Huon Aquaculture installs innovative chilling technology

Huon Aquaculture Group, a salmon farming operation based in Tasmania, Australia, has installed a specialized, large-capacity chiller at one of its key hatcheries.

Huon hired Fresh By Design and sub-contractor Rheem Australia for its technical expertise in designing the chiller, which encompassed a total volume of 330,000 liters, spread between a dozen 22,000-liter tanks and including 260 square meters of exposed water area.

“The project brief called for us to be able to vary the water temperatures in the tanks from seven to 14 degrees Celsius month-by-month depending on where the fish were in their growth cycle,” Rheem Pool Heating’s national sales and marketing manager Mark Crowther said in a press release.

Rheem’s solution was to install two Accent 50 kilowatt chillers that now help to control temperatures in waters that support 9,000 kg of fish.

Huon, which produces between 15,000 and 30,000 metric tons of Atlantic salmon primarily for domestic consumption in Australia, uses a full recirculation system that reuses 95 to 99 percent of its water. The water it must exchange is used for composting, land-spreading and irrigation, it said in the release.
