Digital Steam Generator Installation and Technical Overview
Classic Steam generators complete with all wiring, digital controls and steam heads.
Steam Generator Body
Steam Control Panel
Easy Access Digital Controls. (Preferably situated outside of steam room)
Thermostatically controlled temperature settings
Self-cleaning (auto-purge) occurs at the end of each operating cycle,
Latest unique qualities:
Patented new design where heating elements no longer come into direct contact with the water.
Separating the elements from the water, extends the lifespan of the heating elements significantly.
Steam output is increased by 20-30% over that of the traditional style. This results in overall more energy efficiency.
An electronic pressure protection device, has been added as a 2nd fail-safe mechanism, over and above that of the standard mechanical pressure relief valve.
An automatic electric drain enables the water to be drained more thoroughly than that of the traditional solenoid valve.
A 100 mm width slim design, makes the installation more flexible.
Steam systems can be customized to suite various concepts.
Both the generator and control panel have been CE (European) and UL (USA) approved and meets the respective safety requirements.

Steam generator installation dependencies:
It is the responsibility of the project manager/owner builder to ensure that the steam generators pre-requisite water, electricity and waste services are compliant before any installation of generator is initiated.
for 9 Kw three phase steam generators, use 2.5mm Surfix, 20 amp 3 phase @ 220v
for 9 Kw single phase steam generators, use 6mm Surfix 35 amp 1 phase @ 220v to Isolator.
The isolator should be within 1 m of the steam generators final location.
Earth leakage should be via an appropriately rated circuit breaker (i.e 20, or 35 amps as above, 3 pole if necessary) in main distribution box.
Water supplied via a stop-cock with a 15 mm (1/2 inch BSP) male threaded connection, within 1 m of the generator.
Waste Drain Pipe:
15 mm pipe from steam generator location to waste to allow for the “auto-purge” (drain) function to operate.
22 mm Class 1 copper pipe/s to fall or rise continuously from generator location to the steam outlet.
Steam outlet should emerge +- 200 mm above the tiled floor, flush with the walls tiled surface.
Ensure no 'WATER TRAPS' in the steam pipe are in existence. These could fill with (condensed) water, and could block the flow of steam.
Steam pipes should terminate in 22 mm female threaded connections.
A Chrome steam-head deflector will be supplied, which will connect to the above 22 mm female threaded connection, using 22mm threaded brass nipples, cut off at an appropriate length.
Steam pipe outlets should be located at an area furthest away from any bathers feet, ideally at the opposite end of the steam room.
Conduit for Digital control wires:
The Digital Control Panel fits into a wall outside of the steam room.
32 mm conduit (with pull wire) to run from the above Digital Control cavity to steam generator location. (See diagram above)
Large 32 mm conduit is required since the control wires have large connectors that need to be pulled through the conduit.
Conduit for Temperature control probe:
20 mm conduit (with pull wire) to run from Digital Control location (outside of steam room) to inside of steam room, where a metal temperature probe will protrude slightly through the ceiling OR wall tiles.
How to Build your own Steam Room ( DIY ):
Although there are a number of ways to build a steam room, we recommend following the process below:
Steam Generator location:
Install steam generator in a dry well ventilated area (outside of steam room). An ideal location is near the steam room, such as cabinet, closet, basement, under stairs, in roof cavity or above steam room.
Walls and Benches:
A steam rooms walls can be constructed of tiles and/or glass. The glass component can be aluminium or frame-less glass.
Under the surface of tiles should be thoroughly waterproofed.
Benches should be sloping forward slightly so as to not collect water.
Dual level benches are preferable, as wide as possible.
Drain on floor should exist to facilitate cleaning of steam room.
A suggestion is to include the standard shower functionality of shower water roses and hot/cold water mixers.
Steam Room Ceiling should be as LOW as possible (+- 2100 mm average height) since most heat will rise.
Ideally a slanted ceiling should be installed, high end at the benches, sloping towards the area where there are least benches.
Ceiling can be constructed of “smooth Nutec sheeting” (by Everite Company ), on perlins or brandering.
Ceiling can be waterproofed by painting with Plascon waterproof primer and two coats Plascon Velvaglo, preferably using roller.
Nutec sheeting is preferred since it is:
inexpensive and readily available,
not affected by moisture and will not rot,
cannot be damaged by termites or rodents,
is non-combustible and is relatively strong in its own right.
can be supported on light gauge metal frames or light timber structures.
can be suspended with anodized (or powder-coated) aluminium rails or used with H-profiled “Nutec jointing strips”.
Glass or Polycarbonate ceiling can also be constructed to allow light to permeate into the steam room from an existing light source.
A low-voltage (12V AC) waterproof mood-light (down-light) can be installed in the ceiling.
Light switch should be outside the steam room.
Steam room doors should always open outwards
Door seals should be tight fitting to avoid steam escaping and causing damp problems.
