Fermenter heating

Temporary heating or refrigeration for efficient biogas production

When it comes to the production of biogas, the process temperature inside the fermenter is a co-determining factor. When ambient temperatures are low, and during the heating up phase, it may prove necessary to introduce additional heat. In summer, there may be a need to cool the biogas to ensure that the optimum temperature range is not exceeded. Operators of biogas plants can use mobile energy plants to regulate the temperatures of substrate and/or biogas.

Mobile heating units can assist during the initial heating phase by providing an external supply of heat.

The mobile heating plant is connected directly to the existing heating system in the fermenter tank throughout the initial heating phase and supplies the requisite heating power in a direct manner. Without the need for modifications to existing plant components, it is possible to heat the substrate in the fermenter during the initial heating phase, until the fermentation process starts to run independently. If temperatures rise too high, Hotmobil is on hand with mobile refrigeration units to cool down the fermenter or the biogas.

Your advantages

The broad performance range of mobile heating plants from HOTMOBIL makes it possible to heat all fermenter sizes to the required temperature level during the startup period or when re-entering service. This saves the need to convert the engine on the biogas plant to run on different fuels. Mobile energy is also in service to safeguard the ongoing production of heat and power - to cover peak loads or during maintenance work on the CHP plant.

Practical solutions

Depending on the required temperature level, mobile heating units or heating containers are available in different performance sizes:
