Primozone Ozone Generation Technology – High‑Performance, High‑Efficiency, Low‑Maintenance

Primozone’s ozone generation technology is built around its patented anodized aluminium reactor, an advanced evolution of the cold plasma (dielectric barrier discharge) method. This next‑generation design delivers exceptional ozone output, superior energy efficiency, and long operational life—making it one of the most effective ozone technologies available today.

Compact, High‑Efficiency Reactor Design

At the core of every Primozone generator is a compact anodized aluminium reactor engineered for maximum gas conversion efficiency. Unlike conventional glass‑tube reactors, the Primozone design shortens the oxygen travel path, enabling:

  • Higher ozone production efficiency

  • Lower energy consumption

  • Naturally higher gas output pressures

These higher pressures are key to achieving industry‑leading ozone concentrations and superior ozone dissolution in water, especially in demanding industrial and municipal applications.

Powerful Ozone, Perfectly Cooled

Primozone ozone generators feature fully integrated water‑cooled reactors and power units, ensuring optimal temperature control during operation. Stable cooling delivers:

  • Higher ozone output

  • Consistent performance

  • Longer component lifespan

  • Reliable operation in harsh environments

This makes Primozone systems ideal for continuous, high‑demand water treatment processes.

Modular Design for Maximum Flexibility

The Primozone GM‑Series is built on a modular architecture, allowing operators to scale ozone capacity precisely to their needs. Benefits include:

  • Flexible system sizing

  • Easy expansion as demand grows

  • Minimal footprint compared to traditional systems

  • Simple retrofitting into existing ozone rooms

  • Continuous operation—other modules stay online during service

This modularity ensures you never oversize your system and can expand capacity effortlessly as operations evolve.

A “No‑Need‑to‑Clean” Reactor Philosophy

Primozone reactors are engineered for minimal maintenance. Their robust aluminium construction and high internal gas pressure prevent contaminants from adhering to internal surfaces. The result:

  • Maximum uptime

  • Reduced service requirements

  • Long‑term operational reliability

  • Consistent ozone performance

This makes Primozone ideal for aquaculture, municipal water treatment, industrial oxidation, and any application requiring dependable, low‑maintenance ozone production.

High‑Concentration Ozone Technology – Maximum Output, Minimum Energy

Primozone ozone generators deliver the highest ozone concentrations on the market, producing up to 20 wt% ozone through an advanced cold‑plasma reactor design. This highly efficient method creates more free oxygen radicals, enabling superior ozone production while using significantly less oxygen and less energy than traditional systems.

Because Primozone technology maintains constant high concentration at all output levels, oxygen and energy consumption scale linearly with demand—dropping to as low as 10% during low‑load operation. This ensures exceptional efficiency and low operating costs year‑round.

Superior Ozone Dissolution & Mass Transfer

Primozone systems are engineered not only to produce high‑concentration ozone, but also to deliver it to the dissolution point with no losses. The combination of high concentration and three‑times‑higher gas pressure results in:

  • Up to 95% more dissolved ozone in water

  • Far more efficient mass transfer

  • Reduced oxygen content in the gas mixture

  • Smaller gas volumes and lower booster pump requirements

This means better treatment performance, lower energy use, and reduced capital cost for downstream equipment.

More Ozone, Less Oxygen – Proven Performance Advantage

Primozone technology provides:

  • 7× higher ozone production capacity at high concentrations compared to conventional systems

  • Half the oxygen consumption of traditional generators

  • Smaller gas volumes, reducing ozone destruction energy

  • Consistent high concentration, regardless of output level

High concentration + high pressure = the most efficient ozone dissolution available, enabling users to meet treatment capacity with dramatically lower operating costs.

  • No oversizing

  • No full‑capacity backup units

  • Lower capital investment

  • Smaller installation footprint

Easy Expansion & Simple Retrofits

Because Primozone modules are compact, they can be retrofitted into existing ozone rooms where traditional generators once stood. As treatment needs grow, operators simply add more modules, allowing the system to scale effortlessly without major redesigns or downtime.
