RMB/ENERGIE

What RMB/ENERGIE does

RMB/ENERGIE GmbH is a German manufacturer of decentralized combined heat and power (CHP) units marketed under the neoTower® brand, headquartered in Saterland-Ramsloh, Lower Saxony. Founded in 2008 with four employees, the company has built an 18-model neoTower product range spanning 2.0 to 71.0 kW electrical output, all built around industrial YANMAR or MAN gas engines with integrated condensing-boiler technology achieving up to 109.5% total efficiency, continuous power modulation down to 50%, and multi-fuel operation across natural gas, LPG, biogas, sewage gas, and hydrogen blends. The hardware is paired with a LiFePo4-based Stromspeicher (BSS/BOS) storage system featuring Blackout-Start capability, plug-and-play Energiecontainer outdoor solutions, hybrid neoTower + heat pump configurations for GEG 65% renewable compliance, and the RMB/REPORT cloud monitoring platform for remote diagnostics.

The company generates revenue primarily through one-time hardware sales of neoTower units plus a meaningful recurring stream from multi-year maintenance and full-service contracts (Basiswartungsvertrag, Vollwartung 40/60/80, and Vollwartung+ with general overhaul, with terms up to 15 years and up to 80,000 operating hours). Complementary add-ons — battery storage, energy containers, Bi-Fuel kits, exhaust systems, financing through MMVfinrate, and subsidy facilitation through BEN-Tec — represent further revenue lines. Go-to-market is sales-led via direct field representatives, technical sales engineers, regional reps in Germany, Italy, the Czech Republic (IBG Česko), and the UK (Fleetsolve), supplemented by trade fair presence (ISH Frankfurt, GET Nord, SHK), BIM/tender-text downloads for installers, and — since September 2025 — a unified Yanmar-Group sales channel through sister company TEDOM Service GmbH that combines the 4.0 kW–4.5 MW CHP range. Customer segments span agriculture and biogas operators, residential multi-family and social housing (e.g., GEWOBA Emden), hotels, hospitals and senior living (e.g., AWO Emden), industrial and manufacturing users (e.g., Oxytabs), and education/research (TUM CoSES, HWK Dresden).

RMB/ENERGIE operates as a majority-owned subsidiary of Japan's Yanmar Group following the 2015 acquisition of RMB AG, and functions as the Yanmar Group's lower-to-mid-range micro-CHP development, production, and service hub. With a reported 80+ employees and stated annual unit output above 500 globally, plus DVGW, SVGW, and DIN EN ISO 9001 certifications, the company is positioned as a niche specialist inside a larger conglomerate — a positioning reinforced by the 2025 leadership restructuring and sales-channel consolidation that aligns commercial execution with TEDOM while preserving RMB/ENERGIE's role as the small-to-mid CHP manufacturing and engineering center.

Revenue model

1. BHKW Hardware Sales (neoTower Units): One-time sale of neoTower Blockheizkraftwerk units across 18 models from 2.0 to 71.0 kWel. Revenue generated from initial equipment sale including installation, commissioning, and handover. Multiple configuration variants (Standard, HT/Hochtemperatur, BW/Brennwert) and fuel types (natural gas, LPG, biogas) affect final pricing.
2. Maintenance and Service Contracts: Recurring revenue from maintenance contracts including Basiswartungsvertrag (10-year term, basic maintenance + remote monitoring), Vollwartung 40/60/80 (up to 80,000 operating hours or 10/15 years), and Vollwartung+ (with general overhaul, 10 or 15 years). Contracts include scheduled maintenance, remote monitoring, and optional wear parts coverage.
3. Accessories, Stromspeicher, and Energy Containers: Sales of complementary products including LiFePo4 battery storage systems (BSS/BOS), energy containers (pre-configured outdoor solutions with BHKW, storage, heat pump, buffer storage, wallbox), and accessories such as Bi-Fuel kits, exhaust systems, and sound insulation components.
4. Förder- und Betreiberservice (Subsidy Support): Through partnership with BEN-Tec GmbH, RMB/ENERGIE facilitates customer access to government subsidies under KWKG (Cogeneration Act), BAFA funding, and regional programs. This service supports sales by making investments more financially attractive through subsidy capture.
