G&D Chillers Standardizes on A2L Refrigerants Across Glycol Chiller Platform April 6, 2026 Junction City, OR — April 06, 2026 G&D Chillers today announced that A2L refrigerants are now the standard across its glycol chiller platform. All new systems—excluding low-temperature applications—will be built using A2L-rated refrigerants, aligning with evolving regulatory requirements and updated safety standards across North America. For decades, glycol chillers have relied on high-global-warming-potential (GWP) HFC refrigerants. That landscape is rapidly changing as federal regulations, updated safety standards, and building code changes reshape how refrigeration systems are designed, installed, and approved. Under the U.S. Environmental Protection Agency’s American Innovation and Manufacturing (AIM) Act, high-GWP HFC refrigerants are being phased down, impacting which refrigerants can be used in new equipment and which will remain viable for long-term service. At the same time, ASHRAE Standards 15 and 34 have been updated to formally recognize A2L refrigerants and define requirements for their safe use. Building, mechanical, and fire codes across the U.S. are continuing to evolve in parallel. As a result, A2L refrigerants are emerging as the practical standard for glycol chilling applications across breweries, dairy, food processing, and industrial processing environments such as data centers, plastic injection molding, biogas and renewable natural gas, as well as medical and pharmaceutical applications. “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.” A2L refrigerants are classified by ASHRAE as low toxicity and mildly flammable with a low flame-propagation rate, enabling significantly lower global warming potential compared to traditional HFC refrigerants while maintaining the efficiency and performance required for industrial cooling systems. Industries that rely on glycol chilling demand precise temperature control, consistent uptime, and long equipment life. Standardizing on A2Ls ensures these systems remain compliant, serviceable, and reliable as regulatory requirements continue to evolve. Modern A2L chillers incorporate multiple safety and compliance measures, including: Refrigerant charge-limit engineering Integrated leak detection Proper ventilation strategies Controls and components designed to meet updated electrical and safety standards When engineered correctly and installed by trained professionals, A2L systems meet the same rigorous safety expectations as other commercial refrigeration systems. While A2Ls are now standard across most G&D platforms, the company continues to expand its natural refrigerant offerings, including its Elite 290™ propane (R290) line for applications requiring ultra-low GWP and reduced refrigerant charge. “Different facilities require different refrigerant strategies,” said Justin Thomas, General Manager of G&D Chillers. “A2Ls are the new standard, but they’re not the only solution. By supporting both A2L and R290 platforms, we help customers choose the right path based on their application, facility requirements, and long-term sustainability goals.” The shift to A2L refrigerants represents a long-term industry transition driven by regulation, safety standards, and environmental responsibility. For operators planning new equipment or evaluating existing systems, adopting A2L-based equipment helps ensure compliance, long-term serviceability, and reliable performance. G&D Chillers will continue providing engineering guidance, technical support, and educational resources to help customers navigate the transition to lower-GWP refrigerants with confidence.
