Advantages

Precision even under the most difficult conditions

Thanks to patented technologies, the BioBasic delivers precise measurement results even with high moisture contents or fluctuating process conditions – a clear advantage over standard solutions.

Maximum security for your system

With its safe, high-quality and robust design, as well as the additional ATEX-certified flame arresters and internal LEL monitoring in the device, the BioBasic reliably minimizes risks for the operation of your system.

Minimal calibration effort and low service costs

Thanks to the patented ZeroLock zero point correction and the long-term stable measurement technology, the BioBasic significantly reduces maintenance costs. In contrast to other measuring devices, regular calibrations using test gas are no longer necessary. This also noticeably reduces the running costs of your system.

Simple operability

With intuitive menu navigation on a resistive touch display, all information is available to you in plain text. The gas analyzer is plug & play and can be operated by anyone. The display is also available in a variety of languages.

FAQ

How does the BioBasic help to make my system more economical?

The BioBasic optimizes your biogas production by precisely monitoring the methane concentration (CH₄) and other gas components. With this data you can:

Maximize methane yield: Precisely coordinated processes ensure higher energy production, which leads to higher revenues.
Protect gas engines: Measuring hydrogen sulphide (H₂S) helps to prevent damage to expensive engines and catalytic converters. Repairs and breakdowns can cost several thousand euros a year - you can effectively minimize these risks.
Determine the optimum time to replace the activated charcoal filter: Using the measurement data, you can determine when the optimum time for replacement is and when the efficiency of the activated charcoal filter is decreasing. This allows you to use the activated charcoal filter as economically as possible - previous interval schedules are a thing of the past.

In addition, you can save costs for test gases with our devices: Unlike other measuring devices, the BioBasic does not require frequent calibrations with test gases.

Which gases can the BioBasic measure and why is this important?

The BioBasic measures the most important gas components for your biogas processes:

Methane (CH₄): Optimizes the energy yield of your system.
Hydrogen sulphide (H₂S): Prevents corrosion and damage to engines and catalytic converters.
Carbon dioxide (CO₂), oxygen (O₂) and hydrogen (H₂): Monitor the gas composition for stable processes and process safety. Too much oxygen, for example, can lead to a risk of explosion.
Others can also be monitored on request, e.g. ammonia (NH₃)

These measurements ensure compliance with legal requirements and prevent costly system problems.

How is the safety of my system ensured when using the BioBasic?

The BioBasic has ATEX-certified flame arresters that protect your system from explosion risks. It also has internal LEL monitoring in the housing.

The BioBasic offers additional protection for your system by reliably monitoring hydrogen sulphide (H₂S). H₂S is corrosive and can damage motors and system components. With the BioBasic, you can detect dangerous concentrations at an early stage and take protective measures in good time - such as changing the activated carbon filter - to ensure the longevity of your system.

How long does installation and commissioning take?

The BioBasic is a plug & play device. It is supplied completely pre-configured and is ready for immediate use. Simple operation via the touch panel makes commissioning even easier.

At what intervals is maintenance due?

Regular maintenance is important to ensure the functionality and precision of the devices. The standard maintenance interval for the BioBasic is one year. Reasons for the regular necessity of this are

Measurement accuracy: Deposits such as dust or impurities in the gas lines and measuring cells can lead to deviations in the measurement results (drift effect). Annual cleaning and calibration prevents these inaccuracies and ensures that the measured values remain reliable.
Wear inspection: Components that run under high loads throughout the year are subject to natural wear and tear. Regular servicing enables these components to be checked and replaced in good time to prevent device failures.
Software updates: Software updates must be installed every 1-2 years so that the device benefits from the latest developments, improvements and innovations and to ensure compatibility and security.
Filter change: Filters that become contaminated over time must be changed regularly to ensure the proper functioning of the system.

How high are the maintenance costs?

The maintenance costs of the BioBasic are extremely low because:

An automatic zero point correction eliminates the need for frequent calibrations with test gases.
wearing parts such as sensors have a long service life.
The robust construction compensates for contamination in the measuring cell.

Compared to conventional appliances, you save significantly on annual maintenance costs.

Is the BioBasic also suitable for small biogas plants?

The BioBasic is suitable for both large industrial plants and smaller biogas plants. With up to five sample gas channels, the device is flexibly adaptable and covers all relevant requirements - whether for power generation in the CHP or for upgrading to biomethane.

Can I use the BioBasic at high humidity levels?

Yes, the BioBasic is equipped with an integrated condensate separator that can cope with high levels of moisture in the biogas. This ensures that measurement accuracy is maintained even under difficult conditions.

The automatic condensate drain protects the appliance from flooding and damage caused by moisture.

How accurate are the measurements?

The BioBasic achieves a measurement accuracy of ±3% and a long-term drift of less than 3% per year. This precision is crucial for stable process control and reliable long-term data.

What operating costs do I need to plan for?

The BioBasic is extremely energy-efficient with an electrical output of around 207 VA. Combined with the low maintenance requirements and the savings in test gas costs, this results in low operating costs, making it an extremely economical solution.

What happens in the event of a technical problem?

The device shows errors and faults in plain text on the touch display so that you can react quickly. If required, our service is available by phone 365 days a year and on site. Failures are extremely rare thanks to the robust and high-quality design.
