G&D Chillers said A2L refrigerants are now the standard across its glycol chiller platform. The Oregon-based company said all new systems, excluding low-temperature applications, will be built with A2L-rated refrigerants to align with evolving regulatory requirements and updated safety standards across North America.
The company said the change comes as federal regulations, updated safety standards, and building code changes reshape refrigeration system design, installation, and approval. It cited the U.S. Environmental Protection Agency’s American Innovation and Manufacturing (AIM) Act, which is phasing down high-global-warming-potential HFC refrigerants, and updated ASHRAE Standards 15 and 34, which formally recognize A2L refrigerants and define requirements for their safe use.
According to G&D Chillers, A2L refrigerants are becoming the practical standard for glycol chilling applications in breweries, dairy, food processing, industrial processing, data centers, plastic injection molding, biogas and renewable natural gas, and medical and pharmaceutical facilities. The company said modern A2L chillers incorporate refrigerant charge-limit engineering, integrated leak detection, ventilation strategies, and controls and components designed to meet updated electrical and safety standards.
G&D Chillers said A2Ls are now standard across most of its platforms, while the company continues to expand its natural refrigerant offerings, including the Elite 290 propane (R290) line for applications requiring ultra-low GWP and reduced refrigerant charge. “At this point, everything we’re building is A2L,” said Paul Johnson, Director of Technology and R&D at G&D Chillers. “The industry is moving quickly, and customers need equipment that’s compliant today and serviceable long-term. A2Ls allow us to deliver the same performance and reliability G&D is known for while aligning with current regulations and standards.”
