FAQs
Answers regarding high-torque electric, pneumatic, and mechanical spring starters.
A: We offer three main starting technologies: high-torque electric (for applications such as data center generators, where a single starter can replace a dual-starter setup), mechanical spring (a backup starting method, independent of electrical power, for firefighting, emergency rescue and marine EDGs), and pneumatic (spark-free, high-frequency starting for oil & gas and mining). Our engineering team can help you select the most suitable option for your site conditions.
A: Yes, in many applications. Our QD21129 (11 kW) is designed with high initial breakaway torque for large-displacement diesel engines. A single unit can replace a traditional parallel twin-starter arrangement with fewer components to procure and maintain.
A: The spring starter stores mechanical energy when the winding handle is turned by hand. Pushing the trip lever releases the stored energy to crank the engine, with no batteries, compressed air or electric solenoids involved. It requires no battery replacement and is designed for low maintenance.
A: Yes. Mechanical spring starters are driven mechanically and produce no electrical sparks during starting. Our spring starters also use a pre-engaged pinion design, in which the pinion fully meshes with the flywheel ring gear before cranking torque is applied. Requirements for hazardous areas vary by site, so please contact us with your operating conditions.
A: In many cases, replacing an electric starter with a spring starter requires no flywheel housing modification. Fitting a spring starter alongside an electric starter requires a twin-starter flywheel housing; if the housing has only one mounting hole, a custom dual-lug flywheel housing is required. Please contact us with your engine model and flywheel housing details.
