The ThermaSol DS-400 is the 16kW workhorse of the Day Spa Series, engineered for professional day spas and resorts running up to four steam enclosures with combined dimensions from 575 to 1600 adjusted cubic feet (ACF).
High performance and low maintenance drive the design: durable stainless steel construction inside and out, an industrial-grade serviceable heating element in a non-pressurized vessel, and electronics specified for continuous commercial duty. The integral drain pan with 3/4″ NPT fitting, included hardware kit, and up-to-50-foot installation distance from the steam rooms make mechanical planning straightforward. CSA/CUL listed with an ASME safety valve.
Ships as a complete multi-room package: one generator with your choice of two, three or four in-room controls and commercial steamheads.
