WHY OHEN GROUP'S OZONE GENERATORS?
Features of the Ohen 4.1
-
Low flow rates. This has a dramatic increase in the effect of ozone due to increased concentration leading to more oxidation. The oxygen thus also lasts longer than other ozone generators reducing the amount of refills needed if using an oxygen cylinder (one 3L cylinder lasts 3 months with regular use).
-
Ohen medical grade, inert materials sourced from Italy, Germany and accessories sourced in local markets (see our going green initiatives).
-
The only one of its kind that can be used for both home and professional medical use.
-
Pre-calibrated output creating an easy to use interface without a need to understand how to provide the correct concentrations of ozone. The Ohen unit only provides the highest concentration. Simply set a treatment time and turn the Ohen unit on.
-
The Ohen 4.1 is accurately calibrated to produce high-grade medical ozone from medical oxygen. People with medical training can use the Ohen 4.1 to administer ozone intravenously.
-
The Ohen unit can be serviced and repaired and replacement accessories are available to purchase.
-
Extremely safe to administer with or without knowledge of ozone.
The Ohen unit complies with all the major requirements of medical ozone generators which includes:
-
The oxygen source must be high purity oxygen and NOT ambient air. Ambient air contains less than 20% oxygen and many chemical toxins.
-
The output of the machine should be measured and calibrated in micrograms of ozone per milliliter of oxygen (µg/mL) and not the industrial standard of milligrams per hour (mg/h)
-
The machine should be issued with a calibration certificate confirming that the concentration of ozone produced is viable for human use. Concentrations too weak will have no beneficial impact and concentrations too strong are harmful especially to lung tissue.
-
Medical ozone machines must comply with safety regulations.
-
The material used in manufacturing medical ozone machines must be of medical grade to produce high quality medical ozone (often other ozone machine manufacturers use industrial standard material). The materials must also be ozone inert; many materials such as plastic and untreated silicon will perish quickly when exposed to medical grade ozone.
Units are registered to the paying customer who will receive the value added services. Reselling of Ohen units is prohibited however, to transfer ownership to someone else, please contact us for assistance. High-value trade-ins are also available should you no longer want your Ohen unit.
Our Ohen units are carefully manufactured and calibrated in line with international standards and compliance. At Ohen Group, we take this very seriously due to the nature and uses for our products.
