What Pq Engineering Nosswitz Gmbh does

PQ Engineering Nosswitz GmbH is a privately held, family-owned German engineering firm founded in 1973 and headquartered in Otterfing. The company designs, sources, and supports power quality solutions—active filters, passive filters, hybrid filters, voltage stabilizers, static var generators, transient filters, power factor correction, and measurement equipment—for industrial manufacturers, healthcare facilities, critical infrastructure operators, and energy producers facing harmonic distortion, reactive power imbalance, voltage sags, and transients that would otherwise cause production downtime and equipment damage.

The product portfolio is anchored by the proprietary PQE hMF hybrid modular filter (auto-tuning, Comsys PPMv4 modules inside), the PQE aHF active filter built on silicon carbide technology with greater than 98.5% efficiency and UL certification, the OSKAR DVR AVC dynamic voltage restorer, the SVG static var generator cabinet rated at 400 kVar with sub-20-millisecond response, and the SineTamer transient filter. Complementary in-house technologies include the PQE UBM/uBF broadband modules for supraharmonics, the LBANK outdoor medium-voltage compensation system, and the FKA-APP control software integrated on Janitza UMG hardware. Grid simulation is performed with DIgSILENT PowerFactory for classification compliance and network planning. The company provides bundled services under its 4A concept covering analysis, design, implementation, and after-sales support, and is certified to DIN ISO 9001:2015 and DIN ISO 45001:2018.

Commercially, PQ Engineering runs a sales-led, project-based enterprise go-to-market delivered through direct field sales and inside-sales phone consultation, with named contacts (e.g., Ulrike Nosswitz). Revenue is generated from proprietary and third-party hardware sales plus professional services for measurement, design, installation, and after-sales; pricing is quote-based with a fixed-price (Festpreis) value proposition and multi-year service arrangements. Customers span automotive plants, hospitals, chemical facilities, beverage producers, geothermal and maritime operators, data centers, and entertainment/events, with project references in over 100 cities across Europe, the Americas, Asia, the Middle East, Africa, and Oceania, executed by a team of 1–10 employees.
