ThermaSol Day Spa Series 20kW Steam Bath Generator

The ThermaSol DS-650 is the flagship of the Day Spa Series: 20kW of commercial steam capacity for up to four enclosures with combined dimensions from 1300 to 2600 adjusted cubic feet (ACF) — resort-scale steam from a single generator.

It runs on 240V single-phase power across two 46-amp circuits (50-amp protective devices recommended), with the same commercial DNA as the rest of the line: stainless steel inside and out, industrial-grade serviceable heating element, non-pressurized vessel, integral drain pan and included hardware kit. Installation flexibility up to 50 feet from the steam rooms keeps mechanical room options open. CSA/CUL listed with an ASME safety valve.

The complete package includes two, three or four in-room controls and commercial steamheads — one spec line covers the whole steam program.
