In the ever-changing landscape of industrial process cooling, innovation and sustainability play a crucial role. Increasing operating temperatures, reducing greenhouse gas emissions and improving energy efficiency are the challenges of the process cooling markets to which cosmotec responds with its new range of multi-scroll chillers WPA and free cooling equipped with the low-GWP refrigerant R454B.


New refrigerant R454B: a step forward for the environment

The refrigerant R454B is a low-GWP 467 HFO blend of 69% R32 and 31% R1234yf and represents a significant step forward compared to traditional refrigerants such as R410 (GWP 1924). By using R454B, WPA units contribute substantially to the reduction of greenhouse gas emissions, help meet increasingly stringent environmental regulations and corporate sustainability goals.


Advantages of new WPA chillers in R454B

  • Superior efficiency: the combination of scroll technology with R454B refrigerant allows WPA units to achieve higher efficiency levels than the R410A version, which translates into lower operating costs, making the WPA an economical as well as environmentally friendly choice.
  • Environmental compatibility: due to its low GWP, R454B is not subject to the restrictions of the F-Gas regulation 2024/573, which from 2027 will prohibit the use of refrigerants with a GWP greater than 750 for chillers with a rated cooling capacity greater than 12 kW. WPA units in R454B are therefore a long-term solution, as they will not require any retrofitting in the future.
  • Reliability and durability: WPA units in R454B are designed for 24/7 use and are adaptable to any critical infrastructure project. All units are individually tested at the factory and function-tested for maximum reliability and durability.
  • Flexibility of application: the wide range of configurations (chillers and free cooling) and numerous options and accessories allow the WPA R454B to be easily adapted to different industrial process applications, where precise temperature control is essential.
  • Training and safe handling: R454B is classified as A2L slightly flammable (non-toxic), so cosmotec can provide all the documentation and specific training to ensure proper handling of transport, storage and installation of units with R454B.


WPA units in R454B are cosmotec answer to the transition to environmentally friendly process plants, a smart choice for a more sustainable future.
