 From 1st January 2015 topping up of all HCFC systems will be banned in the United Kingdom.

European legislation, driven by the Montreal Protocol, has established the timely phasing out of hydrochlorofluorocarbons (HCFCs) that contribute to climate change through ozone layer depletion and global warming.

Typical HCFC Refrigerants found in Fruit Storage are R22 and R409a (FX56), R409a originally being a replacement for R12 after the ban on CFC’s back in the 1990’s

 Whereas it will not be illegal to own systems containing these refrigerants, from 1st January 2015 any refrigeration service provider will not be able to add to or re-charge systems with the above refrigerants by law.

  In addition to the above, refrigerant suppliers are predicting a shortage of suitable reclaim cylinders due to the high volumes of plant retrofits expected. STS would urge our customers with HCFC refrigerants to ACT NOW and avoid possible lengthy plant down time.
