The OXW-2k Ozone Generator will produce ozone efficiently from either Dry-Air or Oxygen feed-gas from a water-cooled ozone generation cell.  The OXW-2k is compact, efficient, and easy to use with a wide variety of options and features.

OXW Technology:

The OXW Ozone Generator series uses a Stainless Steel, water-cooled cell powered by solid state electronics and an oil filled transformer. Reliability of the ozone generator is excellent with a wide variety of operating parameters allowable. A robust control and automation system is incorporated to maintain a safe operating environment for both personnel and equipment, allowing for further reliability of the ozone generator. In addition, the corona cell is completely rebuildable and field serviceable

The OXW-2k Ozone Generator includes an automated control system to provide safe and reliable control of ozone generator.  Primary control of the ozone generator functions and display of status is indicated on a touchscreen display panel. This control system can also provide control for safe operation of the upstream oxygen concentrator, and closed loop water chiller used to cool the ozone generator cells.

An integrated ozone leak sensor is used to ensure human safety near the ozone generator.  In an event of an ozone leak in or near the ozone generator the OXW-2k ozone generator will turn OFF ozone production and set an ozone leak alarm.  

System Features:

• Water Cooled Ozone Generator for reliable ozone production
• Built-in ozone leak sensor for human safety
• Integrated oxygen purity meter to measure oxygen purity real-time
• Visual feed-gas flowmeter with flow adjust knob
• Visual feed-gas pressure gauge with pressure regulator

Ozone Generator Options:

Optional features are available to customize the OXW Ozone Generator to your specific application and needs.  Additional options and/or customization may be available, contact our office with any specific application questions.

Oxygen Purity Meter- Measure oxygen purity real-time with an inline ultrasonic oxygen purity meter.  Alarms can be set to alert of low oxygen purity.

Digital Feed-gas Flowmeter - Measure gas flow through the ozone generator real-time with a built-in mass flow meter providing accurate gas flow readings compensated for pressure and displayed on the ozone generator control interface.

Ozone Analyzer - Measure ozone concentration and ozone production real-time with the built-in ozone analyzer.  Measures ozone concentration via a UV absorption UV analyzer and displays this data on the ozone generator control interface.  When used with the digital feed-gas flowmeter actual ozone production in g/hr can be calculated and displayed.

Adjustable Ozone Output- control output of ozone generator from 0-100% is standard, this can be done with 4-20 mA or 0-10 VDC input.

Stainless Steel Enclosure - Standard enclosure is painted steel.  A stainless steel enclosure in either 304 or 316 SS is optional

Ozone Production:

- 2,580 g/hr from 490 LPM O2 @ 6% by weight

- 2,180 g/hr from 320 LPM O2 @ 8% by weight

- 1,740 g/hr from 200 LPM O2 @ 10% by weight

Using the OXW-2k Ozone Generator:

OXW-Series Ozone Generator Installed with the OXO Oxygen Concentrator, and Closed loop water chiller.  

Ozone output

The OXW-2k ozone generator is an efficient ozone generator that can produce ozone at very high ozone concentrations.  Review the ozone generator performance chart for details on ozone concentration, ozone production and required feed-gas.  A wide variety of ozone concentrations and/or ozone productions are possible based on feed-gas type or flow-rate. 

Feed-Gas Pressure

The OXW-2k ozone generator will produce ozone most efficiently at 20 PSI of pressure.  All performance data is listed at 20 PSI of pressure.  The OXW-2k will operate at pressures ranging from 10 - 30 PSI.

Feed-gas can be delivered to the OXW-2k at pressures up to 100 PSI safely.  All feed-gas pressure regulation and flow-control is built into the ozone generator to safely regulate pressure and flow for the ozone generation cell.

Automated Operation

Automated operation is a key feature of the OXW-2k Ozone Generator.  The following safety features and sensors are built into the ozone generator to allow for complete automation:

- Ozone leak sensor - shuts down ozone production at ozone levels from 0.1 - 1.0 ppm (user settable)

- Feed-gas Pressure Sensor - Closes inlet gas valve when feed-gas is below/above set-point

- Regulated Ozone Pressure Sensor - Shuts down ozone if pressure is below set-point.  Closes outlet valve is pressure is below low-low set-point to protect ozone generator cell from potential flooding

- Ambient temperature sensor - shuts down ozone generator if ambient temperature is above set-point

- Cooling water temperature sensor - shuts down ozone generator if cooling water, or cell temperature is above set-point.

Further automation is available to control an external air compressor, oxygen concentrator, water chiller, and ozone injection pump.  

Cooling Water

The OXW-2k Ozone Generator is water-cooled and requires cooling water for operation.  An external, closed-loop water chiller can be used to provide cooling water and allow for simple, automated operation.  Size the water chiller for the heat-load of the ozone generator and the potential heat-load of the ambient conditions.

Cooling water may be available from an on-site source.  Cooling water should be 70-deg F or cooler.  Cooling water flow-rate of 0.5 GPM is required for operation.  Cooling water should be clean, mineral free, and as pure as possible to prevent fouling of the corona cells.  

Typical OXW-2k Ozone Generator Installation:

The diagram below illustrates the typical installation of the OXW-2k ozone generator.  This shows the following equipment

• Rotary screw air compressor with integrated air dryer, air filtration, and air receiver tank to provide compressed air for the OXO-200 oxygen concentrator
• Oxygen Concentrator to provide 90%+ oxygen purity for ozone production
• Oxygen receiver tank to buffer oxygen flow and provide a consistent oxygen flow to the ozone generator
• Closed-loop cooling water to provide cooling of the ozone generator

Air Compressor System

• Packaged rotary screw air compressor with built-in refrigerant air dryer and air receiver tank.
• The air compressor is commonly provided as a packaged unit that self contained and controlled.
• Compressed air can also be provided by the facility. If on-site compressed air is available that is preferrable as it eliminates a new maintenance item long-term and lowers operating cost.
• This quote provides along with specifications for a compressor that could be used with the OXW-2k ozone generator.

Oxygen Concentrator

• Uses compressed air and PSA technology to remove nitrogen from the air and capture oxygen for ozone production.
• This can be controlled directly from the oxygen concentrator if desired.
• This quote provides along with specifications for an oxygen concentrator that could be used with the OXW-2k ozone generator.

Oxygen Storage Tank

• A necessary component of the oxygen concentrator to buffer oxygen production and flow to allow for consistant oxygen flow from the oxygen concentrator.
• This is listed with the oxygen concentrator as an option within this quote.

Closed Loop Water Chiller

• Provides cooling for the water cooled ozone generator.
• This allows efficient cooling of the ozone generator without the need for an external water source.
• On-site cooling water could be provided to the ozone generator if applicable. This would eliminate the need for the water chiller. 
• This quotes provides along with specifications for an oxygen concentrator that could be used with the OXW-2k ozone generator.
