Wiesbaden supermarket is all CO2
19th October 2026
GERMANY: A recently reopened supermarket in Wiesbaden claims to be the first to use CO2 refrigerant in all its commercial refrigeration, heating and air conditioning.
The installation in the Denns BioMarkt was the result of close collaboration between supermarket owner Dennree GmbH, installation partner Polaris R Laude GmbH and Daikin.
The project includes a combination of Daikin’s CO2 Conveni-Pack, AHT counters and Daikin’s CO2 VRV, handling the refrigeration, heating and cooling across the sales floor.

For Dennree, Europe’s leading organic food retailer with over 400 Denns BioMarkets across Germany and Austria, sustainability is a design principle being applied to every aspect of how its stores are built and operated.
The CO2-specific requirements, such as K65 pipework, were said to have been straightforward to plan for and execute, while Daikin’s Conveni-Pack and VRV plug-and-play approach meant the project came in without complications.
Based on this first live retail installation in Europe, Polaris is already planning further CO2 VRV projects in response to growing market interest.
