Bowman’s ETC Technology
Each ETC system comprises of a turbocharger, turbo generator and power electronics unit. These components work together to either increase the efficiency of your genset or increase the power output.
Which ETC system is right for me?
We have three core ETC systems and can create bespoke high-speed electrical machines to suit your requirements. A summary of these systems, along with links to component specifications is below. To find out more, contact us.
