CO₂ (R744)
CO₂ refrigeration systems: design, installation and service
We design, install, commission and service CO₂ (R744) refrigeration systems throughout Poland, mainly in large-format stores and industry. CO₂ is a natural refrigerant with a GWP of 1 and safety class A1 (non-flammable, low toxicity). That is why it is not affected by the restrictions of F-gas Regulation (EU) 2024/573, which phase out high-GWP HFC refrigerants.

A small team that designs, installs and services
We are a team of six people with three service vans, based in Majdan, just beyond the eastern border of Warsaw. The same people design a system, install it and then service it. Since 2021 we have completed more than 300 projects.
