In the area of landfill gas we offer maintenance and service for landfill gas CHPs as well as for booster stations and flare plants.

The maintenance for CHPs is carried out by TDL Energie for MAN and MWM/Caterpillar motors for biogas and landfill gas. This includes not only the maintenance of the motor and generator unit with the regularly scheduled maintenance and repair, such as replacement of cylinder heads, but also maintenance of surrounding equipment of the CHP like gas ramp, emergency cooling equipment and technical ventilation.

For booster and flare systems TDL Energie carries out oil change at the booster, cleaning and if necessary replacement of the deflagration flame arresters.

The operational optimization of the gas collection system, inspection and adjustment of the gas wells and the gas collection units can be undertaken in the course of maintenance visits at the individual local sites by our service engineers. Plant components such as shutoff valves and control valves, measuring lines and expansion joints will be checked and replaced if needed according to the customer’s wishes.

According to the permits of landfill operators FID inspections on site are required, i.e. the measuring of near-surface methane concentrations using a portable flame ionization detector.
