Model NumberPRO-850

Create your very own “at home spa experience” with a Steamshower generator. The unique steamshower system transforms your ordinary shower into a deluxe steam room, creating a wonderful daily ritual, while enhancing your well-being and relaxation. The Thermasol SmartSteam System, available in the ProSeries generators, is brilliantly designed to produce the exact amount of steam required to keep your room at optimum temperature while conserving energy and maintaining the peaceful ambiance, with constant heat at a constant rate. Never suffer again from annoying temperature fluctuations. Treat yourself to the absolute ultimate in comfort and luxury all in your very own bathroom!

Calculate the length x width x height in order to measure the cubic feet of the room and to determine which generator is right for you. For every foot of ceiling height over 8 feet use the next larger steam generator.

Electrical Specifications:

  • Cubic Feet: 850
  • AMP 240
  • VAC: 110
  • Wire: 0
  • Breaker: 120
  • Phase: 1
  • kW: 24

Features and Benefits:

  • Patented SmartSteamTM - The SmartSteam technology produces the precise amount of steam required to keep the rooms at ones optimum temperature while conserving energy and maintaining the relaxing environment with whisper quiet utility.

  • Whisper Quiet - Since ThermaSol units do not use a solenoid valve to replace the water boiled away there is no potential for water hammer, none. This allows the steam bath experience to be what it was designed to be; a relaxing getaway that allows you to rejuvenate from the daily pressures we face in a world that appears to move faster every day

  • Constant steam at a constant rate

  • Fast StartTM - Fast Start provides steam in less than a minute. It is energy efficient but can be turned off as needed.

  • Auto PowerFlushTM pressurized inner tank cleaning system- PowerFlush was specifically designed to purge calcification build-up from the inner-tank. This unique system uses a combination of household water-line pressure (40 to 80 lbs) and specially designed inner-tank “speed slots” to increase the water pressure. This water pressure effectively sweeps the bottom of the tank removing build-up.

  • Digital CAN-bus networked system, intelligent two way communication

  • Can be plumbed 50 ft. from the shower without purchasing a larger kW unit

  • Superior heating elements - low watt density

  • Split tank enhances performance and life-span - Water is preheated in the water reservoir and passes to the boiling side only at the exact rate of steam production. This efficient system delivers uninterrupted boiling, providing constant steam flow at a constant rate. This unyielding steam production allows you to install the steam shower generator up to 50 feet away from the shower enclosure without purchasing a larger generator. Because the water feeder is removed from boiling process it extends the life of your steam shower generator and limits calcification build-up, ensuring trouble free reliability for life!
