Menerga's use of natural refrigerants

Environmentally friendly refrigerants for sustainable refrigeration

Our deep-rooted conviction regarding sustainability and environmental protection is reflected in particular in the use of water as a refrigerant. Water is a highly sustainable option as it has no harmful environmental impact compared to conventional refrigerants and minimises the negative impact on climate change. This innovative approach goes hand in hand with our efforts to reduce our environmental impact and meet our climate targets.

Controlling environmental impacts

Tackling climate change through REACH and F-Gas regulations

The REACH Regulation and the F-Gas Regulation are two important legal instruments of the European Union that contribute to controlling environmental impacts and climate change related to chemicals and refrigerants. The F-Gas Regulation aims to reduce emissions of fluorinated greenhouse gases (F-Gases) and mitigate climate change by setting quotas for the placing on the market of these gases, in particular for gases with a high global warming potential (GWP) above 150.

PFAS ban in air conditioning and ventilation technology is imminent.

PFAS-free refrigerants

The upcoming legislation to restrict PFAS in air conditioning and ventilation technology is of great importance for the environment and health. PFAS (per- and polyfluorinated alkyl compounds) are highly polluting chemicals used in many refrigerants. Their use contributes significantly to global warming and poses a threat to the environment. The planned law aims to reduce or ban the use of refrigerants containing PFAS, which is an important step towards reducing the climate impact of air handling and ventilation technology.

Menerga's use of natural refrigerants

Natural refrigerants
The decision to use natural refrigerants such as water and propane underscores our commitment to technologies that are not only environmentally friendly, but also future-proof.

Efficient solutions
By using these refrigerants, we can develop energy-efficient cooling solutions that not only improve the performance and reliability of refrigeration systems, but also help to minimise the negative environmental impact. In this way, Menerga shows how innovation and sustainability can be in perfect harmony.

Innovation for the future

Carbon dioxide as refrigerant

Sustainable development

At Menerga, we are always striving to continuously improve our cooling solutions and make them more environmentally friendly. One exciting development we look forward to in the future is the use of CO2 (carbon dioxide) as a refrigerant. This groundbreaking innovation will further drive our commitment to sustainability and environmental protection.

Here are some of the main advantages of CO2 as a refrigerant:

Environmental friendliness

Carbon dioxide is a natural refrigerant and does not contribute to the destruction of the ozone layer. Compared to synthetic refrigerants, CO2 has a very low global warming potential (GWP) and thus makes a small contribution to climate change.


CO2 is available in large quantities. It can be extracted from natural sources or recycled as a by-product of industrial processing. This makes it a sustainable choice.

Energy efficiency

CO2 has excellent thermodynamic properties that lead to improved energy efficiency in many applications. This means that CO2-based refrigeration systems usually consume less energy and are therefore more cost-efficient.


Compared to some other natural refrigerants such as ammonia, CO2 is non-toxic and non-flammable. This facilitates the handling, storage and maintenance of CO2 refrigeration systems and increases safety.


CO2 is suitable for a wide range of refrigeration applications, from commercial refrigerators to industrial refrigeration systems. It can be used in both high temperature and low temperature applications.

Long-term availability

As CO2 is a natural resource, its availability is secured in the long term and is not dependent on geopolitical factors or limited occurrences.

CO2 as a refrigerant

Environmentally friendly alternative

It is a natural refrigerant that has no harmful effects on the environment. Compared to conventional synthetic refrigerants, CO2 is an environmentally friendly alternative that does not release harmful greenhouse gases.

The use of CO2 as a refrigerant offers a number of advantages that make it an attractive option for cooling-friendly applications.
