The Steamist "SM" generator operates with one or two
controls appropriately located inside and/or outside the
steamroom. It's small enough in size to be tucked away
using very little space in a vanity, closet, basement, or an
insulated attic, but large enough to provide steam for most
residential baths.
The Steamist "SM"
factory-assembled carefully wired and tested.
NOTE: The TC-110, TC-135, DSC-425, and DSP
Controls are designed to work with all Steamist "SM"
Generators.
