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.
“It’s true, we’ve seen a significant uptake for NH3/CO2 systems,” Hirsch said. “Four years ago only US Cold Storage was using the systems as well as the ice cream manufacturers like Nestle.”
“While ammonia systems are inherently safe to operate, it is an advantage to be able to lower the charge on site.”
“We now have a number of industrial refrigeration companies that are doing the design/builds, like Republic Refrigeration, which are able to interchange three or four equipment manufacturers. And now that we have competition in the market, the costs have come down.”
