912 W
The underground mining engine.
47 - 93 hp at 2500 rpm
These are the characteristics of the 912W:
Air-cooled
four stroke
3-, 4-, 5- and 6- cylinder in-line engines.
DEUTZ-two-stage combustion.
PTOs via gear, flywheel and v-belt pulley.
Extremely compact design.
High torque at low speed.
Modular system with single cylinder arrangement and high degree of parts commonality.
Customized component system with many different peripheral parts.
Your benefits:
Fast response to load changes.
Minimal environmental impact. All engines are certificated acc. to MSHA.
Low operating costs thanks to lower fuel consumption, low specific ventilation
requirements and long maintenance intervals with reduced maintenance
requirements.
Compact design saves installation space and thus construction costs.
Easy-to-install unit (engine with integrated cooling system).
