NEXT Series: CO2 needs a little help from its friend – ammonia
Manufacturers and end users in Europe and North America are confident that CO2 will grow in combination with ammonia in industrial applications.
In this latest of our NEXT Series of articles, CO2 system manufacturers and component suppliers – along with end users – expressed confidence to this website that CO2 would increase in industrial applications, mainly with help from another natural refrigerant – ammonia. “We see an increased interest in the [industrial] market in general,” Brandon J. France, director of packaged refrigeration systems at Stellar, a U.S. contractor, told R744.com. “The acceptance of CO2 will increase as people become more comfortable with the technology.” European system manufacturer Tecnofreddo argues that CO2 industrial systems are becoming more popular for many reasons. “New technological developments in components have allowed CO2 transcritical systems to reach greater capacities,” said Manuela Rallo, sales area manager at Tecnofreddo. Falling system prices and improved safety are also making CO2 an attractive option for the industrial refrigeration market, Rallo argued. “For all these reasons, Tecnofreddo has decided to [develop] a new series of transcritical units [for industrial applications],” Rallo said. CO2-ammonia: A good combination Despite the growing popularity of CO2 for industrial applications, many end users still prefer to combine it with ammonia. Campbell Soup is a case in point. It will “phase out our R22 equipment and utilise either CO2 or ammonia/glycol systems,” according to Bing Cheng, senior manager (utilities, environmental and sustainability programs) at Campbell Soup.
