REHART

What REHART does

REHART GmbH is a privately held German industrial-equipment manufacturer headquartered in Ehingen, Germany, founded in 1980, operating through sub-brands Schreiber Technology (wastewater, since 1975), Petersen Service (ceramics machinery), and REHARTPOWER (hydropower). The company designs, manufactures, refurbishes, and services mechanical-engineering equipment across five verticals: municipal and industrial wastewater technology, hydropower, recycling and biogas plants, hydraulic steel structures, and coarse and fine ceramics processing equipment. Core proprietary technologies include nanoseal ceramic composites, REHART Composite Armor Plates (RVP), polyurethane coatings, LEVELTRONIC precision fill-level measurement, and the proprietary PK-Designer CAD software for extrusion-head design.

The business is organized as a platform-plus-modules model sharing metalworking, wear-protection, and after-sales capabilities across diverse industrial applications. Products span custom-built machines (vacuum extruders, double-shaft mixers, extrusion heads, hydropower components, hydraulic steel structures) and standardized wear-protection components, with associated spare-parts supply committed for decades after original delivery. Revenue is generated through custom-quotation, project-based capital-equipment sales, recurring spare-parts revenue from the long-tail installed base, refurbishment services for screw pumps/augers/pumps/bearings, and ongoing service contracts (consulting, installation, support contracts, optimization). Pricing is quotation-based on customer specifications, industry requirements, and project scope, with multi-year contract cadences on the service side.

Go-to-market is sales-led B2B with technical consultation, targeting municipal authorities, industrial facilities, ceramics producers, hydropower operators, recycling/biogas plants, and agricultural technology customers across Germany and 30+ countries in Europe, the Middle East, and North Africa. Channels combine direct sales with phone/email/contact-form engagement, industry-specific PDF inquiry forms (including a German-only "Serviceformular Ziegel" for the brick industry), the Morte cooperation partnership for extrusion dies in D/A/CH plus Romania and Poland, corporate-website content in German and English, and social/newsletter presence. The customer base spans private-sector enterprise and public-sector municipal procurement with no publicly disclosed revenue, headcount disclosure limited to a 51-100 range, and managing partner Philipp Schülein identified as the named executive.
