Let's talk refrigerants: CO₂ powers safe, efficient and sustainable systems

The F‑Gas Regulation is an EU law that limits and phases down the use of refrigerants with high global warming potential (GWP), such as many hydrofluorocarbons (HFCs) traditionally used in cold rooms. Over time, these refrigerants will face reduced availability, higher costs, and bans in certain new equipment applications. Cold room operators using high‑GWP refrigerants must comply with requirements such as regular leak checks, certified servicing, and detailed record‑keeping.

Natural refrigerants like CO₂, with a GWP of 1, are not subject to phase‑down under the F‑Gas Regulation and meet all current and future compliance requirements. CO₂ refrigeration systems can provide reliable cooling performance while avoiding the regulatory restrictions and cost increases associated with high‑GWP refrigerants, making them a technically compliant and future‑proof choice for cold room applications.

With more than a decade of pioneering work in CO₂ refrigeration for both transcritical and subcritical systems, and thousands of successful installations worldwide, Danfoss offers unmatched expertise to guide cold room operators through this transition. From selecting the right CO₂ condensing units to providing advanced controls, components, and support tools, Danfoss ensures a smooth, efficient switch to sustainable cooling—delivering reliable performance, long‑term savings, and full regulatory compliance.
