install a new refrigeration plant, as a key component of a major upgrade of the
winery’s energy systems . Cold Logic had been approached by Wirra Wirra,
after the winery’s energy prices had doubled between 2008 and 2013. Cold Logic
installed a new high efficiency ammonia refrigeration plant to cater for a
planned 2500 tonne grape crush.
The Outcome: Wirra Wirra’s CEO, Mr Andrew Kay, said the energy and maintenance savings from the new refrigeration plant alone was worth nearly $25,000 a year. “The new high efficient ammonia refrigeration plant, together with upgraded brine lines and solar panels, had delivered savings of nearly 50% from Wirra Wirra’s annual energy bill,”.
