Organic food firm uses ‘green’ refrigeration system
Kiwi businesses EcoChill and food firm Ceres Enterprises have joined up to create what they claim is the first ‘greenrated’ cold storage facility in the country.
EcoChill uses natural gases such as carbon dioxide (CO2), propane and water as coolants in its machines.
“When first researching refrigeration solutions for our organic produce, we came across EcoChill and it felt such a natural fit,” says David King, director at Ceres Enterprises.
“Our brief was to create a cool room with a volume of over 2550m3, capable of operating down to 20C.”
EcoChill created a system that uses 80 per cent less refrigerants with no electrical defrost requirements whatsoever.
Matthew Darby, owner of EcoChill, says: “A system of this size requires a significant quantity (30+ kg) of synthetic greenhouse gases, posing massive global warming potential, and significantly more electrical input (for defrosting).
“When you take some of that global warming potential away by using refrigerants inside, and make it use less power to do that, you’ve got a twofold benefit to the end user.”
