Product Overview
Low calorific gas high temperature combustion is necessary on more and more sites due to increased aftercare requirements. With a suction pressure regulation the landfill is stabilised and the gas concentrations are monitored continuously by means of gas analysis.
Hofstettergas control systems have been successfully implemented on landfill sites for more than 35 years. With HOFG-4S'- Lowcal, the existing gas collection system can continue to be used. And thanks to the high temperature combustion, the emissions values comply with the regulations in force.
