Piller

Piller

Piller was acquired by Langley in 2004 and has operated as an independent entity within the Langley Power Solutions division. The firm is headquartered in Osterode, Germany, with subsidiaries across Europe, the Americas, and Australasia. In 2016, Piller acquired Active Power, a Texas-based flywheel UPS specialist, expanding its battery-free power protection capabilities. Piller manufactures UPS systems, power conditioning equipment, and ground power systems for airports, as well as electrical systems for naval vessels. The company's product lines include the SHIELDX™ dynamic power stabilization technology, designed to address disruptive loads from AI-driven data centers. It also produces diesel-based UNIBLOCK™ rotary UPS systems at a facility in Bilshausen, Germany. Piller serves sectors including data centers, banking and finance, healthcare, aviation, and naval defense. The company employs roughly 1,000 people globally, with state-of-the-art manufacturing and R&D facilities spanning 14 hectares in Osterode. Piller's service network supports approximately 10,000 units of high-power UPS equipment in over 50 countries. In 2024, Piller appointed Dean Richards as Co-CEO, and its sibling company Bergen Engines secured over 500MW of orders from Liberty Energy to power AI data centers. Piller is structurally distinct as an operating company owned by Langley Holdings, a diversified industrial conglomerate. Unlike a traditional asset manager, Piller generates revenue through engineering, manufacturing, and service contracts. Its governance sits within Langley's Power Solutions Division, alongside Bergen Engines and Marelli Motori, providing a rare industrial-operating platform with direct access to large-scale power infrastructure markets.
