When purity, performance, and long-term reliability are top priorities, the RMU-DG4 Ozone Generator delivers unmatched results. Built with Double Quartz Dielectric Technology and no metal in the gas path, this ozone generator is specifically engineered to produce pure, uncontaminated ozone while ensuring maximum longevity—even under demanding conditions.
Pure Ozone. No Contaminants. No Compromises.
The RMU-DG4 produces up to 40 grams per hour of ozone from only 6 liters per minute (LPM) of oxygen using a highly durable corona discharge cell. Unlike traditional ozone generators, the RMU-DG4 features an all-quartz internal gas path—no stainless steel or metal ever contacts the oxygen or ozone. This design eliminates any risk of chemical contamination or corrosion caused by poor-quality feed gas.
This makes the RMU-DG4 an ideal solution for applications requiring the highest ozone purity and long-term durability, such as:
- Water bottling facilities
- Self-contained environmental remediation systems
- Commercial air purification and treatment systems
Key Features of the RMU-DG4
- Produces up to 40 g/hr of ozone from oxygen efficiently
- Double Quartz Technology for ultra-pure ozone
- Designed for rack mount or benchtop use
- Integrated flow meter with control valve
- Adjustable ozone output
- Pressure switch for added safety
- Detachable power cord for easy installation
- Durable powder-coated aluminum enclosure
- Compatible with modular 19″ rack systems for scalable design
Modular and Scalable Design
The RMU-DG series is built for flexibility. The standard 19” rack-mountable design allows multiple generators to be installed side-by-side, enabling future expansion without costly retrofitting. Alternatively, the unit can be operated as a standalone benchtop system, making it suitable for labs and compact installations.
Performance Specifications – Ozone Output from Oxygen
| O₂ Flow Rate | Ozone Output | Concentration |
|---|---|---|
| 2.3 LPM | 20 g/hr | 10% (150 g/m³) |
| 4 LPM | 30 g/hr | 8.5% (120 g/m³) |
| 8 LPM | 40 g/hr | 5.7% (82 g/m³) |
| 15 LPM | 50 g/hr | 3.9% (55 g/m³) |
This performance ensures that even at high outputs, the RMU-DG4 maintains a strong ozone concentration, ideal for efficient dissolution into water or air treatment systems.
Recommended Oxygen Source: OG-20
For optimal performance, we recommend pairing the RMU-DG4 with the OG-20 Oxygen Concentrator, which provides 10 LPM of high-purity oxygen. This ensures you get maximum output without compromising efficiency or safety. If you’re considering an alternate oxygen source, our technical team is happy to help you confirm compatibility.
Inside the Double Quartz Corona Cell
At the heart of the RMU-DG4 is its advanced Double Quartz Corona Cell, a design that sets this unit apart from traditional ozone generators:
- True quartz construction (not glass) for strength, rigidity, and ozone resistance
- No internal metal contact — oxygen and ozone only touch quartz and Teflon
- External and internal cooling via aluminum heat sinks and hollow tube airflow
- Leak-proof construction for enhanced safety and reliability
This design allows for cooler operation, which improves ozone generation efficiency while dramatically extending the lifespan of the corona cell.
Unmatched Purity. Proven Reliability.
Whether you’re looking to maintain high water quality standards, perform sensitive environmental remediation, or purify air in demanding commercial environments, the RMU-DG4 Ozone Generator offers the purest ozone available with industry-leading dependability.
