A spring starter uses potential energy stored in a spring wound up with a crank to start an engine without a battery or alternator. SESCO is the leading supplier of spring starters for use in engine-generators and hydraulic power packs, and on lifeboat engines, with the most common application being backup starting system on seagoing vessels.

Currently our range covers engines between a modest 0.5 litres (with the SPRS-01 starters) to over an impressive 18 litres (with the SPRS-06 starters). Our starters are flame-proof, waterproof and totally non-electric, making them ideal starting solutions in hazardous areas such as coal mines and oil rigs, where a single spark could result in a disaster.
The starter’s maintenance free nature provides a fail-safe solution in remote or harsh terrains, as either the primary or emergency starting device.
