Founded in 1954 and headquartered in Hamburg, Germany, Pfannenberg specializes in thermal management, liquid cooling solutions, and signaling technologies designed to protect people, machines, and the environment. Pfannenberg has a global presence in North America, Europe, Asia, and South America.
Its thermal management solutions, like the original Filterfan, cooling units, and heat exchangers, protect machines, preventing overheating and ensuring optimal performance of electrical equipment. Its Liquid cooling systems, including packaged chillers, offer precise temperature control essential in industries such as machine tooling, plastics, and food processing. Additionally, its signaling products—visual and audible alarms—enhance workplace safety by providing critical alerts protecting people in industrial settings.
Committed to innovation, Pfannenberg created groundbreaking products like the Filterfan (1958), the maintenance-free flashing light (1962), and, most recently in 2025, its energy-efficient Hybrid Series Cooling Unit. Pfannenberg is certified to ISO 9001 and ISO 14001.
