K2B: Knowledge 2 Boost

our double boost!

Optimum engine performance and compliance with the strictest emission limit values (e.g. IMO III) call for very high charging pressures and efficient exhaust-gas turbocharging. Solutions with combined exhaust-gas after-treatment or exhaust-gas recirculation offer even greater potential in view of increasing requirements.

We have developed the K2B two-stage turbocharging system for a maximum pressure ratio of 10:1 and a turbocharging efficiency of more than 75 percent to meet these demands.

Our K2B system provides you with a bespoke system solution based on your individual needs, including design integration, control strategy and after-sales service. This is our way of helping you achieve your engine output and emission targets.

Main fields of applications:

  • Power generation
  • Main propulsion engines
  • Auxiliary engines

Suitable for the following engine types:

  • Diesel engines
  • Heavy fuel oil engines (HFO)
  • Natural gas engines
  • Dual-fuel engines

Performance features of the K2B series

The K2B turbocharging system is characterised by the following performance features:

  • Turbocharger for a low-pressure and high-pressure stage in the engine output range from 1,500 kW to 5,000 kW per two-stage unit.
  • Maximum pressure ratio up to 10:1
  • Turbocharging efficiencies of more than 75 percent
  • High-pressure stage of the HSR series with a radial turbine
  • Low-pressure stage of the LPR series with a radial turbine or HPA series with an axial turbine
  • Bespoke system solutions for two-stage turbocharging combined with exhaust-gas after-treatment or exhaust-gas recirculation, for example
  • Compressor and turbine washing device, speed measurement, silencer and insulation available as accessories
  • Water cooling of the bearing casing for high-temperature applications on request

Your benefits:

  • System solutions for the integration of a two-stage turbocharging system that are perfectly matched to your engine
  • The highest power density for your engine
  • Greatly reduced fuel consumption
  • The lowest exhaust-gas emissions
  • Extended maintenance intervals and only short downtimes during servicing work
