Carrier, meeting the challenge
of regulatory changes
The challenge raised by the European Union’s F-gas Regulation means the entire industry
must move to a new generation of refrigerants, that will not only protect the ozone layer
but also have a very low global warming impact. Carrier is facing this challenge head on.
The European F-gas Regulation 2014
European Union’s targets HFC
consumption related to CO2 equivalent
The 2014 revision of the regulation introduced bans for certain equipment using
hydrofluorocarbon (HFC) chemicals and a phase down scheme for HFCs
placed on the European market:
• Equipment bans target refrigeration applications and very low capacity
air to air conditioners (residential). There are no specific bans on liquid
chillers and hot water heat pumps using R-134a, R-407C and R-410A
refrigerants.
• The phase down is a step-by-step approach to lower the CO2 equivalent
in the HFCs that are placed on the market are gradually reduced through the
allocation of quotas by the European Commission to producers and importers
of bulk HFCs and importers of HFCs contained in pre-charged equipment. As a
result of the phase down, high Global Warming Power (GWP) HFC
consumption will be drastically reduced in 2030.

Carrier’s solution: PUREtec™
Carrier has been working over the past years on selecting the right refrigerant for
the future and has now taken the lead in introducing the next generation of
refrigerants on screw compressor chillers and heat pumps : PUREtec . With
PUREtec, Carrier offers a range of new customized solutions using a
refrigerant with zero impact on the ozone layer and nearly zero
global warming potential: HFO R-1234ze.

Identification of the best candidate to
replace HFC-R134a for all screw units:
HFO R-1234ze:
Limited impact on global warming GWP <1*
(similar to natural substances: CO2 GWP=1)
Not affected by the F-gas 2014 phase
