M-Line – Modular line for Small Hydro solutions at Voith

Small Hydro is nearly endless, ecologically and commercially sustainable

    Complete water-to-wire solutions designed and manufactured by Voith.

    There is tremendous potential in small hydro sites – thousands of existing low-head hydro sites and underutilized resources waiting for retrofitting or upgrades. Energy recovery, as well as new run-of-river sites, provide outstanding potential. The M-Line product line represents comprehensive solutions for the sustainable generation of electricity from these resources. Standardized products for individual applications offer an attractive blend of high performance, quality and cost efficiency.

    Benefits of Small Hydro

    • Economically viable
    • Available globally with benefits for remote communities
    • Low environmental footprint and risks
    • Easy to operate and to service
    • High-quality energy resource

      StreamDiver – Low head hydropower applications

      The StreamDiver provides an industry-wide unique design which allows a simplification of the entire power house design. The StreamDiver product family covers many applications. Lubrication and cooling water systems are not required, actuation systems for control and start-up are reduced to a minimum. A flexible and modular integration into the civil infrastructure is possible due to the modular line as all assemblies are modularized and standardized. Ease of installation and maintenance allow cost savings throughout the project phase.
