Ammonia comes from the Latin word “hammoniacum”, which itself had its origins in ancient Greek. Acknowledged since time immemorial for its exceptional refrigerating properties, ammonia was first used in industry in 1876. It’s a natural gas whose chemical composition is a nitrogen atom linked to three hydrogen atoms: NH3 molecule. After having been overtaken by electricity and compressors in the 20th century, the modern challenges linked to the decarbonisation of today’s different working methods have seen ammonia make its great comeback: the possibility of developing a fully decarbonised refrigeration process.

The process is firstly composed of a phase during which refrigerant is produced. Ammonia changes phases, from solid to gas, thanks to the change in pressure. It evaporates and this creates cold temperatures. The precise temperature is consequently managed thanks to this change in pressure. The ammonia in the form of gas then enters the reactor where upon being put in contact with a mix of salt/graphite it is absorbed in order to be stored. Once the ammonia has been absorbed by the salt, a source of heat enables the ammonia to separate from the salt/graphite mix, which, once put under pressure again, returns to its solid form. It thus goes back to the evaporator. This is referred to as the reloading phase.

Our solid/gas sorption technology is based on the use of ammonia: the NH3 molecule. One nitrogen atom linked to three hydrogen atoms.
Temperature control is therefore one of the major challenges. This control is crucial for life and the living and can only be entrusted to people who have the expertise to master it.
We are committed to making thermodynamics accessible, so that we can put it to work for life and living beings, and thus have a positive and lasting impact on tomorrow's world by developing low-carbon solutions. /graphite it is absorbed in order to be stored.
