One of the most productive cranberry farms in North America required an industrial process refrigeration system to freeze freshly harvested cranberries before distribution. Canneberges Bécancour sought a natural refrigeration solution that offered reliability, energy efficiency, and environmental sustainability.
M&M Carnot designed and installed a CO2 refrigeration system that operates in subcritical mode on most cooling days and in the supercritical mode only when necessary. The design mimics a rack system used in supermarket refrigeration and was factory-built and delivered to the site as a freestanding, self-contained system. For Canneberges Bécancour’s cranberry-freezing facility, three rack systems were developed. Each rack contains 13 reciprocating compressors and includes both high- and low-side components.
