HS – Hedemora Turbochargers History
• Hispano-Suiza was founded 1904 as a car
manufacturer that during WWI started to produce
aircraft engines and later aircraft.
• Turbomeca was founded 1938 and their first
demonstrator was a supercharger to the 1000hp
aircraft engine 12Y from Hispano-Suiza.
• Turbomeca started to produce small turbojets
1950, 1957 a turboprop and 1968 the bigger
Adour turbojet togheter with Rolls-Royce.
• Hispano-Suiza developed their first turbocharger
1958 and delivered many turbos in different sizes
until 2002, when their turbocharger
manufacturing business was acquired by
Turbomeca.
• In 2007 Turbomeca decided to only continue with
helicopter turbines, and in 2009 the turbocharger
business was aquired by Hedemora Diesel, as
part of Engenco’s vision to support and develop
the product .

Advantages with HS Turbocharger New Range
Compressor, shaft, and turbine balance separately
• Allows for fast response to changes in engine
loads.
• Weight on HS 5800 rotor assembly is only 30 kg
Low mass on rotor assembly
• Individual components can be replaces without
the need to rebalance assembly.
Hedemora Turbochargers
Feature Benefit
Compressor, shaft and turbine balanced Individual components can be replaced without the need to re
separately balance assembly.
Reduced maintenance time and cost.
Low Mass of Rotor Assembly Allows for fast response to changes in Engine Loads
Over 20 combinations of compressor cuts and Allows for efficient compressor matching with engine air
diffuser angles requirements whilst maintaining acceptable margin to the surge
limit
Inboard Bearing Configuration – Better access to Compressor and Turbine.
– Results in compact design saving space and weight.
– Improved design of Gas Inlet and air casings.
Lobe Type Plain Bearings – Low specific loading to better accept residual unbalanced
loads
– Long life expectancy >24000 hrs
– Low sensitivity to Vibration
– Optimised to accept lube oil at low pressure from the engine
Compact design Excellent for replacement of “original” turbo

HEDEMORA TURBOCHARGERS DEVELOPMENT PROJECT
HS7800 for Wärtsilä 18V32
Project started to develop a range turbocharger with higher
capacity to match larger engines.
First test is intended to be made on 18 cylinders Wärtsilä:
• Engine Type: Wärtsilä Vasa 18V32
• 18 cylinders
• 720 / 750 rpm
• 506.7 liters displacement
• Fuel MDO
• D model power [MW@rpm]: 6.66 @720 / 6.75 @750
• E model power: [MW@rpm] 7.29 @720 / 7.38 @750

Current HS5800 model is to small to match air flow requirement for
Wärtsilä Vasa 18V32D engine. Existing turbine size can be used for
matching but a larger compressor stage is needed.
- Design project is started at HS Turbocharger to develop a larger
compressor stage.
Design study showed current
limitations in flow capacity and a
new compressor stage was
developed/designed
18V32D
Compare HST to ABB VTR 354 and TPL 65 compressor maps.
With new design can a optimal matching be made for Wärtsilä Vasa 18V32D

The new HS7800 under testing in our in-house turbo During the testing/validation the new HS7800 was
test facility tested for different flows and pressures to create a
corrected compressor map.
Hedemora Turbochargers has recently
increased the turbocharger range with
new developed turbochargers HS6800
and HS7800.
HS7800 turbocharger is our new
designed turbocharger with increased
performance within the same frame size
used for HS5800 turbocharger.
Internally the compressor stage has
been changed to increase the air mass
flow. Bearing has been changed with
improved axial bearing design to
increase durability.
