REO

What REO does

REO (REO (UK) Ltd / REO AG) is a family-run German industrial manufacturer founded in 1925 in Berlin and headquartered in Solingen, with a UK subsidiary in Craven Arms. The company develops and produces inductive, resistive, and electronic components — including chokes, EMC filters, transformers, current transformers, resistors, power controllers, thyristor controllers, and vibratory conveyor control systems — organized under sub-brands REOVIB, REOTRON, REOhm, REOMED, REONET, and REOWAVE. All products are manufactured in Germany and shipped to a global customer base across at least ten vertical markets: drive technology, railway, e-mobility, power electronics, medical, testing and laboratory, marine and offshore, vibratory conveyor, defence, and special applications. Key proprietary technologies include EDGE Winding (enabling up to 25% power dissipation reduction and 10% weight savings, well-suited to SiC and GaN semiconductors), the exclusive MPS Moisture Protection System, liquid cooling (reducing construction size up to 70-80%), and the REONET IIoT platform providing OPC-UA connectivity.

The business operates on a B2B, quote-based model with no public pricing; customers engage via sales specialists, a website product finder, and direct consultation, with multi-year contracts typical for customized developments. REO emphasizes tailored solutions across a spectrum from standard products to fully customized developments, supported by in-house 3D-FEM simulation, EMC and thermal analysis capabilities, and certifications including DIN EN ISO 9001, IEC 60310, EN 15085 (railway welding), IEC 60601-1 (medical electrical equipment), and UL. The company maintains international subsidiaries in Europe, North America, Asia and the Middle East, while consolidating manufacturing at German sites.

Revenue is not publicly disclosed. Based on the 11-50 UK headcount, German Mittelstand scale, multi-vertical exposure, and 100-year operating history, group revenue is most likely in the $50M-$100M range, though confidence is low due to absence of audited disclosures. Growth trajectory is best characterized as moderate, supported by recent product launches (REOVIB 2.0 in 2024, REOMED Edition 3.2 certification), active expansion into e-mobility and defence verticals, and continued IIoT platform investment, against a backdrop of stable family ownership and no external funding events.

Core offering

REO develops and manufactures inductive, resistive, and electronic components including chokes, filters, transformers, current transformers, electrical test equipment, and resistors (branded as REOhm, REOVIB, REOTRON, REOMED, REOWAVE, and REONET). The company offers standard products, modified products, and fully customised solutions built at German production sites and sold directly to industrial buyers worldwide.

Product overview

REO is a family-run company (founded 1925 in Berlin) specializing in inductive, resistive and electronic components as well as complete solutions. The product portfolio operates as a multi-brand ecosystem centered on several key sub-brands: REOVIB (vibratory conveyor technology including frequency converters, phase angle controllers, AC magnets, and the flagship MFS 368 controller), REOTRON (power electronics including thyristor controllers and power supplies), REOhm (resistors including braking, discharge, and liquid-cooled variants), REOMED (medical isolation transformers), and REONET (IIoT connectivity software). The core product categories span eight main areas: Vibratory Conveyor Technology (REOVIB products), Power Controllers & Supplies (REOTRON products), Chokes (mains, harmonic, DC link, dv/dt, motor, sinusoidal, liquid-cooled, and train chokes), Filters (single/three-phase line, DC, dv/dt, and high current filters), Transformers (toroidal, medical isolation, variable, and railway), Current Transformers (active and passive), Electrical Test Technology (REOLINE power supplies, load units, voltage stabilisers), and Resistors (REOhm braking, charge/discharge, liquid-cooled, damping, UL, and high voltage). REO emphasizes custom development capabilities, liquid cooling technology, EDGE winding innovation, and products designed for demanding environments including railway, marine, medical, and e-mobility applications. All products are manufactured at German sites with focus on durability, low maintenance, and high quality standards.
