Tube-Type Plasma Ozone Generators

Compact, Versatile & Ideal for Mid-Scale Operations

For applications where compact size, flexibility, and modular scalability are important, ORAIPL offers Tube-Type Plasma Ozone Generators.

These systems use ceramic or quartz dielectric tubes for the corona discharge, producing ozone concentrations suitable for commercial disinfection, agricultural irrigation, food storage, and small-to-medium industrial plants.

Technical Working of Tube-Type Plasma Ozone Generators

Tube-Type Plasma Ozone Generators by ORAIPL operate on the principle of Dielectric Barrier Discharge (DBD) inside cylindrical tubes. In this design, oxygen gas is exposed to a high-voltage alternating current field across a dielectric barrier, splitting O₂ molecules and recombining them as ozone (O₃).

Core Components

1. Dielectric Tube

   • Made of high-quality ceramic (for small models) or quartz glass (for large models).

   • The dielectric barrier prevents arcing, ensuring a stable plasma discharge.

   • High dielectric constant (ceramic) and thermal stability (quartz) improve service life and reliability.

2. Electrodes

   • Inner and outer electrodes create the corona discharge field.

   • Electrodes are precision-designed for even plasma distribution, which prevents hot spots and ensures uniform ozone output.

3. Oxygen Feed

   • Oxygen gas with purity ≥ 93% (from PSA oxygen generators or LOX tanks) is fed into the tube.

   • Flow rate determines the achievable ozone concentration (120–220 mg/L for large units).

4. Cooling System

   • Air-Cooled Models (5–50 g/h): Internal/external electrode cooling for portability and small-scale use.

   • Water-Cooled Models (≥100 g/h): High-efficiency cooling to maintain electrode surface temperature ≤ 30°C, preventing ozone degradation and ensuring long-term operation.

Step-by-Step Ozone Generation Process

1. Oxygen enters the dielectric tube under controlled pressure.

2. High-voltage plasma discharge (8–15 kHz) ionizes the oxygen molecules, splitting O₂ into atomic oxygen (O).

3. Recombination occurs, forming ozone (O₃) in concentrations up to 220 mg/L.

4. Continuous cooling of electrodes and dielectric prevents overheating, ensuring ozone remains stable and output does not attenuate over long operating hours.

5. The generated ozone exits the system and is directed into the process application (water, air, gas stream).

 Performance Characteristics

• Scalable Output: From 5 g/h (portable lab use) to 50,000 g/h (large industrial plants).

• Concentration Range: 65–120 mg/L (ceramic models) and 120–220 mg/L (quartz models) depending on flow.

• Energy Efficiency: Low power consumption per gram of ozone, thanks to high dielectric efficiency.

• Durability: Ceramic and quartz materials resist thermal stress and corrosion, ensuring long service life.

• Low Maintenance: Tubes are modular and can be replaced without dismantling the entire generator.

Advantages of Tube-Type Design

• Compact and lightweight → ideal for portable and modular setups.

• Flexible cooling (air or water) → adapts to small or industrial-scale systems.

• Stable ozone output without attenuation during continuous use.

• Energy savings through optimized plasma discharge and low power supply consumption.
