A-Gas urges the industry to replace R404A with low GWP alternatives

A-Gas is urging the refrigeration industry to waste no time in making the switch to low GWP refrigerants Solstice® N40 (R-448A) and Opteon® XP40 (R-449A) before shortages of R404A begin to bite.

The latest round of F-Gas Regulations will affect the availability of R404A – the most widely used refrigerant in the industry – as high GWP refrigerants are subject to a cap and phase down. 

Opteon XP40 (R-449A) and Solstice N40 (R-448A) are now available widely through refrigerant wholesalers and are a perfect solution for end-users looking for alternatives to R404A. They have a lower GWP than R407A and R407F (Genetron® Performax LT™); the two medium GWP alternatives currently available. Both also offer improvements in energy efficiency and are a great choice where discharge temperature is a concern.

A-Gas Managing Director John Ormerod said: “Time is running out but some contractors are still ignoring the fact that supplies of R404A will shrink over the next two years and by 2018 there simply won’t be enough to go around. It is no good making the switch at the last minute – there is a huge bank of equipment out there which will have to be updated with low GWP refrigerants.”

“The low GWP credentials of Opteon XP40 and Solstice N40 – a more than two-thirds reduction on R404A – make them an obvious choice for those considering a change of refrigerants. They are also very closely matched to R404A in terms of their refrigeration capacity. Now is the time to change to these new low GWP refrigerants.”

Opteon XP40 and Solstice N40 are suitable for medium and low temperature systems and there is little to choose between them in terms of performance.  A big advantage over R407A and R407F is that they have lower discharge temperatures – well below 100°C – and this means the compressor is likely to last longer.

Energy efficiency is also a plus point for the new refrigerants with savings of between five and ten per cent to be made on the running costs of a large supermarket or cold store operation.

Solstice N40 and Opteon XP40 are available today for those looking to move away from R404A. Locate your nearest A-Gas stockist here.
