The key factor in the gasification process is achieving a high temperature (800-1200°C), which prevents formation of damaging tar compounds. This results in tar compounds cracking into lighter fractions, which do not cause engine problems. Wood gas that is run through the GASEK purification line is completely colourless and odourless, and its combustion causes no hazardous particle emissions.

Clean wood gas provides a possibility for manufacturing efficient, maintenance-friendly and long-serving power plant solutions. A number of international patents have been obtained for the GASEK gasification technology.
