Yanmar Co., Ltd.

YANMAR announces the acquisition of a majority stake in RMB AG, German manufacturer of micro cogeneration systems.

As a leading supplier of innovative energy solutions, YANMAR aims to assume market leadership in the micro cogeneration unit sector, and intends to launch the neoTower® on a global basis. In addition to the European home market of the high-efficiency cogeneration unit, the North American market also offers tremendous potential.

"With YANMAR as our strategic partner, we are systematically continuing what we began in 2014 with the very successful development of a new generation of cogeneration units – the Premium M+ performance class; production of a family of premium cogeneration units based on the YANMAR industrial engines," explains Jens Brake, CEO of RMB. RMB operates on a European basis as a manufacturer and supplier of premium cogeneration units. With the neoTower®, the company has developed a micro cogeneration unit that sets new standards with regard to compact design, smooth running, efficiency and user friendliness. With the neoTower® 30.0 for YANMAR, a specialist in the very latest engine technology, RMB developed a premium cogeneration unit that is specifically designed for YANMAR’s robust gas engines. From now on, YANMAR will be exclusively supplying RMB with a number of additional engines in various performance classes for a wide range of innovative products.

"The most important factor was the technology," comments Akihiro Nishimura, General Manager of YANMAR Energy System Business Unit. "From our viewpoint, with its neoTower®, RMB has the best product on the market. The energy efficiency is very high and the development speed very fast. During our cooperation in development, we had the idea to come together."

With YANMAR, RMB has gained a strategic partner that will allow the company access to international markets. RMB will continue its independent operations within the YANMAR Group. As a strong partner, YANMAR will make its sales and service networks available, therefore creating valuable synergies. RMB will make use of its technological head start in the cogeneration unit field combined with innovative YANMAR engines for international market success. The products will continue to be marketed under the name neoTower®, and are aimed at owners of residential properties, small and medium enterprises, hotels and industrial applications. Henning Brake, CEO of RMB, summed up as follows: "The association of both companies lends us more strength in international markets. We are starting out on a journey together to a new world of efficient energy utilization."

Currently, YANMAR America’s Energy Systems division offers 5 kW (CP5WN) and 10 kW (CP10WN) EPA-compliant micro cogeneration units for the North American market. To learn more about these units and other Energy Systems products, please visit
