MAN 175D SCR offers a very competitive solution for IMO Tier III application

MAN Energy Solutions reports that its highly compact MAN 175D SCR system recently completed its final Type Approval Test and has now been awarded IMO Tier III certification by all major classification societies.

Since the beginning of its development, the company has intensively tested the MAN 175D SCR system at its Frederikshavn, Denmark test center.

During this process, the SCR technology has built up more than 5,000 operating hours, both in Frederikshavn and aboard an operatiinge offshore vessel where the technology performed efficiently and reliably.

The SCR system was released for serial production in October 2018, and has already won its first order, which was booked last month. . “In order to deliver a very compact and cost-effective design, we have based the MAN 175D SCR system on our most cutting-edge technology,” says Daniel Struckmeier, Head of Exhaust Aftertreatment, MAN Energy Solutions. “A great strength is its flexible arrangement and compactness that optimize the space typically available in confined engine rooms.”

With an excellent power-to-weight ratio, airless operation and closed-loop NOx emission control, the MAN 175D SCR offers a very competitive solution for IMO Tier III applications. Due to its IMO NOx Scheme A certification, the system can be installed directly without further on-board confirmation tests.

The family concept of the MAN 175D SCR also allows the bundling of the full group of 175D engines into one parent-engine concept. As a result, the type approval covers not only the 12V175D in all its released applications, but also the 16V and 20V versions, which will be launched in the near future employing identical SCR components to those used in the 12V system.
