Who We Are

Pfannenberg, Inc. is a Global Manufacturer of Thermal Management, Liquid Cooling Solutions and Signaling Technologies.

Established in 1954 by Otto Pfannenberg, for over 60 years Pfannenberg has been recognized as a industry leader within the Electrotechnology Industry.

It is our innovation that has driven us to where we are today. In 1958 we invented the Filterfan®, which is recognized worldwide as a leading product to help manage the temperature in electrical enclosures. In 1962 we invented the first industrial flashing light that didn’t require a bulb change once activated.

Many of our products are found within the same facility providing critical protection for manufacturing, processes and personnel.

Our business philosophy: Protecting People, Machines and the Environment.

Our Thermal Management products are used by some of the largest companies worldwide to keep their electronics cool and safe, protecting critical manufacturing processes.

Our Liquid Cooling solutions provide the critical cooling required for manufacturing processes including machine tooling, plastic injection molding equipment, food & beverage extrusion equipment and x-ray/vision systems, to name a few.

Our visual and acoustic signaling devices protect personnel and equipment satisfying numerous alarm, warning, and indication requirements, including: machinery operating status, process monitoring, system startup, and building or area evacuation due to fire, toxic gas leak, chemical spill, or intruder alert.

We are global, with our international Headquarters located in Hamburg, Germany and our North-American Headquarters located in Lancaster, NY. Further locations are in Rotherham (UK), Rueil-Malmaison (FR), Fidenza (IT), Singapore (SG), Suzhou (CN), St. Petersburg (RU) and Indaiatuba (BR).

Together with our sales associates, sales partners and worldwide offices, we have established a far-reaching network covering all international markets. We can be on-site in a short amount of time.

Working Together brings Greater Success – our internal Philosophy of Sharing Competence.

You can trust Pfannenberg to ensure the protection of man, machine and the environment. Our greatest strength comes from reliable industry-leading solutions for technologically demanding applications. Our teams work together cooperatively, in a well-structured and managed manner, continuously developing our work processes to achieve our goals.
