HEF 109 starter for high power requirements
With a nominal power output of up to 10 kW (24 V), HEF 109 starters are used to start diesel engines with a displacement of up to 30 l and under common cold start requirements. Their robust, compact and modular design makes them a great solution. The starter systems are designed for up to 14 000 hours of operation in stationary machines and other off-highway applications (approximately 800 000 km on highway). They are characterized by their high performance density and great cold start capability. On top of that, their weight is up to 50 % lighter compared to direct starters of the same performance class.
HEP 109 parallel-starter systems for large engines
Parallel starter systems (HEP 109), which consist of two or three synchronized HEP 109 starters, increase widely the scope of application. They are suitable for diesel engines with up to 90 l and gasoline engines with up to 180 l of displacement.
