Description

The ThermaSol PROIII-140 is a professional-grade 8kW steam generator designed for residential steam rooms ranging from 85 to 140 adjusted cubic feet. Operating on 208V-240V single-phase power, this unit delivers consistent steam output through Smart Steam temperature control, eliminating fluctuations and delays. Fast Start technology accelerates heat-up times, while the split tank design separates heating and water feed functions to maximize durability. The PowerFlush pressurized cleaning system prevents sediment accumulation and extends equipment life. Built with stainless-steel construction and advanced CAN Bus technology, the PROIII-140 integrates seamlessly with ThermaSol's control systems including Thermatouch, Signatouch, and Digital Shower packages. Installation flexibility allows placement up to 50 feet from the shower enclosure in closets, cabinets, attics, or basements. Compatible with premium accessories like Serenity, Light, and Sound systems, this unit combines engineering precision with long-term reliability, backed by ThermaSol's limited lifetime warranty and UL/CSA certification.
