For refrigerated and frozen food processors, choosing between an ammonia or an ammonia/CO2 cascade system can be one of the most important variables.

Inex, a Belgium-based producer of dairy products, achieved minimum energy savings of at least 18% from its refrigeration process as a result of switching to Dyneo permanent magnet motor technology from Emerson Industrial Automation USA.

Target Corp. and Whole Foods Market keep grocery aisles warm by re-using the heat emitted by refrigeration systems as a natural by-product, thereby saving additional energy during cold months.
