Conçu sur le principe du moteur Ericsson, l’Ecocompresseur d’Ananké est un module de cogénération qui permet la production simultanée d’air comprimé et de chaleur utile à partir de n’importe quelle source de chaleur supérieure à 450°C (chaleur fatale, combustion de biogaz…). Cette solution rend possible la valorisation des pertes thermiques, notamment dans les secteurs tels que la métallurgie, la verrerie ou la chimie.
Tous les éléments du moteur sont concentrés dans un conteneur facilitant ainsi l’installation sur le site de nos clients sans passer par le vecteur électrique. Basée sur le principe du Plug & Play, l’implémentation du module s’effectue par l’installation d’un bypass en pied de cheminée. Situé en aval du process industriel, ce dispositif ne perturbe en rien la production du site.



The production of compressed air consumable directly enables higher yields. The customer enjoys better control over its production costs thanks to the recovery of waste within its company, thus minimising the purchase of external energy.

All engine components are encased in a container which is not connected to the electrical network. This specific feature makes it much easier to set up on customers’ sites. This plug&play module is set up by fitting a bypass at the chimney base. Plus, this equipment will never disturb the production thanks to its location downstream of the industrial process.

The engine configuration and its innovations allows a higher efficiency than other externally heated valve engines. The competitive unit cost is key to an optimal return on investment.



This patented technology has been rewarded by the National Innovation Award (Grand Prix National de l’Innovation) in 2015. The young innovative company also won the i-Nov (PIA3) contest of ADEME in 2019.

An innovative system has been developed in order to adapt the  dispensing mechanism while the machine operates. Maximum motor efficiency is then guaranteed over the whole working range.

A patented distribution system reduces the pressure drop of the working fluid through the inlet and outlet components of the compression chambers, that improve significantly the engine efficiency.
