What PROTEGO does
PROTEGO (legal entity: Braunschweiger Flammenfilter GmbH) is a German industrial safety equipment manufacturer founded in 1954 and headquartered in Braunschweig. The company designs and produces flame arresters, breather valves (pressure and vacuum relief valves), and tank equipment for explosion protection, pressure management, and emissions control at industrial storage and processing facilities. Its core technology platforms include proprietary 10% full-lift valve technology (enabling valves to reach full lift with only 10% overpressure versus conventional 40-100%), the FLAMEFILTER modular flame arrester element design, and the UB/SF diaphragm valve that uniquely combines dynamic and static flame arrester functions in a single device.
The company serves four primary industrial verticals: oil and gas (upstream and downstream), chemical processing, pharmaceutical manufacturing, and bio-energy, with additional specialty offerings for cryogenic storage (LNG, liquid oxygen, liquid nitrogen) and hydrogen economy applications. PROTEGO operates a global direct field sales model through 10 wholly-owned subsidiaries covering Germany, Brazil, China, France, India, the UAE, Austria, Spain, Switzerland, the UK, and the USA, supported by a 750+ person workforce that includes a dedicated R&D technology center with explosion testing and flow measurement capabilities (DN 25 to DN 1000). The business model is B2B industrial equipment sales with quote-based custom configurations, multi-year contracts, and bundled engineering services. No revenue figures are publicly disclosed; the company is privately held under Managing Directors Dr.-Ing. Michael Davies and Dr.-Ing. Philip Bosse with no identified external parent, private equity, or venture capital ownership.
