R404A Refrigerant Replacement

At the end of 2014, The EU introduced regulations on the use of fluorinated greenhouse gases, leading to the current phase out of refrigerant gases with a high Global Warming Potential (GWP).

R449A, the recommended R404A replacement, is a next-generation refrigerant that combines excellent cooling performance with improved energy efficiency and a significantly lower environmental impact. This means that R449A not only meets the new legislative requirements but can also reduce running costs while simultaneously extending the lifespan of the unit.

With a GWP of just 1397, R449A provides a long-term refrigerant solution. By comparison, R404A refrigerant gas has a GWP of 3922.

The R404A refrigerant phase out is due to be completed at the end of 2018. As this date approaches, demand for R449A is likely to increase dramatically, so we are advising clients to act sooner rather than later in planning the replacement of their R404A. If you would like to discuss this, please get in touch.
