Environmental Benefits

  • Many Decades Ago

    The sun shone on earth, heating it perfectly. The ozone layer protected us from harmful rays and heat left the atmosphere during the night. Our contemporary societies destroyed this balance, due to the drastic impact on global warming caused by the depletion of the ozone layer and greenhouse gas emissions. 15% of this imbalance is caused by refrigeration.

  • We have used R22 for years...

    R22 has a global warming potential of 1800, and has a major and detrimental effect on the ozone layer. To stop its destructive impact on our ozone layer, the Montreal Protocol banned R22. Then we replaced it with R404.

  • R404

    R404 has no impact on our ozone layer, but its global warming potential is 3900, so it is twice as harmful as its predecessor. Currently, there are different alternatives, like HFOs...

  • HFOs

    HFOs are a mixture of F-gases that are not harmful to the ozone layer and don’t emit greenhouse gases, but they do spread into the water table and pollute our water! As another alternative, there are natural refrigerants that have no impact on our environment, like ammonia and CO2.

  • Ammonia

    Ammonia has no impact on either the ozone layer or global warming. However, ammonia is flammable, corrosive and harmful if inhaled. The only one left is CO2...

  • CO2

    Because it has no impact on the ozone layer, almost no impact on global warming and is non-toxic to humans, CO2 is THE sustainable solution.

CO2, Why and How?

The facts:

  • Current refrigeration systems, such as those in supermarkets for example, use 1,000 to 2,000 kg of HCFC or HFC per establishment.
  • In North America, 30% of these refrigerants leak into the atmosphere.
  • 99% of gas refrigerants complete their life cycle in the atmosphere.
  • 1,000 pounds of refrigerant in the atmosphere is equivalent to the effect of 400 cars on the road for one year.
  • A synthetic refrigerant leak is equivalent to 1200 cars on the road for one year.


  • 0 Tolerance for leaks.
  • Global Consensus towards 0 F-Gas (The Kyoto Protocol, The Consumer Goods Forum, the United Nations with the CCW, EIA and the European Parliament, the EPA and GreenChill the United States, the PACC 2020 Canada, etc.). Click here to learn more about it.

The solution: 

  • CO2 is a natural, safe and inexpensive refrigerant (12 times more economical than traditional HFC).
  • Its effect on the climate is 1,500 to 4,000 times less than that of synthetic refrigerants (see planet diagram above).
  • The heat transfer characteristics of CO2 are more attractive than synthetic refrigerants. This increases energy efficiency in systems.
  • CO2 must operate at high-pressure, which can increase system efficiency, reduce the size of components and piping and enable the design of more compact systems.
