Refrigerant NH3

With a GWP value of 0, ammonia (NH3, R717) is ideal for sustainable and long-term refrigeration solutions. The excellent heat transfer properties of ammonia make it the preferred choice for rather high capacities in large-scale refrigeration and industry. As a rule, these are used for cold water/brine production and, for example, reliably supply production and storage processes with cold.

Our ammonia refrigeration systems fulfill every cooling task efficiently and safely, in compliance with all applicable standards and laws. In addition, our ammonia-based refrigeration systems are eligible for subsidies in accordance with the BAFA guidelines, making them an even more attractive choice.

Ammonia (NH3) has established itself as an excellent refrigerant, particularly for applications with high performance requirements. However, ammonia also has enormous potential for commercial systems in the medium capacity range. There are several reasons that make ammonia so attractive as a refrigerant. 

Firstly, ammonia has first-class environmental properties. With a global warming potential (GWP) and an ozone depletion potential (ODP) of zero, ammonia has no impact on global warming or the ozone layer, making it one of the most sustainable options.  

On the other hand, ammonia impresses with its efficiency and future-proofing. With its excellent heat transfer properties, ammonia is mainly used efficiently at high outputs. In addition, there are currently no plans to restrict or forbid this refrigerant by law or regulation.  

All in all, ammonia is proving to be a versatile and sustainable refrigerant that is both ecologically and economically beneficial and will therefore be more widely distributed in the future.  

Ammonia (NH3 or R717 as a refrigerant) is a natural refrigerant with a long history. Its physical properties require proper handling in order to ensure safe system operation.  

Ammonia is toxic: in high concentrations it can cause serious health problems such as irritation of the eyes, throat, and lungs. In extreme cases, it can cause asphyxiation. It is important to take appropriate safety measures to limit exposure to ammonia and ensure adequate ventilation.  

Even at low concentrations in the ambient air, ammonia has a high signalling effect on us humans. However, the concentrations that occur in our systems are not harmful to health. As a positive side effect, it can be assumed that all ammonia systems are 100% leak-proof.  

Ammonia reacts with metals such as copper and zinc, which can lead to corrosion and possible failures in the corresponding systems.  

Because of the classification in safety group B2L, precautions must also be taken with regard to flammability. 

The worldwide use of R717 shows that these properties can be well controlled by safety measures and techniques, and that cooling tasks can be managed efficiently.  

The global warming potential (GWP) is used to compare the effects of various greenhouse gases on global warming. Carbon dioxide is used as a reference value and has a value of 1. The unit of measurement is given in a kg CO₂ equivalent. 

The higher the GWP value, the more the substance contributes to the greenhouse effect on global warming. 

The GWP value is used in the F-Gas Regulation and specifies the limit values for restrictions and bans on refrigerants.
