+8 - 15 per cent
Higher gas yield
Optimised substrate preparation and active biomass circulation increase gas production – without the need for additional substrate.
up to - 30 %
Lower energy costs
Energy-efficient agitators and heat exchangers measurably reduce your plant’s internal power consumption.
> 20 years
Robust durability
Robustly manufactured components from Isny – designed for 24/7 operation in harsh biogas environments, with minimal maintenance requirements.
2 - 4 years
Quick payback
Thanks to higher yields and lower operating costs, our systems usually pay for themselves within 2 to 4 years.

Inefficient mixing costs performance and money
Inadequate mixing in the digester leads to fluctuating gas production, deposits and inefficient use of the substrate. Many agitation systems quickly reach their limits, particularly when dealing with high-fibre or viscous substrates. Reduce your biogas costs now .
Uneven distribution of the substrate
Declining biogas yield
High energy consumption
Malfunctions caused by deposits
Maximum mixing
High energy efficiency
Low-maintenance & durable
High operational reliability
Optimal mixing with the Varibull®paddle agitator
The Varibull®paddle agitator is a solution that has been tried and tested thousands of times for efficient mixing in fermenters, secondary fermenters and fermentation residue storage tanks – even with high dry matter content. Four large, specially arranged paddles ensure rapid and uniform mixing over a wide vertical range, whilst keeping energy consumption low.
Customer testimonials
Martin Hafner - 88367 Hohentengen, Baden-Württemberg
There is no need to adjust the settings on a regular basis. In 2006, I set up the paddle agitator once when it was first commissioned and haven’t had to adjust it since, for many years. The first overhaul of the agitator was not carried out until 2024.
Klaus Hölzl - 84419 Schwindegg, Bavaria
As a biogas producer , I am completely independent when it comes to the choice of substrate. I feed up to 80 per cent manure, a high proportion of which is horse manure. It is possible to feed up to 100 per cent grass or manure. Furthermore, theVaribull® biogas agitator mixesthe substrate more effectively.
Günter Nels - 54655 Wilsecker/RP
Thanks to its long service life and low maintenance requirements, the long-shaft agitator is the most cost-effective and hassle-free agitator option for biogas producers. I’ve only ever had to replace one arm on the PRW once.
Dirk Delfs - 24644 Timmaspe, Schleswig-Holstein
Compared with other paddle agitators, theVaribull® biogas agitation system is very energy-efficient. Frequency converters also have additional benefits for the paddles. Even at lower rotational speeds, above-average agitation results are achieved. The substrate is mixed evenly throughout the entire digester. Furthermore, the variable-frequency drive saves me electricity because the agitator only has to handle the load it actually requires.

Josef – Your point of contact
Tried and tested in thousands of biogas plants
The Varibull®is one of the most widely used paddle agitators in biogas plants and has proven its worth thousands of times over in practice.
- It is ideally suited for the digestion of renewable raw materials, in particular grass silage and manure,other substrates and slurry for biogas plants
- Energy-efficient thanks to large-surface-area mixing paddles – high electricity costs for the agitator are a thing of the past
- Effective mixing that preserves bacteria across the various substrate layers
- Reliable even with high dry matter content and long-fibre substrates
- Maintenance-free wall seal
- Maintenance-free, long-life plain bearinginside the pit
- No height adjustment required in the fermenter
- Biogas plant for slurry: copes well even with fluctuating fill levels, mixes the substrate more effectively and increases gas yield
- No other mechanical parts, such as chains, ropes or other suspension systems
- Low-maintenance agitator: simply install the paddle agitator , switch it on and let it stir – ‘good’
- the ideal fermenter agitatorfor long-fibre substrates
