Mr. Steam MX4E Steam Generator, Single Phase, 20kW

Mr.Steam MS generators , Model MX4E

The Mr.Steam E-Series MS generators are crafted from recyclable stainless steel and assembled with meticulous attention to detail. Compact, easy to install, and about the size of a large briefcase, Mr.Steam MS generator installs up to 60 feet away in areas such as a cabinet, closet, under a sealed bench, or in an insulated attic.

Exclusive microprocessor operating system is the brains of the intelligent Mr.Steam MS generator. The automatic water control maintains constant steam by introducing just the right amount of water through a proprietary dispersal chamber while the water solenoid technology ensures that the generator is whisper-quiet and never hammers or hums.

Designed to save water and energy, Mr.Steam MS generator uses less than two gallons of water compared to 40 gallons for an ordinary bath. Built with 100 percent recyclable surgical stainless steel, it is naturally corrosion resistant. The reliable, industrial grade, and the industry’s largest copper heating element, heats fast, and is easy to remove and service. Safety first with the 75 minute automatic cutoff, low voltage board, designed for easy access, and safe service. LED indicators to help you troubleshoot any connection and maintenance challenges. Plug & Play Steam shower accessories or spa therapy components such as AromaTherapy, ChromaTherapy, SteamLinx, and more, are easily installed. All MS generators work with all Mr.Steam Controls and with the SteamLinx Mobile App.

Unmatched high quality construction, UL listed in the US and Canada and CE and NOM certified for unsurpassed safety. With limited lifetime warranty, it is free from defects in materials and craftsmanship for its lifetime. Mr.Steam will repair or replace (at its option) a generator which fails to conform to this warranty.
