More climate protection: with refrigerants from Westfalen.
Discover our pioneer: Pronat® R-744, TÜV-certified as a climate-neutral product.
Where in the past ice blocks were harvested in winter for cooling and stored until summer, today refrigeration systems ensure the right temperatures. Whether for normal cooling, deep-freezing or air-conditioning: the refrigerant is the operating material of a refrigeration system. It circulates, is evaporated, compressed, liquefied and expanded. Whether in refrigeration or air-conditioning systems, in chillers, heat recovery systems or heat pumps: refrigerants are responsible for heat transport. The diverse fields of application ensure a wide range of requirements.
For some years now, however, the refrigeration and air conditioning industry has been in a state of flux, driven by the F-Gas Regulation. Its goal: more climate protection. While refrigerants with a high Global Warming Potential (GWP) are gradually disappearing from the market, more climate-friendly but often flammable refrigerants are gaining in importance.
Then Westfalen is the right place for you!
Whether synthetic or natural, low-GWP or climate-neutral, whether via our cylinder gas online shop or your local sales partner - we reliably supply you with what you need.
You want details? We do!
Which refrigerants best suit my requirements? What's new with the F-Gas Regulation? What do I have to bear in mind when dealing with flammable refrigerants? In the menu item Fields of application you will find detailed background information and expert knowledge about our products and topics in the refrigeration and air conditioning industry.
Our product range consists of natural, halogen-free refrigerants and synthetic refrigerants. Would you like to get an overview? Or do you want to search for a refrigerant quickly and specifically? The following overviews contain the product names, GWP values, safety classes according to ISO and further information. The individual refrigerants are linked directly to our online shop - here you will find further details on the respective product, including vapour pressure tables and product and safety data sheets.
The name already gives it away: The natural and halogen-free refrigerants are substances that also occur in nature: Carbon dioxide (Pronat® R-744 as a TÜV-certified, climate-neutral product) and hydrocarbons (e.g. propane and ammonia). They are all characterised by the fact that they have no or a very low GWP value and are particularly climate and environmentally friendly. Natural refrigerants are therefore becoming increasingly important in refrigeration and air conditioning technology. It should be noted that some natural refrigerants are flammable (e.g. propane and ammonia) and/or toxic (e.g. ammonia) gases - with corresponding requirements for use.
With synthetic refrigerants you can achieve particularly high efficiency in your system concepts. As part of the phase-down of the F-Gas Regulation, synthetic refrigerants with high GWP values are slowly disappearing from the market. New products with low GWP values can be used as alternatives or substitutes. However, refrigeration companies must take into account the higher flammability of refrigerants with lower GWP values. By the way: We take back your used synthetic refrigerants for reprocessing.

We take it very seriously: our quality assurance from incoming analysis to filling guarantees consistently high product quality. You can also rely on the security of your supply: we regularly invest in our filling and logistics sites in Europe.
Refrigerants that are contaminated in their composition or distributed in non-refillable disposable containers carry a high potential of danger. Absolute caution is required when handling illegal refrigerants. This is because, in addition to legal consequences, there are risks for occupational safety, health hazards and long-term damage to refrigeration and air-conditioning systems and to the environment. Illegal trade continues to undermine the goal of the F-Gas Regulation to reduce greenhouse gases.
The Westfalen Group therefore relies on high product quality in the sale and reconditioning of refrigerants. Our customers can be sure that they are in good hands when buying refrigerants. Whether in environmental, occupational safety or quality management - Westfalen meets the highest quality requirements in all areas.
We support the EFCTC's "Word of Honour - Say No to Illegal HFCs" initiative and have given our word of honour in the fight against illegal HFC refrigerants. To do this, we work closely with our partners throughout the supply chain to ensure that we only source HFCs from reputable and legal sources. So you too can use our products and services with confidence.
Join us and give your word of honour too
If you become aware of any incidents involving illegal F-Gas products and trafficking, report them to the EFCTC Action Line.
The F-Gas Regulation regulates refrigerants with a high global warming potential (GWP) and ensures a change towards climate-friendly refrigerants with a low GWP. We have summarised the most important changes and effects of the regulation for you and are also available for questions and answers.
We take back your used refrigerants and recycle them in the most effective and resource-saving way possible. If your refrigerant is unmixed, we recycle it. If your refrigerant is not sorted by type, we recycle most of it as a raw material for the chemical industry. Contact us, our experts will be happy to advise you on the reprocessing of your refrigerants.
Vapour pressure tables, product and safety data sheets for all products are available for download in our online shop. Use the menu structure or the search function to find the product you are looking for. You can also use these functions without a shop log-in.
You can obtain our refrigerants in all common cylinder containers and drums. You can see which ones these are for a particular refrigerant in the online shop under "Delivery forms". Use the menu structure or the search function to find the product you are looking for. You can also use these functions without logging in to the shop.
Westfalen is active with its own locations in Germany, the Netherlands, Belgium, France, Austria and Switzerland. In individual cases, delivery to other countries is also possible. Please feel free to contact us if you have any questions.
