REFRIGERANTS


based systems that will last for decades, and comply with EU regulations, rather than the short-lived synthetic alternatives. Proven refrigeration and heating technology can be tailored to provide innovative solutions using ammonia that are sufficiently robust to fit any application, whether it’s for cooling in a brewery or for the pasteurization process in a dairy. Ammonia is the most cost-effective, most efficient option for all types of industrial equipment and is already used as a refrigerant in all fields of industrial refrigeration.


Why make ammonia your first-choice natural refrigerant?


Ammonia could be described as a back to the future gas. It’s nothing new and has been around for a very long time, yet it’s a very modern solution. Low charge ammonia is the modern term for low-pressure technology with very low total cost of ownership, which has evolved to meet the demands of the 21st Century. Ammonia is completely carbon neutral making it the perfect sustainable alternative to other refrigerants. It is also thermodynamically 40% more efficient giving it a wider application in heat pumps (another sustainable tech GEA is driving industrial usage of). Moreover, ammonia lowers carbon emissions in all its applications while offering high-performance, energy efficient, sustainable cooling and heating solutions. Traditional ammonia installations are considered a ‘no brainer’ in key regions such as Europe, the Far East and the United States as more food manufacturers, distribution centers and retailers with refrigeration systems join the trend. Latest figures for low charge ammonia installations in 2021 have seen growth in Europe of 11%, US 13% and Japan 24% on the previous year (source ATMO Report).


Safety is a key factor


Some potential end-users might have concerns about using ammonia-based refrigerants but those fears are completely unfounded as experienced refrigeration companies have expert knowledge to install all necessary safety and ventilation equipment in accordance with local rules. Furthermore, fully qualified and trained service teams will ensure that all equipment is maintained to the highest standards.


It is safe to use on any land installations


from factories to district heating. Ammonia based cooling systems aboard vessels at sea are nothing new, as many users in the marine industry will testify. GEA has delivered multiple projects featuring solutions using natural refrigerants for freezing, preserving and storing seafood on board fishing vessels. David Blankley, director management for advanced refrigeration, GEA Heating &


Refrigeration Technologies says: “Ammonia is ideal for many different applications as it’s a very versatile refrigerant for every range of temperature levels. It is proven so we’re not reinventing the wheel. Over recent years we have witnessed far reaching bans on chemical substances that damage our environment. "With the EU’s recent vote to ban F-gases even sooner than expected, it is only with a natural refrigerant that customers can truly feel secure about the future. GEA has vast experience and knowledge in developing and installing highly- efficient natural refrigerant-based cooling & heating systems globally. When you choose sustainable solutions, it makes complete sense to choose a sustainable refrigerant to match!” Patrick Ackens, senior vice-president sales,


adds: “Ammonia is a very efficient refrigerant; therefore, it is sustainable because you consume less energy than with other systems. The gas is found in nature and it’s one of the cheapest refrigerants overall. It’s not synthetic or man- made or a production by-product – so it’s ozone and climate friendly with zero global warming potential. "As a future-proof natural refrigerant, ammonia also has a long lifespan so it is a great investment compared to other refrigerants that you may have to reinvest in after 10 years, in order to update or change to another one. If you invest in ammonia, your investment is safe for the next 30 to 40 years or even more.” Considering these ambitious new targets


ratified by the EU, organizations have nothing to lose and everything to gain from adopting advanced natural refrigeration technologies. Ammonia is not only cheap and safe – it is also the best choice to further reduce running costs and emissions.
