MWM Biogas-Gasgenerator

Design Principles /Scope of Supply

Engine and flange-mounted alternator (SAE 1 housing) are connected via a torsionally resilient coupling and resiliently mounted to rigid, welded steel base frame.

* The base frame is installed on vibration dampers

* Standby heater for optional

* Lube oil pump for draining the oil sump for optional
