Keeping it cool

As the Singapore training pool was too warm for our Olympic swimmers, Davey Water Products' Cool Pool solution is declared by Swimming Australia to be 'an outstanding success'.

The Australian swimming team headed for the London Olympics in July-August has been undertaking preparatory training in Singapore. However, Swimming Australia's initial investigation of the training pool facilities available indicated that the ambient pool water temperature in the humid local conditions would not be ideal.

Consequently, Swimming Australia investigated options that would potentially reduce the ambient water temperature by up to 3°C as well as create a more swimmer-friendly water condition.

Swimming Australia approached Davey Water Products to investigate what pool equipment options could be available to refresh the water conditions and reduce the ambient water temperature, including by aeration. This led Davey to produce two innovative Cool Pool pump systems, which are in use in Singapore after completing a testing program at Davey's headquarters in Melbourne.

The pumps have been declared "an outstanding success" by Swimming Australia's national head coach, Leigh Nugent. "We have been running them for about 18 hours a day and they have been effective at keeping the water temperature to 28.5°C," he says. "Without them, our swimmers would be in water of 31°C - effectively too hot to train in. Davey has supported the Australian swimming team significantly in its preparations for the London Olympics."

Created as two self-contained packages, the Cool Pool units each employ a Davey Power Master 450 electric pool pump, which recovers the pool water at a rate of 450 litres per minute and then distributes it across the pool surface through two Davey fire-fighting nozzles. The water drawn out of the pool is recirculated as a fine mist through the air, cooling through evaporation, before being delivered back into the pool.

"The trajectory and water-surface coverage obtained by the nozzles is also adjustable according to the size of the pool," Davey's Production Co-ordinator, Robert Hodder, says.

Each of the two Cool Pool units is fabricated as a self-contained unit mounted on a 304 stainless-steel base to give an easy means of lifting and handling.

In addition, when the unit is operating a waterproof LED light strip is illuminated to show that the pump is ready for action.

Australian swimmer Geoff Huegill with one of the two Davey Cool Pool pumping units developed to enhance the condition of the water in the training pool in Singapore that was used for Swimming Australia's London Olympic Games trials. Unfortunately, Geoff didn't make the Olympic team.

Described as "an outstanding success" by Swimming Australia, the Davey Cool Pool units reduce the water temperature in the pool by 2.5-3°C to give perfect water conditions for training.
