INDIVIDUALIZING IS ONE OF OUR GREAT STRENGTHS JDli>ersi£i Some 60 years ago, PROTEGO® began to develop customized valves and vessels 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 FLAME FILTER® 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...

Patented Technology is our Safety Principle PROTEGO® flame arresters whose basic concept was devised in the late 1920ies by Robert Leinemann, the founder of our company, is a special design of flame arresters which, in simplified terms, adopt the physical principle of flame-quenching gaps. Selecting the proper gap length and gap width as a function of the flashback velocity of explosive mixtures while keeping the flow resistance at a minimum (pressure drop) represents the secret of best-possible operation. In the past sixty years, PROTEGO® flame arresters have been continuously improved, with patents...
