FARMATIC - Conventional Digesters and Combined Storages

It is our business philosophy to supply our customers with a complete hands-free digester solution with a consistently high quality all over the world. Our digesters are supplied including a double membrane gas holder and FARMATIC`s electrical stirrers

FARMATIC digester and biogas storage solutions are supplied in standard sizes or in custom designs according to client preferences.

By combining a digester chamber with an integrated gas holder, conventional digester systems are a cost-effective alternative for smaller digesters up to 2,400 m³ and for substrates that can easily be mixed. FARMATIC uses this tank design as post-digester and combined gas and digestate storage in larger turnkey projects.
