HFCs and HFOs towards the ban in Europe?

On July 15 2021, five member states of the European Community – Germany, the Netherlands, Norway, Sweden and Denmark – published their intention to submit a joint restriction proposal under the European REACH regulations for per- and polyfluorinated alkyl substances (PFAS) to the European Chemicals Agency (ECHA) by July 2022.

The European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation has authority over chemicals that can be produced and used within the EU. Any modification to this regulation has the direct consequence to override the F-gas regulation. This proposal, indeed, includes any substance that has a CF2 group or a CF3 group – properties shared by HFC and HFO refrigerants.

It is known that the degradation of HFOs and HFCs when released in atmosphere can produce trifluoroacetic acid (TFA) which effect is persistent and has the potential to harm the environment, marine life and humans. The F-gas regulation addresses global warming, but does not address concerns about the persistence and accumulation of TFAs given the continued development and application of F-gases such as HFOs.

The F-gases under threat could include a range of lower and low GWP alternatives common to the refrigeration and air conditioning industry including the HFCs R32, R125, R134a, R143a, R152a and the HFOs R1234yf, R1234ze(E), R1336mzz(E), R1336mzz(Z), R1233zd(E) and R1224yd.

This is another piece of news that confirms that the only viable way to save our planet and human health is the use of natural refrigerants, such as propane R290 and isobutane R600a.


Great news from IPCC: the new GWP of R290 is much lower than 3

Two months ago, the Intergovernmental Panel on Climate Change (IPCC), released a first version of the report Climate Change 2021 – The Physical Science Basis which will be definitively released in September 2022 and which contains the new official GWP (Global Warming Potential) values for hydrocarbons.

This report show that propane R290 has a 100-year GWP of 0.02, much lower than the traditional assumed value of 3 because of its three atoms of carbon (C3H8). However, 3 is a very low value if compared with most popular HFCs, but still many times higher than the new value. Isobutane R600a, another natural refrigerant gas, also has a new 100-year GWP much less than 1 and equal to 0.006.

On the other hand, the new 100-years GWP of the R32, that is considered the HFC with the lowest GWP, changed from 675 to 771. For this reason, it most likely no longer will be possible to use it in new equipment from January 1 2025.

In conclusion, the only way to save our planet is to promote an increasingly consistent use of natural refrigerant fluids such as propane R290 and isobutane R600a. Euroklimat, currently a leader in the market of R290 chillers and heat pumps, has now been active in this sector for almost 20 years, producing units that protect the environment and the health of all of us.


Euroklimat leader in the market of R290 chillers already in 2014

Today we celebrate the now famous "Throwback Thursday" by recalling the participation of Euroklimat in "Chillventa 2014", an important biennial exhibition with a theme aimed at new technologies applied to chillers and heat pumps.

Already 7 years ago, Euroklimat had developed the first ranges of natural chillers containing R290 propane (for industrial process and comfort applications) and thus began to offer them to the market, resulting a pioneering company in the field of refrigeration that protects the environment.

In fact, the first prototype of a R290 chiller branded Euroklimat was produced in 2004 and shortly after the company was the first in Italy to obtain the appropriate certifications (ISO 9001 and PED) for the construction and assembly of this unit type.

For many years, therefore, Euroklimat S.p.A. continuously invests numerous resources to increase the effectiveness and efficiency of propane refrigeration machines. In fact, as a demonstration of what has been described, in 2018 Euroklimat was awarded the European INNODRIVER tender through the range of latest generation R290 HERA heat pumps.

To date, the company has more than 1600 installations of propane units, a long experience that allows it to be distinguished from many other manufacturers in the sector.
