Transcritical CO2 (R744) refrigeration “seems to be the way of the future for us,” said Doug Milu, Manager, Refrigeration & Energy Program for Publix Super Markets, a Lakeland, Florida (U.S.)-based food retailer that operates 1,284 stores in seven Southeastern states,
Milu imparted that message during the end users session at the ATMOsphere America conference, held online on November 3. ATMOsphere America was organized by ATMOsphere (formerly shecco), publisher of R744.com.
Publix has so far installed transcritical CO2 systems at a store in Longwood, Florida, which opened in June 2020, and a store in Tampa, Florida, which opened in August 2021. A third store opening on November 17 in Chattanooga, Tennessee, will also employ a transcritical CO2 system.
