Programming, software and visualisation. IT and telecommunications technology.
Optimal control of a biogas plant has a significant impact on its economic success. With the MT Energy Service control system, you can monitor and control your biogas plant down to the last detail.
In order to meet the increasing demands of the market, we are constantly developing our in-house control system for you. The V4 control system, which is used in industrial and foreign plants, grew out of the basic idea of the MT Energy V3 control system. The solid V3 functionalities have been structurally optimised to ensure a high degree of flexibility.
In addition, we support you with
- modernising and upgrading your plant computers with the latest operating systems (Windows 11)
- troubleshooting and installing routers and alarm devices
Intelligent add-on modules for your existing system:
visualisation, log centre and fault reporting centre.
- Reduction of peak loads
- Easy remote maintenance via PC and smartphone
- Specification of weekly schedules for your direct marketer
- Minimise the risk of control system failures
Container refurbishment
Substrates and biogas put strain on the containers in your biogas plant every day. Depending on the extent of the damage, it may be necessary to renew the coating or carry out comprehensive concrete renovation after several years.
When concrete wears out:
We restore your plant to top condition.
- Planning and execution: Renovation by trained specialists and coordination of specialist companies, e.g. for wall edge renovation.
- Modernisation of the substructure: Renewal of the beam layer or conversion to a tension belt substructure for improved load-bearing capacity.
- Renewal of other components such as agitator technology, container wall heating or enlargement of the gas storage volume by adjusting the air foil cover.
Container refurbishment not only serves to maintain the value and optimise your plant, but also ensures reliable plant operation!

Inflatable air dome
Double-shell air curtain covers consist of an outer weather protection film and an inner gas storage film. Depending on the specific load on the system and weather conditions, it may be necessary to replace the air curtain film cover. When replacing the film, we only use TRAS-compliant air-supported films, which enable you to easily comply with the requirements of TRAS 120 (Technical Rule for Occupational Safety).
TRAS120 compliant:
System solutions for film replacement and gas storage.
- Flexible gas storage films and dimensionally stable weather protection films for open round containers and special film clamping rails
- Replacement of the rail system with MT's Power Grip rail with additional mechanical safety device
- Customised film cuts, e.g. for height restrictions due to approval requirements
- Overpressure/underpressure protection, tailored to the respective container size
- Gas level monitoring with visual and sensory display
- Support air blowers in various versions, including redundant design

Gas detection
Plant safety and environmental protection require biogas plants to be gas-tight. However, detecting gas leaks is also worthwhile from an economic point of view. With a mobile measuring unit, the GasCam SG, we can locate biogas leaks reliably and at an early stage.
Early detection, targeted action.
Leak detection with the GasCam SG.
- Increased plant safety
- Higher gas yields
- Comprehensive test reports
- Documentation as part of the recurring inspection in accordance with § 16 BetrSchV
Safe operation begins with the right test
Pressure tests are a key component in the safe and legally compliant operation of biogas plants. They help to detect leaks at an early stage, prevent damage and meet legal requirements. As an experienced biogas service partner, we carry out the prescribed tests on substrate, leachate and gas pipes professionally.
Pressure testing of substrate and leachate pipes
These pipes are subject to the requirements of the German Industrial Safety Regulation (BetrSichV) and the AwSV (Ordinance on Installations for Handling Substances Hazardous to Water). A pressure test is required:
- Before initial commissioning of the plant
- After repairs before recommissioning
- Recurring, in accordance with legal requirements:
- Every 5 years for single-walled pipes without leak detection
- Every 10 years for double-walled pipes
Pressure testing of gas pipes
Gas pipes must be checked regularly for leaks in accordance with TRAS 120, the Hazardous Substances Ordinance (GefStoffV) and BetrSichV:
- Before initial commissioning
- After repairs or extensions
- Recurring every 12 years if permanently technically leak-proof system components are used
Requirements and common challenges
To ensure that we can carry out the pressure test efficiently, we check the local conditions in advance:
- Is a 1" female thread connection available or does it need to be retrofitted?
- Are shut-off valves at both ends of the pipe available and in working order?
- Is the connection point safely accessible, clean and supplied with sufficient water (for substrate pipes)?
Typical problems arise, for example, due to leaky or missing shut-off valves or missing connection options – especially in confined spaces such as under pump distributors.
