BioGas produced by wastewater systems is a clean and efficient energy source that can be used to power engines in place of gasoline. Depending on the biogas it can contain raw material that needs to be filtered prior to the engine and this is where NISSEN Power Modules (NPM) come into play. They are based on MAN’s modern and robust gas engines, but are customized CHP-units designed and built in the NISSEN workshop. They supply these robust filters for gas cleaning in several sizes, depending on the amount of gas to be cleaned. Maximum gas utilization and protection of the power plant is where NISSEN’s design and expertise shine. NISSEN can provide a system that will meet any biogas engine need.
