Realign your rotating equipment with your business goals

MAN PrimeServ offers both the consultancy and the technical services you need to achieve plant targets – whether you want to boost plant availability, efficiency, capacity, and the service life of your turbomachinery, or adapt it to new process parameters or advances in process technology. Business goals and market demands evolve over the long service life of your turbomachinery. Revamps and modifications enable you to realign the behavior of equipment with your goals. Updating machinery can offer solid financial advantages over new installations.

Revitalize your rotating equipment

Leverage our experience and expertise as a trusted OEM partner and machinery manufacturer to keep equipment up to date and maintain your competitive edge.

You may want to expand the production capacity of your plant, increase plant availability, or need to lower emissions and energy consumption.
At MAN PrimeServ, we take a holistic approach to updating equipment. For support with decision-making, consulting engineers analyze your process and conduct feasibility studies, highlighting your best options to achieve your plant targets. Modifications are based on your exact needs, replacing – or updating – only what’s unsuitable for your new process or goal. Revamp concepts are not limited to the core machine itself but consider ancillary systems, instruments, and controls as well.

We can also help plant operators move ahead with the digital transformation of their operations. Control system upgrades, enhanced machine monitoring and machine diagnostics are among the options available.
