Hochreiter biogas plants have more than 25 years the worldwide reputation of versatility, functionality and reliability. The device has undergone years of practical development but still retains a certain simplicity.

Our fermenters are of the proven conception „ring in ring“ built of waterproof reinforced concrete. The membrane gasholder can be installed upon the inner ring of the fermenter or upon the storage tank.

Feeding of the solid stock is provided by the Fliegl PolyPro dosing unit with extremely low power consumption. The patented Mississippi agitators ensures absolutely sufficient stirring performance at high dry matter levels. Mixing is further ensured through vertical paddle agitator and auxiliary side agitator.

Between outer and inner ring of the fermenter the substrate is transported by overflow, without any need for pumping. On the same principle works the outflow of digestate into the storage tank. Pumping of material between any parts of the biogas plant is also enabled through a central pump.

The fermenter is heated by the system of stainless steel pipes attached to the inner walls. Conical or dome-shaped membrane gasholder can be installed upon the inner ring of the fermenter or upon the storage tank. The time proven Deutz-MWM cogeneration (CHP) unit ensure high electrical efficiency. The biogas plant is equipped with fully automatic control including visualization and remote access via internet.
