    Are you ready for the R404A phase out?

    12th Apr 2017
    Many manufacturers are still using R404A in commercial and professional cabinets. Recently Honeywell (one of the largest manufacturers of refrigerants) stated that they intend to stop selling high GWP refrigerants such as R404A in Europe from next year (2018). The price of R404A has risen dramatically over the last year and is predicted to continue increasing (consecutive monthly price rises of 25% and 30% have recently been announced by Chemours). There is now a strong business case to move to a low GWP refrigerant alternative.
