- Model Sparky - Compact Degassing Unit



The HOFGAS- Sparky compact degassing unit is used for household waste landfills without gas utilisation.


HOFGAS- Efficiency high temperature flare provides controlled combustion. Landfill gas is burned at temperatures between 1’000 and 1’200°C and a defined residence time. This ensures compliance with the emission regulations.

All components are mounted onto a robust galvanised steel skid. The control elements are integrated in a weather proof control cabinet directly fixed onto the supporting construction. The PLCsystem ensures a reliable operation of the plant.

Using a simple crane, the plant can be set up on a prepared site in very short time. The HOFGAS- Sparky complete extraction and flaring unit is immediately ready for operation.
