Energy audit and refrigeration upgrade - Radevski Coolstores

Radevski Coolstores in the Goulburn Valley Victoria is a major supplier of apples and pears to Coles. It undertook a $1.15 million upgrade of 2 cool store systems, to allow the plant to operate on ammonia as a refrigerant, and to use condenser fan speed control (using variable speed drives) to further improve performance. The results were significant: one site recorded 60% reduction in its maximum electrical demand, and the upgrades will cut the company’s energy costs by 25%.
