About us – RMB/ENERGIE GmbH

Yanmar RMB AG


Founded in 2008 with an initial team of four in Saterland, Lower Saxony, RMB/ENERGIE GmbH has focused exclusively on the development and production of cogeneration units. In 2010 the compact “Silence Complete” cogeneration unit was ready for series production and was successfully brought to market. The “Silence Complete” is available in four performance classes ranging from 3.8 kW el to 7.2 kW el.


At the end of 2011, the neoTower® with its revolutionary space-saving design and an electrical capacity of 5.0, 7.2 and 11.0 kW was launched. Production of the “Silence Complete” was then discontinued.


In the spring of 2012, the performance range of the neoTower® was extended by two additional electrical capacity performance classes of 16.0 and 20.0 kW.


At the Hannover Messe trade fair in 2014, RMB/ENERGIE introduced the latest member of the neoTower® family – the neoTower® 50.0. A completely new software was also developed at the time for this cogeneration unit that makes CHP control, monitoring and operation even more efficient and simpler. Due to the increasing demand for the premium RMB/ENERGIE cogeneration units, the company was forced to relocate to a site that did justice to the company’s growth. The production facility footprint no longer met these needs.

In the summer of 2014, RMB/ENERGIE acquired a 1.1 hectare site with two halls on the main road in Saterland-Ramsloh. Another hall was erected and comprehensive conversion work (administration, production, state-of-the-art test benches) was carried out.


At the beginning of the year RMB/ENERGIE moved into the new production facilities in Ramsloh. The company celebrated their inauguration with a “New Year’s Reception 2015“. The 175 invited guests from the world of politics and industry included Franz-Josef Holzenkamp, Member of the Bundestag, and B.KWK Vice President Prof. Dr. Martin Maslaton.

The globally operating Yanmar Group acquired a majority holding in RMB AG. The goal is joint development of cogeneration units with Yanmar engines and continuing market leadership in the micro-CHP sector.

At the ISH Frankfurt 2015 the first exclusive cogeneration unit with a Yanmar engine was presented with the designation neoTower® Premium M+. This cogeneration unit is available with an electrical capacity of 25.0 kW and 30.0 kW.


Global innovation at the SHK: With the neoTower® LIVING, RMB/ENERGIE supplies the first cogeneration unit for family homes. With an electrical capacity of 2.0 kW it is ideal for use in homes accommodating one or two families.

RMB/ENERGIE currently has a workforce of 70.
