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 Man, Machine 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.
