Case Study: Electric starter System
Challenge
An engineering integrator needed to replace the traditional hydraulic start system on gas turbine generators with a more compact efficient solution. Traditional pneumatic/hydraulic starter systems are complex and demand comprehensive maintenance due to the presence of filters, valves, solenoids, reservoirs, pumps/compressors, gauges, heat exchangers, piping/hoses and fittings.
