New Option:

The VMUS-DG1 is a wall-mount ozone generator designed to produce ozone efficiently from oxygen.  This air-cooled ozone generator uses a double quartz corona cell to produce ozone.  This unique corona cell provides pure ozone production from oxygen, with the best reliability of any air-cooled ozone generator on the market.  Produce 12 g/hr of ozone efficiently from less than 4 LPM of oxygen.  The VMUS-DG1 operates at oxygen pressures up to 10 PSI, providing flexibility in your ozone application.

This ozone generator conforms to CSA C22-2 No. 61010-1 and UL 61010-1.

Integrated Flow switch:

The VMUS-DG uses an integrated flow switch for simple and reliable automation. This switch will turn the ozone generator ON when feed-gas flow rises above about 1.5 LPM, and turn the ozone generator OFF when feed-gas flow drops below about 1 LPM. This provides some simple automation for your ozone system. When used with a simple venturi injector the VMUS-DG will turn ON and OFF automatically based on suction from the venturi. When used with an oxygen generator the VMUS-DG1 will turn ON and OFF automatically when flow starts or stops from the oxygen generator. This feature eliminates the need for external wiring or flow/pressure switches.

When the ozone generator is turned OFF due to no flow, the No Flow light illuminates indicating this. When flow is present this No Flow light will go out, and the blue Ozone light will illuminate, indicating ozone is now produced.

Adjustable Ozone Output:

The VMUS-DG uses a digital adjustable ozone output shown in image above. This will allow setting the ozone output from 0-100% using the rocker switch. Green status lights will show the current power setting of the ozone generator clearly and easily. The ozone output can also be adjusted while the ozone generator is in a No Flow status and not producing ozone.

Circuit Protection:

The VMUS-DG uses a sophisticated power inverter board that will protect the corona cell and/or transformer against failure. In the event the corona cell does become contaminated with moisture, or dust the inverter will turn OFF ozone production immediately to protect against damage. Every 6 seconds this inverter will attempt to produce ozone and will restart automatically when conditions improve. While we hope our customers never flood, or contaminated the ozone generator corona cell, we know this is a possibility, this circuit protection will prevent potentially costly repairs.

Using the VMUS-DG1 with Venturi to dissolve ozone into water:

We provide a variety of oxygen concentrators that could be used with the VMUS-DG1.  Our recommendation would be the MAX-5 Oxygen Concentrator.  The MAX-5 will produce 5 LPM of oxygen at pressures up to 10 PSI.  This is sufficient for over 12 g/hr of ozone production from the VMUS-DG1.  The oxygen pressures, flows and general operation of the MAX-5 will be a great fit with the VMUS-DG1.  However, if you choose to use your own oxygen concentrator, simply contact our office and let us ensure it is the right fit for your application.

The drawing below illustrates a simple system to dissolve ozone gas into water with a venturi injector.

Ozone generated from oxygen will be generated at a high concentration, and will therefore dissolve into water more efficiently.  Therefore, if using ozone to be dissolved into water consider using an oxygen concentrator first.

Using the VMUS-DG1 with diffuser to dissolve ozone into water:

The diagram below illustrates setting up the VMUS-DG1 with an oxygen concentrator to bubble ozone gas into water.

The VMUS-DG1 will operate at oxygen pressures up to 10 PSI, sufficient pressure to push gas through a diffuser and into a tank.  As the VMUS-DG1 produces ozone at a high concentration, ozone solubility into water will be excellent.  Using the MAX-5 oxygen concentrator with the VMUS-DG1 will allow for sufficient oxygen flow and pressure to produce over 12 g/hr of ozone and delivery ozone and oxygen at pressures up to 10 PSI.

Using the oxygen concentrator allows the VMUS-DG1 to produce ozone under pressure for a variety of applications.  The drawing below shows ozone bubbling into a tank to dissolve ozone into water.  However, using an oxygen concentrator and the VMUS-DG1 ozone generator ozone can be produced for a wide variety of ozone applications.

Double Quartz Corona Cell:

The DG-Series ozone generator uses double quartz corona cell technology.  The corona cell used in the DG-Series is made of true quartz.  See image below for example.  The oxygen gas is plumbed inside the ozone generator via Teflon tubing.  This oxygen will pass into the quartz corona cell and touch only quartz materials.  The stainless steel electrode and cathode are placed on the outside and inside the quartz tube.  The oxygen/ozone gas never touch any metal materials.

This double quartz design will completely eliminate leaks in the corona cell.  This also dramatically increase the reliability of the corona cell.  As the corona cell dielectric and construction are true quartz, not glass, they are rigid and strong, yet also completely impervious to ozone. 

The VMUS-DG1 uses one of the cells shown in image above.  The VMUS-DG3 uses three of these cells.  Each are air cooled and plumbed in series.

The Quartz dielectric uses aluminum cooling fins enclosing (and protecting) the quartz dielectric.  This corona cell is air cooled via fans from the outside of the cell, but is also cooled through the hollow tube inside the quartz dielectric.   This allows the corona cell to be cooled both internally and externally.  Better cooling reduces heat and allows ozone to be produced more efficiently.

The DG series of ozone generators will produce the purest possible ozone, yet offer the best reliability in any corona cell design.
