Core Technology & Data

High-Concentration Ozone Generation

At the heart of the H-Series is advanced corona discharge technology, where high-voltage electrical energy is applied across a dielectric medium to convert oxygen molecules (O₂) into ozone (O₃). For high concentration generation, Eltech’s units typically use high-purity oxygen feed gas, which significantly boosts ozone yield per unit of feed gas when compared to ambient air-fed systems.

Feed Gas & System Configuration

• • Oxygen Feed: Using concentrated oxygen (from PSA oxygen concentrators or bottled oxygen) enables the generation of higher ozone concentrations (typically much greater than air-fed units), offering stronger oxidative potential and improved solubility in treated media.
• • Drying & Filtration: Feed gas is dried and filtered to ensure consistent corona discharge performance and minimal by-product formation. Moisture and impurities in feed gas decrease ozone output and shorten electrode life, so conditioning is critical to system stability and longevity.

Controls & Safety

H-Series generators feature an integrated control interface:

• • Output adjustment for precision dosing
• • Interlocks and safety shutdowns for over-current, over-temperature, and feed gas anomalies
• • Monitoring instrumentation for ozone output, feed gas flow, and system health

The combination of high-purity feed gas, optimized corona cell design, and precision control results in consistent, high-density ozone delivery across industrial duty cycles.

Benefits & Performance Highlights

1. 1. High Ozone Concentration Output
   H-Series units generate elevated ozone levels that support deep oxidation and superior disinfection, making them ideal for applications requiring rapid microbial inactivation or strong oxidative breakdown.
2. 2. Enhanced Oxidation Efficiency
   The use of high-purity oxygen increases ozone production efficiency and improves ozone transfer into water and air streams, enhancing treatment performance per unit of power.
3. 3. Industrial-Grade Reliability
   Built for continuous operation in demanding environments, the H-Series features durable components and design optimizations that reduce downtime and extend service life.
4. 4. Versatile Application Suitability
   Whether deployed for potable water treatment, wastewater polishing, cooling tower hygiene, HVAC air quality enhancement, or process oxidation in manufacturing, the H-Series adapts to a broad assortment of industrial needs.
5. 5. Clean & Controlled Output
   Higher feed gas purity limits undesirable by-products (like nitrogen oxides) and yields ozone that is more efficient for target reactions without introducing excessive secondary contaminants.
6. 6. Precision Control & Safety
   

   Integrated control systems provide operators with the ability to adjust ozone output according to specific process requirements while safeguarding system health with automatic protective features.

7. 7. Eco-Friendly & Residue-Free Operation
   

   Ozone naturally decomposes into oxygen after reacting with contaminants, leaving no harmful residual chemicals behind — a key advantage for sustainable water and air treatment strategies.

8. 8. Lower Operational & Lifecycle Costs
   

   While oxygen-fed systems involve an upfront investment in oxygen supply infrastructure, the higher ozone yield and improved treatment performance often translate into lower energy use and reduced chemical costs over the equipment lifecycle.
