Sprouts Farmers Market opened a store in July in Dunwoody, GA, with the first CO2-based, HFC-free supermarket refrigeration system in a warm weather market in North America.
The store runs on an Advansor transcritical booster system that eliminates hydro-fluorocarbons. Retailers and engineers in North America have questioned whether a CO2transcritical system — described as the cleanest and most environmentally friendly HFC-free option for commercial refrigeration — could be operated efficiently in areas where the ambient temperature climbs above 85F. Energy efficient, economical transcritical CO2refrigeration systems are normally limited to colder climates due to the limitations of air-cooled gas coolers. The key to Sprouts’ new system is a proprietary Trillium Series hybrid evaporative condenser by Baltimore Air Coil.
