U.S. OEM Hussmann, a division of Panasonic, announced that it has recently added production capacity for its outdoor transcritical CO2 (R744) rack systems for retailers in its Suwanee, Georgia, facility.

“The rapid adoption of CO2 technology by many retailers has placed a strain on the current original equipment manufacturer (OEM) capabilities and Hussmann is responding to meet the challenge,” said Hussmann in its announcement.

Hussmann attributed the accelerating demand for transcritical CO2 systems to retailers’ Environmental, Social and Governance (ESG) initiatives, upcoming regulations and HFC phase downs. In particular it cited the anticipated January 2025 implementation of U.S. Environmental Protection Agency (EPA) regulations on new store construction.

The expansion of its production capabilities are focused on Hussmann’s large outdoor transcritical rack platform, part of the Evolve Technologies portfolio, which is designed to serve large and medium-sized retail stores. This unit’s footprint is optimized to consider loading limitations in areas where snow is common and flexible enough to accommodate various internal configurations, Hussmann said. It is Underwriters Laboratories (UL) listed and 50-state compliant.

Transcritical CO2 rack systems are ideally suited for new construction projects where there is no existing refrigeration infrastructure, Hussmann said, adding that refrigerated display cases, unit coolers and piping from existing synthetic systems are not suitable for use in a CO2 application.
