Or­ganic food firm uses ‘green’ re­frig­er­a­tion sys­tem

DEMM Engineering & Manufacturing - - FOOD PROCESSING -

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.”
