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

In 1958 Pfannenberg 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 Pfannenberg’s products are found within the same facility providing critical protection for manufacturing, processes and personnel.

Business philosophy: Protecting Man, Machine and the Environment.

Pfannenberg’s Thermal Management products are used by some of the largest companies worldwide to keep their electronics cool and safe, protecting critical manufacturing processes. Their 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. The visual and acoustic signaling devices Pfannenberg provides 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.

Pfannenberg is global, with its international Headquarters located in Hamburg, Germany and our North-American Headquarters located in Lancaster,  NY.
