Agitators for biogas technology
WE MAKE STIRRING BETTER !
The agitator is the most important component in biogas technology. It is the “heart” of an anerobic digestion plant.
Whether it is for the digester, secondary digester or the end storage tank – the right mixing technology must be able to deal with an extensive range of feedstocks. It must be able to stir fibre rich feedstocks with a high DM content. It must also be able to cope with waste from agriculture, general refuse and
industry.Whether you are constructing a new plant or repowering an existing one – Peters will plan the mixing system with you, so that it is perfectly suited to your needs and the demands of your feedstock.
Dosing System
ECO-DOS R
-
The digester feed has a key role to play in biogas plant performance. Our „ECO-DOS R“ solids feeder is available in four modular versions.
Thanks to its corrosion and acid-resistant interior lining it is extremely durable. It can operate forwards and backwards and is suitable for side or rear loading. It can be interfaced with the plant central control system via a PLC control. The „ECO-DOS R“ is also available with a weighing device.
This feeder has very low energy requirements.

Paddel Mixer
Paddle Mixer EXCENTRO V
-
THE VERTICAL EXCENTRO
The defining characteristic of Paddle mixers is that they mix slowly and evenly.
This means that the bacteria in the mix is constantly fed, thus promoting the undisturbed anerobic breakdown of the biomass.
Paddle mixers are especially suited to challenging feedstocks and those with a high concentration of dry matter.
The paddles ensure that the digestate is mixed thoroughly, thus fully homogenising any floating or sinking layers. Our EXCENTRO V paddle mixer has already proven its high level of efficiency in numerous plants.

Paddle mixer EXCENTRO S
-
THE DIAGONAL EXCENTRO
Based on this sophisticated and highly reliable technology Peters have developed the EXCENTRO S paddle stirrer.
Just like its partner system, its special advantage is that all of the maintenance and replacement work on the EXCENTRO S can be carried out without emptying the digester.
Now this even applies to digesters with flexible gas storage instead of concrete covers. For operators this means the minimum amount of downtime for the plant.
The EXCENTRO S also has a gear reducer motor with an output of between 7.5 and 15 kW. High quality and robust materials guarantee smooth low-maintenance operation.The full diameter of the system is 3 m and the length is between 5 and 10 m. The EXCENTRO S not only ensures optimum efficiency in new plants, it can also be installed to upgrade existing plants.

The Methabolix
Based on our decades of experience in the manufacture of agitators for agriculture and biogas plants, we have developed our "Methabolix" power package.
It can be installed laterally into the concrete wall, from above through the concrete ceiling or over the roof frame "Methabox". The installation can also be carried out with the tank filled.

Service-Methabox
Mixers for Air-Supported Roofs
-
The Methabox® system is a built-in option for flexible gas storage, such as air-supported roofs and has been specially developed for flexible gas membranes.
Air-supported or foil roofs are often used as flexible biogas storage and gastight silo covers for biogas plants. These roofs are usually made of a PE film and an outer weather protection film made of PVC. The new Methabox system from Peters Mixer is easy to install into these air-supported roofs on biogas plants. The stainless steel frame is shaped so that the film can fit around it perfectly. At the same time the tarp between the two sheets is pulled taut, both for the double and single membranes. Thanks to the curves, stress points are avoided.
As with all stirring systems from Peters, maintenance and repairs can be carried out easily as the agitator (EXCENTRO) can be removed without draining the digester. The Methabox system is not just an option for new plants, but also for the expansion of existing plants.
