Refrigerants: The Case for CO2

Moving to sustainable refrigeration

With the increasing need for more environmentally friendly refrigeration solutions, the industry as a whole is moving towards more sustainable forms of cooling. Much of this is being driven by the F gas regulations, with HFC refrigerant phase downs having the greatest impact. 

The EU is cutting the availability of HFCs

The quota of F gases will be cut by 79% between 2015 and 2030. We are at the 2018 'cliff' - the most dramatic step in the phase down period. This is already having a significant impact on refrigeration system owners, who are struggling to obtain the quantities of F gases they need to safeguard the efficient operation of their plant.

Refrigerant bans and phase downs

HFO/HFC refrigerant blends are no longer a viable option for the long term. In 2020, HFCs with Global Warming Potentials (GWP) greater than 2,500 will be banned in new systems. And in 2030, all HFCs (even those considered 'greener') will exceed GWP and carbon restrictions. New strategies are needed now to navigate these challenges before it's too late.

Moving to natural refrigeration solutions now is critical

Many businesses have already made the transition to natural refrigeration solutions or are working towards it. It's not a question of if, it's a question of when.

Opting for natural refrigeration solutions enables system owners to:

  • Remain legally compliant
  • Keep their equipment running efficiently
  • Avoid unpredictable refrigerant price rises
  • Lessen their impact on the environment

What are natural refrigeration solutions?

CO2 is fast becoming the solution of choice for refrigeration system owners due to its versatility. It's suitable for retail and industrial applications, right from manufacturing facilities and processing plants, to distribution centres and live retail environments.  

Opting for a refrigeration system that uses CO2 offers:

  • Cost stability - the unpredictable price rises associated with F gas regulated refrigerants don't affect CO2
  • Future-proof cooling - no impending bans or phase downs associated with CO2 
  • Environmental credentials - it has a GWP of one, meaning it has a very low climate impact 
  • Option to reclaim waste heat and turn it in space heating and/or comfort cooling
  • A safe alternative as it's non-flammable and has low toxicity
