Here at Salvagente we don’t just sell ozone saunas, we offer complete peace of mind whether you are in need of marketing support for your clinic, questions on specific diseases and even to keep you informed.
This article is again a stark warning to any and all owners of ozone steam saunas. It came to our attention that the regulatory body of the industry, the Ozone Association of South Africa (OASA), issued an invitation to their members that the OASA will be conducting servicing of the ozone saunas in South Africa, and everyone who wishes can let their machine be checked out by a trained technician from Cape Town. Further the Chairlady of the OASA, Michelle Nicolopulos, stated that ozone generators should be calibrated every 18 months.
This is in fact a unsubstantiated claim as we have no knowledge that an ozone generator can be calibrated. This is a picture of a commonly used ozone generator and it’s visible that there’s NO places to adjust or “calibrate” the ozonator.
We further consulted a leading manufacturer of ozone related products and the engineers also have no knowledge that ozone generators can be calibrated.*
The largest manufacturer and importer of ozone products in SA (commercial and industrial) had this to say in an email directed at the OASA:
I really am curious as to how you “calibrate” an ozone unit.
If you want to measure the ozone output you require a BMT or equivalent ozone analyser costing in the region of R75000.00.
We have one of these but it is only practical on machines above 100 grams per hour and certainly not 500 mg/hr.
For the Ozone Association to be endorsing one particular supplier and with false offers will be extremely dangerous for the Association and for the members*.”
We also wanted to find out who the technician named “Brandon” – who will carry out these service and repair jobs – is, but none of our industry partners have ever heard or has any knowledge of him.
If you bought an ozone sauna from Salvagente, please do not make use of this solicitation from the OASA as this will render any warranties null and void. If your sauna is out of warranty and someone else works on it, additional rectification charges may apply if we need to service the sauna. If you are experiencing any problems with your equipment rather contact us for assistance.
This might be an uneducated attempt by the Ozone Association to assist sauna owners or it might be a mechanism to create additional funds from false claims, whatever the case we strongly advise to ignore the invitation.
Please contact us should you have any questions.

Official response of the Ozone Association of South Africa:
“On behalf of OASA, I would like to apologise for the confusion around a recent email concerning the Servicing and Calibration of Medical Ozone Generators. It has been brought to my attention that the previous email could cause confusion, and I would like to clarify this urgently.
It is a legal and ethical requirement that Medical Ozone Generators must be serviced and calibrated every 12 – 18 months. These units are NOT the same as the Ozone Saunas.
If you have an ozone sauna that has been supplied by Salvagente (OASA Member) or any other supplier, please contact them for after-sales servicing or routine maintenance to make sure your unit is working as originally sold.
with regards, Dr Julian Holmes, Scientific Advisor to OASA”
Right of response exercised by Ozone Services Industries in relation to Medical Ozone Generators:
“Ozone in commercially available units is produced by using cold spark corona through glass or ceramic dielectrics.
In respect of calibration I have spoken to Michelle and mentioned that she may have misunderstood in that ozone sensors and monitors have to be calibrated once per year and there is no way to calibrate an ozone generator. If so what are you going to calibrate against?
The only measurements are ozone out put in mgs per litre and ozone concentration by weight. Normally an air fed system will have a concentration of anything from 1/2 a percent to 3% depending upon moisture in the air and an oxygen fed ozone generator typically would provide up to 6% concentration. However some of our larger plants such as the 30 kg/hr unit at Roodeplaat and the 300 kg/hr unit at Sappi Ngondwana operate at 12% concentration as they want to bring down the oxygen costs.

Right of response exercised by Sauna Engineering Development in relation to Medical Ozone Generators and reference made to Longevity:
Upon stripping and dismantling a Longevity Ozone Sauna, this was found regarding any calibration of the ozone generator.
Disclaimer: This is not intended to discredit Longevity ozone saunas in any form or matter, merely as evidence that no calibration can take place with the ozone generator!
Updated response from the Ozone Association of South Africa regarding specific devices classified as “Medical Ozone Devices:
The following reference is made to clarify exactly what type of ozone machine the OASA indicated should be calibrated.
“Below is a selection of ozone units that would fall into the Medical Device category; it is not exhaustive and can never be, and as new devices come onto the market, how they are classified will be determined on what claims are made, how ozone is delivered, and what the units are designed for.
Currently I know that some of OASA members use the following devices;
www.medozons.com/ Medozons; Medical Ozone Units; CE & MD Marked
www.healozone.de/ HealOzone 1, 2, and 4; CE & MD Marked
www.greycellenterprises.com/ Ozi-Cure, CMU3, CMU4 ver 1&2; CE & MD Marked
The Longevity units are not specifically MD Marked, but are considered to be ‘Medical Devices’ within the legal frame work that currently exists and calibration is required. WHY? Because these units specify a precise ozone concentration at a particular setting (EG Quantum 3 and similar devices) from the setting matrix the company publicises.
ANY device from a manufacturer that is supplied and functions by producing a precise ozone concentrations at a particular setting like the Quantum 3 from a matrix must be periodically calibrated.”
Updated view of Salvagente:
We are pleased that specific makes and models came forth as to eliminate any confusion caused by reference to “ozone machines”. We hope our clients and readers are put at ease that if they own an ozone sauna (purchased from Salvagente or elsewhere) they are not liable to “calibrate” their ozone generators.
We do urge people to be vigilant to the fact that even though some suppliers of ozone saunas also sell some of the products listed as “medical ozone devices”, it is different from their saunas and does not classify their ozone pod as a medical device under current legislation.
Because Salvagente does not directly engage in the distribution of the devices specified, we cannot speculate on the accuracy of the claims. However we remain skeptical about possible calibration of ozone generators based on the evidence that measuring the ozone output requires very specialized and expensive equipment.
We implore our clients and readers to seek answers whenever in doubt.
