How Lex Aqua works

One continuouswater loop.

The cycle starts after the resurfacer leaves the ice. Snow enters the melting pit, the recovered water is purified through filtration and UV treatment, then reheated and returned for reuse.

Water cycle From snow to reuse

Active

Capture Resurfacer snow enters the melting pit.

Filter Recovered water moves through filtration.

UV treatment UV treatment supports the purification stage.

Reheat Cleaned water is brought back to operating temperature.

Return Prepared water returns to the resurfacer for reuse.

Cycle structure Recover → Treat → Return

Freeze cycle Mineralsseparate Treatment keeps them from cycling back

Why treatment matters

The loop returns cleaner water.

As water freezes, minerals separate from the forming ice crystals. Lex Aqua is designed to keep those minerals and other pollutants from simply re-entering the next ice-making cycle.

Reduce recirculated impurities Support cleaner water entering the ice Maintain a controlled recovery cycle

Follow the water

From the pit to the next flood.

The system sits behind daily rink operations, recovering a resource that would otherwise be treated as waste.

Capture

The resurfacer delivers the source water.

After resurfacing, the ice machine releases collected snow into the melting pit. As that snow melts, the resulting water becomes the source for the Lex Aqua recovery cycle.

Purify

Filters and UV treatment clean the recovered water.

Water from the pit moves into the treatment process. Filtration reduces unwanted material, while UV treatment forms another part of the purification sequence before reuse.

Prepare and reuse

Cleaned water is reheated and returned.

Once the treatment sequence is complete, the water is reheated and returned to the ice machine. The next resurfacing cycle can begin with recovered water prepared for reuse.

Output Water ready for another cycle

Operation and control

The process runs automatically. Operators stay informed.

Lex Aqua is designed for automatic operation, while retaining manual control when rink staff need it. A responsive touchscreen provides local visibility, and the system can also be monitored and managed remotely.

Capture → Treat → Return

The closed-loop result

A better input for the next sheet of ice.

The purpose of the process is not just to reuse water. It is to recover it through a controlled treatment sequence before it returns to ice production.

Less incoming water

Recovered water reduces the amount of new water required for ongoing rink operation.

Fewer impurities

Treatment reduces minerals and other pollutants before water returns to the cycle.

Better ice formation

Cleaner water supports the formation of ice crystals with fewer impurities.
