What EPA does

EPA GmbH is a German industrial specialist founded in 1988 and headquartered in Bruchköbel, Germany, operating across three interconnected technology domains: drive technology, EMC (electromagnetic compatibility) technology, and leakage current technology. The company positions itself as a market leader in leakage current technology and serves industrial B2B customers across virtually all industrial sectors that use variable frequency drives, motors, and power electronics. Its product portfolio spans three layers: (1) third-party variable frequency drives from major manufacturers (Mitsubishi, Control Techniques, Schneider Electric, KOSTAL) distributed as an authorized partner; (2) proprietary branded products including PreLEAK®, LEAKCOMP® (1C and 1P variants), LEAKWATCH, DiffDi®, AF-BCR, and PECON+®; and (3) supporting EMC infrastructure such as EMC filters, network filters, line reactors, sine wave filters, motor chokes, harmonic filters, and all-current-sensitive RCCBs (Type B/B+/F). EPA also runs an in-house EMC laboratory and offers on-site EMC testing, fault diagnostics, and engineering consulting compliant with DIN VDE standards.\n\nThe company's revenue model is a hybrid of hardware sales and high-value engineering services. Hardware is sold through quote-based pricing rather than list pricing, with options for direct purchase, custom solutions, and rental. Engineering services — EMC testing, fault analysis, and consulting — are typically delivered through multi-year customer relationships and bundled with proprietary product recommendations. The go-to-market combines direct technical consultation (engineer-led sales), distribution via OEM partnerships, and participation in industrial trade shows. The bundling of proprietary measurement and compensation hardware with standards-compliance expertise creates a defensible specialist position in a niche where generalist drive suppliers lack depth and pure-component suppliers lack system-level support.\n\nOwnership and management are private and not disclosed in the available data. EPA operates with 11–50 employees, consistent with a mid-sized German industrial SMB. The company has won multiple INDUSTRIEPREIS awards (2015 for PreLEAK®, 2018 for LEAKCOMP 1P), signaling third-party validation of its R&D output. Key risks include dependency on a narrow specialty niche, limited geographic disclosure (no explicit international expansion), and absence of visible digital or AI capabilities that could differentiate it from competitors in an increasingly software-enabled industrial market.

Core offering

EPA GmbH develops, manufactures, and distributes industrial components across three domains: drive technology (variable frequency drives, servo systems and system accessories), EMC technology (RFI filters, harmonic filters, line/motor chokes, sine wave filters, absorption filters), and leakage current technology (RCCBs type B/B+/F, compensation, monitoring and diagnosis systems). The company also provides engineering, EMC testing, EMC consulting, leakage current measurement/consulting services, and an equipment rental service to industrial customers.

Product overview

EPA GmbH is a German industrial technology company specializing in three interconnected domains: electrical drive technology, EMC (electromagnetic compatibility) technology, and leakage current technology. Its product portfolio spans from individual components to complete drive systems, complemented by in-house developed EMC filters and leakage current management devices. In drive technology, EPA offers variable frequency drives (VFDs) from major brands (Mitsubishi Electric, Control Techniques, Schneider Electric, KOSTAL) alongside its own Digitax HD servo drives and SH-series servo motors, supplemented by system accessories and comprehensive engineering, commissioning, and on-demand production support services. In EMC technology, the company manufactures a broad range of RFI/EMC network filters across single-phase, three-phase, and three-phase with neutral configurations—including footprint/underdrive filters, PreLEAK® Technology filters, harmonic/overtone filters, line reactors, sine wave output filters, motor chokes, and custom solutions—alongside an in-house EMC testing laboratory and consulting services. In leakage current technology, EPA positions itself as a market leader, offering Type B/B+ and Type F all-current-sensitive RCCBs, PECON+® protective earth monitoring, NF-DAR/KC-DAR leakage reduction filters, LEAKWATCH measurement and analysis systems, DiffDi® differential current diagnostics, and LEAKCOMP® HP/1P/1C compensation devices, plus associated measurement and consulting services. This cross-domain competence enables EPA to address the complex interdependencies between drive systems, EMC phenomena, and leakage currents.
