“Natural” refrigerants in data centres
1st February 2026
BELGIUM: The “natural” refrigerants market accelerator Atmosphere ((formerly Shecco) has published a new report giving an overview of the state of “clean cooling” in the data centre sector.
The 88-page report includes an overview of the market, a description of the technologies available and an rundown of the regulatory landscape across the world. It also features nine articles based on in-depth interviews with cooling system and component manufacturers. These companies include Alfa Laval, BAC, Carel, Fenagy, Jaeggi, Kelvion, Secon, SWEP and Zudek.
The report defines “clean cooling” as mechanical cooling with natural refrigerants, liquid cooling systems that use non-fluorinated refrigerants, heat pumps and the components that make it possible to recover and reuse waste heat, and free cooling via dry, hybrid or evaporative coolers.
“This is the first report to focus strictly on clean cooling in data centres, and it provides valuable insights into the state of natural refrigerants in the industry,” explained the report’s lead author Michael Hines.
