Retrofits and Upgrades for Feed-In Technology in Biogas Plants
Targeted improvements to existing systems—without a complete system overhaul
Retrofit measures help to specifically optimize individual weak points and adapt existing installation technology to new requirements.
Common Reasons for the Need for Optimization
Wear and tear on individual components
Inefficient Processes
Uncoordinated systems
Problems with Substrate Changes
Increasing maintenance costs

FAQ
Frequently Asked Questions About Retrofit Measures.
What exactly does a retrofit of a biogas plant involve?
During a retrofit, outdated or heavily worn individual components—such as screw conveyors, drives, or dosing systems—are specifically replaced with modern, higher-performance components. Unlike a complete overhaul, the basic structure of the system remains intact.
When does it make sense to upgrade or retrofit the feeding system?
Retrofitting is a good option when individual system components become increasingly prone to malfunctions, maintenance costs rise disproportionately, or a change in substrate (e.g., to a fibrous material) requires the existing technology to be adapted.
Which components can be retrofitted in existing systems?
Typical retrofit measures include installing more wear-resistant augers, upgrading to more energy-efficient drives, or optimizing the disintegration technology to prevent clogging when processing difficult substrates. These solutions can often be easily integrated into existing third-party systems.
How long does the system shutdown last during a retrofit?
Since a retrofit involves only the targeted replacement or modernization of specific, isolated areas in need of improvement, downtime is significantly shorter than with comprehensive renovations. These upgrades can often be integrated into regular maintenance windows that are already scheduled.
