Operating your sauna
What do the 10 ozone levels on my sauna mean, and which one should I use?
The ten levels on a Salvagente ozone sauna step the generator's output by 10 per cent each, from 10 per cent to the full 500 milligrams per hour. Oxygen flow stays constant at 2 litres per minute throughout. Start new users low and raise the level gradually as they build up sessions.
What the levels control
The ten levels set how much ozone the built-in generator feeds into the sauna. Level 1 is 10 per cent of output, level 10 is the full 500 mg/h, and each step in between adds another 10 per cent. They are the same ten steps on every model, whether shown on the Standard’s digital display or the Deluxe’s 4.3-inch colour screen.
The oxygen feed does not change with the level. It is a constant 2 litres per minute, which is why there is nothing to adjust on the concentrator between clients.
What that means inside the sauna
At full output on that feed, the ozone concentration across the whole air volume inside the sauna is about 47 ppm. That is an ambient figure for the sauna, not the concentration in the delivery line, and it fluctuates with the size, build and weight of the person inside, because they displace part of the air volume.
- Ozone output (mg/h) is the mass of ozone the generator produces per hour.
- Ozone concentration (ppm) is how much of the air inside the sauna is ozone at a given moment.
Choosing a level
Build up the number of sessions before raising the ozone output, and raise output gradually rather than starting a new client near full output. The convention operators use is a 10 per cent step every couple of weeks; that is operating practice, not a clinical schedule.
Setting a client’s level, frequency and progression is a decision for the practitioner supervising them, who should hold a medical history. It is not something a client should self-adjust.
If a client develops a rash or any other skin reaction, stop — do not simply reduce the level and carry on — and refer them to their doctor before resuming.
In practice
- A client who is not sweating as expected usually needs more sessions, not more ozone.
- Level, session length and temperature are three separate settings. Change one at a time, or you will not know which one caused a reaction.
