LEBRUN water-cooling systems find their originality in using ammonia (NH3) as the refrigerant.

Indeed, for that type of applications, the use of ammonia made these water-cooling systems perfectly adapted to countries where ecological standards stimulate the use of natural and environmentally “safe” refrigerants.


Ammonia water-cooling systems working in direct expansion. Their capacity ranges from 50 kW up to more than 500 kW (glycol water + 6°C/+12°C). They can be automatically controlled through PLC and electronic expansion valves. They can also be equipped with silent air condensers in order to reach extremely low noise levels.

Assembly and tests are performed in workshop, according to the PED 97/23/EEC standard.
