The natural choice for future‑proof refrigeration systems
Many refrigeration systems still rely on refrigerants that are being phased out, but there’s a smarter, future‑proof alternative.
CO₂ combines high performance, proven safety, and long‑term sustainability and cost efficiency in one solution.
With no phase‑out risk under current or future rules, CO₂ is a reliable investment that keeps your operations efficient, compliant, and ready for the years ahead, a choice your customers and the planet will value.
Understanding the effect of F‑Gas Regulations on your business
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.
Case Study
How to get started with CO₂?
CO₂ is not a new refrigerant. It has been used for over a century and today, Danfoss is leading its modern renaissance with proven technology and thousands of successful installations worldwide. The Wiese City Butchery’s refurbishment case study shows how Danfoss CO₂ condensing units make the switch simple, with fast installation, easy commissioning, and reliable operation. With a GWP of just 1, CO₂ meets all future F‑Gas requirements, ensuring a long‑term, future‑proof investment that delivers energy efficiency, low noise, and sustainable cooling for cold rooms and commercial applications. As a trusted partner with deep expertise, Danfoss provides the components, tools, and support needed to start the CO₂ journey with confidence and secure lasting value.
