FAQs
Answers regarding high-power, high-torque electric, pneumatic, and mechanical spring motors.
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 select the best fit based on your available site utilities.
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, which can reduce procurement cost, save engine bay space, and simplify the wiring of the starting system.
A: The spring starter stores mechanical potential energy through manual cranking with a winding handle. Pulling the trip lever releases the stored energy to crank the engine, without batteries, air pressure or electric solenoids. It requires no battery replacement and is designed for low maintenance, with reliable starting in both high and low temperature environments.
A: Yes. Both our pneumatic starters and mechanical spring starters are built on mechanical drive principles, with no electrical components at the starter, so starting does not introduce an electrical spark source. Our pneumatic starters also use a pre-engaged pinion design, where the pinion fully meshes with the flywheel before cranking torque is applied, reducing gear-tooth impact during starting.
A: Yes. We support standard SAE flange interfaces (e.g. SAE 1, SAE 2, SAE 3) and provide custom flange engineering for non-standard or older engine platforms. Please contact us with your engine model and flywheel housing details for a custom fit.
