Natural Refrigerants

Natural refrigerants are an important factor to consider in your system design and should be considered for all of your chilled requirements. More details on the 2020 F Gas Regulations that have forced these changes can be found on the site, but for now we focus on the natural refrigerants that are vital to all new refrigeration installations.

What are natural refrigerants?

Natural refrigerants are substances that exist naturally in the Earth’s atmosphere and, unlike synthetic refrigerants that are traditionally used, they have zero ozone depletion potential (ODP). This means they will have no negative effect on the Earth’s ozone layer if released to atmosphere. They also have a very low, or even no global warming potential (GWP), which is vital in their compliance with the new F Gas Regulations of 2020. As a result, they are classified as a “green” environmentally friendly refrigerant solution for all chilled applications.

Natural refrigerant gasses are also considered “future-proof” as it is unlikely that any new environmental legislation will prohibit or severely limit their use, meaning that you can rely on this kind of refrigeration for years to come.


The most widespread natural refrigerants used in refrigeration applications today are:

  • Carbon Dioxide (CO2, R-744)
  • Hydrocarbons such as propane (R-290), isobutane (R-600a) and propylene (R-1270)
  • Ammonia (NH3, R-717)

Other natural refrigerants include water (H2O, R-718) and air (R-729), although these are not efficient as a refrigeration medium.

Our experienced team specialise in the application of natural refrigerants in display cabinets and full refrigeration systems of many differing sizes and options. We actively promote their use over the more traditional gases and support the industry change to environmentally friendly solutions.
