Our smallest turbocharger is a light weight model even though its water cooled.
A bigger version of HS 430 with higher mass flow and slightly higher pressure ratio.
Advanced design of aerodynamic parts greatly improves the pressure ratio & efficiency. Improved bearings doubles the normal operational time without maintenance. The bearing and exhaust housing is separated by heat shields and can thereby be only air cooled.
A bigger version of the HS 4800 with higher mass flow.
Modified version of the HS 7800 that suits slightly smaller engines and is now tested on the first locomotive.
A newly developed bigger turbo designed for engines with air flow of up to 8,5 kg/s and up to 4200kW, but still only slightly bigger than HS 5800.
