time.
  • Commercial-Grade Construction – Built for the continuous-duty demands of Mr.Steam CU-series commercial steam bath generators.
