A high-level panel discussion on securing the supply of refrigerant-grade CO2 (R744) for the growing number of transcritical CO2 refrigeration installations in North America is planned for June 12 at the ATMOsphere (ATMO) America Summit 2023 on natural refrigerant-based HVAC&R.

This 12th annual edition of the conference will be held Monday, June 12, and Tuesday, June 13, 2023, at the Mayflower hotel in Washington, D.C.. The event, addressing applications of the natural refrigerants CO2, hydrocarbons and ammonia, is organized by ATMOsphere, publisher of R744.com.

Panelists in the CO2 supply session include James McClendon, Director of Energy Efficiency, Walmart Stores; Scott Ercole, Vice President of Technical Sales, Coolsys; and Derek Gosselin, Director of Technical Product Support, Dover Food Retail/Hillphoenix. The session will be moderated by Danielle Wright, Executive Director, North American Sustainable Refrigeration Council (NASRC), which is co-hosting the session with ATMOsphere.

This panel discussion will examine challenges and strategies associated with securing the supply of CO2 refrigerant, including purity-level requirements and minimizing leak rates.

Along with this panel, a wide range of CO2 (R744)-related case studies will be presented at ATMO America. In addition, the conference will feature several refrigeration and heat pump presentations involving the use of ammonia (R717), as well as presentations on hydrocarbon refrigeration and charge-limit standards.

You can register for the event here and find the program and other information on the event website.  End users can register for free, and contractors/installers of HVAC&R systems are eligible to receive one free ticket per organization, with a 50% discount on additional tickets.

Many end user and contractor speakers

A large number of end users and contractors – including Walmart, Ahold Delhaize USA, Lineage Logistics and CoolSys – will be speaking on their experiences with natural refrigerant-based systems.

There will be two policy-related sessions, one on technology transitions with the EPA and one on per- and polyfluoroalkyl substances (PFAS).

Other speakers confirmed for the event include:

  • Rob Bradley, Managing Director, Climate Change and Sustainability Services, Ernst & Young
  • Ben Churchill Chief Strategy Officer, CoolPlanet

ATMO Awards will be presented to a retailer and an industrial end user, and attendees will vote on three products to receive the Innovation of the Year award. A Person of the Year will also be named.
