Maschinenfabrik Reinhausen

What Maschinenfabrik Reinhausen does

Maschinenfabrik Reinhausen (legal entity Reinhausen GmbH, recently rebranded from Maschinenfabrik Reinhausen GmbH) is a German power engineering company headquartered in Regensburg and privately held by the founding Scheubeck family since its incorporation by Andreas Scheubeck in 1901. The company is the global market leader in on-load tap-changer (OLTC) technology for power transformers, with stated coverage of approximately 50% of electrical energy transported worldwide regulated using MR solutions. Operations span 57 locations across 28 countries with 5,001–10,000 employees, and the firm holds roughly 1,500 active patents globally.

The product portfolio is anchored on the VACUTAP® vacuum on-load tap-changer family (VI, VBO®, VRL®, VM®), complemented by TAPCON® voltage regulation controls (including the 230 and new ISM® hardware platform), the ETOS® transformer automation system, and the TESSA® APM asset performance management software suite. MR also offers the VRDT voltage regulation distribution transformer for renewable-heavy distribution grids, MSCDN grid-stabilization technology, and high-voltage testing equipment via its HIGHVOLT Prüftechnik subsidiary, plus monitoring instruments from Messko. Revenue is generated primarily through hardware sales of OLTCs and transformer components, with a growing recurring software/services layer (TESSA APM, myReinhausen platform, 24/7 service, MRcademy training). The go-to-market is enterprise field sales executed through wholly-owned regional subsidiaries in markets such as the US, China, India, Korea, Japan, Brazil, and across Europe, supplemented by the ReinhausenShop e-commerce portal and digital customer platform.

Customer segments are horizontal across the power value chain: transformer OEMs that integrate MR components, public transmission and distribution utilities, industrial grid operators with private networks, and energy companies navigating the energy transition. Strategic positioning emphasizes enabling stable grid operation amid renewable integration, aging-asset retrofit/digitalization, and lifecycle extension through condition-based monitoring — a value proposition reinforced by a 16-week committed OLTC delivery time, 1,500 patents, and the "Made by Reinhausen" quality umbrella applied uniformly across all global production sites.
