The OEM is offering both transcritical CO2 and low-charge packaged ammonia.
Units include improved EEV and controls for racks and cases that make CO2 more affordable, says company.
The installations of the air-cooled units took place over the summer at mostly new stores operated by a handful of U.S. chains.
The cold-storage operator’s second transcritical system will replace R404A equipment.
New Jersey store also features energy-saving features like demand response and enclosed refrigeration cases.
The 170-TR chiller will service an existing ice rink as well as a new rink.
