MAN Energy Solutions' service brand, MAN PrimeServ, and Makita Corporation have signed a three-year agreement to intensify their cooperation. The common goal of the partnership aims to offer customers worldwide the best possible service within SCR-HP (Selective Catalytic Reducation-High Pressure) systems from MAN Energy Solutions on two-stroke engines license-built by Makita Corporation.

MAN’s SCR-HP is used on MAN B&W two-stroke engines to meet IMO Tier III emission levels. The smallest and most compact of its kind, it has very low operating costs and is particularly fuel-efficient as the existing exhaust-gas temperature is sufficient and no additional burner is required.

Yu Makita, President of Makita Corporation, said: "We are pleased to take the next step in our cooperation with MAN Energy Solutions and intensify our collaboration with MAN PrimeServ for the benefit of our customers.”

Lukas Wengel, Head of Global Spare-Part Sales, MAN PrimeServ, said: “Following its successful class certification in 2020 and the increasing importance of Tier III environmental regulations, we find that more and more vessels are entering service with MAN Energy Solutions’ SCR-HP systems; indeed we have sold around 80 already. I am certain that this new spare-part, strategic cooperation between the MAN PrimeServ service network and Makita Corporation will be of great benefit to owners and operators of SCR-HP systems on Makita-produced engines.”

SCR-HP background

MAN Energy Solutions first introduced the SCR-HP concept in 2017. The development of the new system is based on MAN’s in-house competence with four-stroke engines, for which it can already reference more than 650,000 operating hours.

MAN’s SCR-HP is sold under the new PBST brand. It is available for two-stroke engines and reduces – through internal catalytic reaction – NO_x exhaust emissions to IMO Tier III limits. With specially developed honeycombs and honeycomb materials, as well as an integrated mixing unit, the overall size of the reactor has been drastically reduced compared to typical market designs and its medium-speed counterpart. The SCR-HP comes in six frame sizes, covering engines up to 25 MW with one reactor for the entire exhaust stream.

The system consists of the reactor – including mixing unit, urea injection lance, honeycombs and soot blowers – along with a module-based supply system, as well as the reactor’s control unit that communicates with the engine-control system.
