The Ozone XLM with pH control is an integrated system presented in a single enclosure,
minimising the space required for pool equipment and the need to install multiple components.
The Ozone XLM combines a powerful corona discharge ozonator with an extra-low mineral salt Centuries Old Tradition chlorinator, creating one of the most powerful and efficient sanitisation systems available.

The Ozone XLM harnesses the power of Ozone to deliver a highly effective mineral pool
sanitisation system.
The Ozone XLM is designed to work at extra low concentrations of mineral salt – reducing initial setup and ongoing maintenance costs.
Ozone XLM units integrate pH control for perfectly balanced water that is a pleasure to swim in.
Ozone XLM comes in a range of sanitiser output sizes – 12g/hr, 18g/hr, 23g/hr and 28g/hr to suit different applications.

How Corona Discharge Ozone Sanitises Pool Water

Ozone is a powerful and natural sanitiser, and when generated using corona discharge (CD) technology, it becomes a highly effective way to purify pool water without relying solely on chlorine or other chemicals.

✅ What Is Corona Discharge Ozone?

Corona discharge is a method of generating ozone (O₃) by passing oxygen (O₂) through a high-voltage electrical field. This electrical energy splits oxygen molecules into individual atoms, which then recombine with other oxygen molecules to form ozone.

O₂ + Energy → 2O
O + O₂ → O₃

CD ozone generators are popular because they:

Produce a higher concentration of ozone

Are more energy-efficient

Have a long lifespan with minimal maintenance

✅ How Ozone Sanitises Pool Water

Once introduced into the pool system (usually injected into the return line via a venturi or injector), ozone immediately begins to oxidise and destroy:

Bacteria

Viruses

Algae

Organic contaminants like body oils and lotions

Ozone is up to 3,000 times faster and 50 times more powerful than chlorine at killing certain pathogens. It works by breaking down cell walls and disrupting the DNA of microorganisms.

✅ Benefits of Corona Discharge Ozone for Pools

Chemical Reduction: Significantly lowers chlorine usage, reducing skin/eye irritation and chemical smell

Cleaner, Softer Water: Water feels silkier and looks clearer

No Residual Byproducts: Ozone breaks down into oxygen, leaving no harmful residues

Eco-Friendly: Reduces the number of chemicals entering the environment

⚠️ Important Notes

Ozone is a point-of-contact sanitizer, meaning it works in the ozone chamber or mixing zone, but doesn’t leave a lasting residual in the pool. A small amount of chlorine or other residual sanitiser is usually still required.

Proper installation and maintenance of the ozone system are essential for optimal effectiveness.
