A2L refrigerants are a class of refrigerant blends designed to deliver a significantly lower GWP than many existing HFC refrigerants while maintaining performance in conventional systems. Common options used in refrigeration, such as R-454C and R-454A, are manufactured blends that are compliant with federal regulations under the Environmental Protection Agency (EPA) AIM Act. As a result, A2Ls offer a practical, cost-effective and technician-friendly solution for both new systems and remodels. They provide a more efficient alternative to higher-GWP refrigerants while also serving as a viable option in addition to natural refrigerants such as CO₂ or R-290—all while working within familiar system designs.

“The launch of our first A2L commercial refrigeration systems and merchandisers is an important step in helping our grocery and convenience customers navigate the industry’s transition to next-generation refrigerants,” said Tim Figge, CEO, Hussmann Corporation. “We’re committed to delivering innovative, reliable solutions that make it easier for retailers to adopt sustainable technologies while continuing to operate more efficiently. This milestone reflects our focus on supporting our customers with forward-looking refrigeration solutions that meet both today’s needs and tomorrow’s requirements.”

Hussmann now offers a portfolio of refrigeration systems designed for A2L refrigerants. Available options include the Protocol OLP with integrated or remote condensers, condensing units, small and large Krack 

Hussmann is committed to training technicians in the field that will be installing and maintaining A2L equipment. Refrigeration industry experts provide guidance and education on complete store designs with outdoor and indoor equipment that meets UL equipment requirements as well as building codes associated with A2L product installs.
