In November’s special training edition of Accelerate America, AAA Refrigeration Service talked about stepping up its training programme to encompass CO2 technology to meet the needs of supermarkets installing transcritical and cascade refrigeration systems.
Les Atokas Bieler, in collaboration with Carnot Refrigeration, opted for a CO2 transcritical technology to chill cranberries at its new refrigeration warehouse in Quebec, Canada.
A new paradigm in industrial refrigeration is emerging in the United States with ammonia-CO2 systems helping alleviate safety concerns while catering for large-scale refrigeration capacities. Accelerate America investigated the trend in the magazine’s October edition.
