Green Refrigerants

Today, numerous green refrigerants are available on the market, with a low environmental impact, all measurable in terms of ODP (Ozone Depletion Potential) and GWP (Global Warming Potential), which expresses the impact that a refrigerant would have on global warming if released into the atmosphere. We have chosen to select the most suitable green refrigerant for each product family, looking for the best compromise between rational use of energy, respect for the environment, and competitiveness.

R513A
We have selected the R513A refrigerant for our screw compressor units, a viable alternative to R134a. This refrigerant is a mixture of R1234yf (56%) and R134a (44%), non-toxic and non-flammable (Class A1 of ASHRAE 34, ISO 817), which guarantees a reduction in GWP of -56% compared to R134a. There are numerous ranges of chillers, heat pumps, and multipurpose units already available with the new refrigerant R513A and are all identified by the acronym G05.

R454B
For units with rotary hermetic scroll compressors, we have selected the new R454B refrigerant, with a GWP 76% lower than its predecessor R410A. Thanks to a 10% reduced coolant charge and improved proven efficiency, R454B offers the best trade-off between minimizing environmental impact and rational use of energy for these units. R454B consists of 69% R32 and 31% R1234yf and is classified as A2L (non-toxic but slightly flammable), in safety group PED 1. To enable proper management of transport, storage, and installation, as well as subsequent maintenance, we provide our customers with dedicated tools that simplify and make the main operations related to the delivery and start-up of the units completely secure. Units using this refrigerant are identified by the acronym G06.

HFO: fourth generation refrigerants
The flagship of green refrigerants is HFO (Hydro-Fluoro-Olefine), or fourth generation refrigerants, which have zero ODP and negligible GWP (<1).
For our TECS2, TECS2-W, FX, TRCS2, TRCS2-W, FR, and i-FR chiller ranges, we have therefore chosen to replace R134a with the new HFO R1234ze refrigerant, which has a near-zero GWP and a dissolution time in the atmosphere of only 2 weeks, compared to the 14 years of R134a. Despite being slightly flammable, its high compatibility with standard components and operating performance similar to that of R134a make the new HFO 1234ze the perfect alternative to HFC refrigerants.
