The
Challenge: To
design and construct a new Ammonia based refrigeration plant to reduce energy
consumption.  The winery with a capacity
of 10,000 tonnes, consisted of a 400kW and 1000kW air cooled chillers on Freon
refrigerant.

The
Outcome:  Since constructing the plant, significant
power savings have been realised. The total power savings for the refrigeration
plant was more than 39% and demonstrated the benefits of highly efficient
Ammonia refrigeration. The new plant is capable of reducing the kWh per tonne
of crush average from 141 down to just 86.

 “A
total of 310,000kWh was saved on a like for like vintage, which translated to a
saving of more than $65,000, and that was just over the vintage period” -Paul
Dunnewyk.
