ThermaSol PROI-140 Steam Generator – Compact Power for Home Steam Rooms
The ThermaSol PROI-140 is an advanced 8kW steam generator designed for residential steam rooms ranging from 85 to 140 adjusted cubic feet (ACF). Engineered for durability and high performance, it operates on 208V–240V single-phase power and delivers a premium spa experience at home.
Built as part of the trusted ThermaSol Pro I Series, the PROI-140 features all-stainless steel construction for maximum corrosion resistance and long-lasting reliability. Professional-grade heating elements ensure powerful, efficient steam output, while Fast Start technology reduces wait time, bringing your steam shower to temperature faster than traditional systems.
The split tank design enhances the generator’s life span by separating the water feed system from the heating chamber, improving efficiency and reducing wear. Intelligent CAN Bus technology enables seamless two-way communication between the generator and your selected ThermaSol control system.
The PROI-140 is compatible with a wide range of ThermaSol control options—including ThermaTouch, SignaTouch, MicroTouch, Signature Control, Easy Start, the Wellness Package, and Digital Shower Package—allowing full customization of your steam environment.
For a multi-sensory experience, the unit integrates effortlessly with Serenity Light and Music Series, HydroVive, and other ThermaSol accessories. Installation is flexible, with the ability to position the generator up to 50 feet from the steam enclosure in locations such as closets, vanities, attics, or basements.
Backed by ThermaSol’s limited lifetime warranty, the PROI-140 is fully serviceable and UL and CSA listed to ensure safe, worry-free operation.
Note: ThermaSol sizing is based on its "Simple Sizing" method, which uses Length × Width × Height (in feet) to determine adjusted cubic footage. No material adjustments are factored into this calculation.
