To keep production costs at a low level and avoid sources of errors, the plants are produced in series in standard plant sizes. The series production allows short delivery times. Due to the use of proven components, a long service life can be ensured.
The Zeven model
The aim is to keep the energy consumption during the upgrading and the transport of the biomethane as low as possible. Thanks to the combination of CHP and upgrading an overall efficiency of 80% can be reached. The energy is produced where it is consumed.
Due to the small plant size, it can also be integrated into small grids with low pressure. The costs for the compression are minimal. For energy supply with focus on the regional added value the Zeven model is the right size for a municipality of 5,000 inhabitants and above.
Key figures:
- Flow rate in raw gas: 250 Nm³
- Overall size of the biogas plant while self-sufficient energy supply: 600 - 900 kWel
- Provision of energy for single family houses: 420
500 Nm³
The 500 system marks the entry into large plant types as the first plant in which the thermal process takes place in two container units.
Key figures:
