PROTEGO® - Braunschweiger Flammenfilter GmbH

Since 1954 PROTEGO® has built and provided safety devices and tank equipment, now with the help of more than 450 employees worldwide. Within our area of expertise, we are the technology leader. We provide global services for our customers, which include research and development, application-specific engineering, and overall protection system design. Our customers know they can trust in our products and high quality and development standards for process engineering, the petroleum, chemical, and pharmaceutical industries and the bio-energy sector.
Some 60 years ago, PROTEGO® began to develop customized valves designed to protect plants and equipment against explosions, as well as breather valves that meet most stringent requirements regarding performance, keeping pressure constant, and seal-tight functions.
That process entailed not only the original Braunschweiger FLAMEFILTER® flame arresters, but also numerous other innovations which resulted in many patents. It is through close cooperation with scientific institutes and authorities that new technical challenges have been met again and again to satisfy and environmental protection needs.
PROTEGO® offers a vast range of flame arresters, valves and tank accessories that have been tailored to what the market requires. The products have been brought into play by industrial users in varied applications.
FLAME ARRESTERS
PROTEGO® flame arresters reliably protect plants and equipment designed to produce, store, transport and handle combustible gases and flammable liquids of all hazard classes, against endurance burning, deflagration and detonation.
VALVES
The unique PROTEGO® valve technology minimizes product losses and reduces emissions. For isolated cases and dedicated applications, PROTEGO® offers a range of pressure and vacuum relief valves with and without incorporated PROTEGO® flame arrester unit.

PROTEGO® is a profitable, independent, international family business that, while developing and manufacturing safety valves and equipment, is the top-notch competence source for technology, quality, availability, services, engineering, and
consultancy. Our fields of activities are explosion protection as well as environmental conservation through retaining and relieving pressure in the exploration, processing and storage of flammable liquids and gases.
