A-Gas says installers and end-users should make the switch to reclaimed refrigerants as quickly as possible with the ban on the use of virgin R404A (GWP 3922) now in effect.
From January 1, virgin refrigerants with a GWP of 2500 or greater can no longer be used in new installations. Maintenance has also been affected as systems with a charge size of 40 tonnes CO2 equivalent or greater – more easily understood as around 10kg of R404A – cannot be serviced using virgin material with this high GWP.
“A-Gas has invested heavily in expanding reclamation facilities in the UK and in Europe. The news that major refrigerant suppliers are removing all stocks of virgin R404A and R507A from sale in the European market reinforces the importance that the switch to reclaimed gases must gain pace if the industry is to manage this change.
“It is also key that installers and end users understand the difference between reclaimed and recycled refrigerants. Recycled refrigerant is a handy quick-fix which is cleaned up and can only be used on site. While reclaimed refrigerant is product that has been reprocessed by a licensed facility to the industry standard AHRI 700 to match that of virgin product. It is purified, certificated and guaranteed to be returned to the same standard as virgin material.
“The demand for reclaimed R404A will grow and this will have an effect on supplies. While low GWP alternatives are in the long run the preferable choice, reclaimed gases are part of the future as they make use of material that has already been produced, helping to prolong the life of equipment and reducing the burden on producing new, quota restricted, material.”
