We are engaged in many sustainable projects. We are Alliance Member of the Sustainability Initiative Blue Competence and commit ourselves to these twelve Sustainability Guidelines of the Mechanical Engineering Industry.
Safe systems in practice
PROTEGO® devices are used in a wide range of industrial applications. A safe process requires reliable protection for every conceivable operating parameter. Practical examples show how systmes can be made safe and how PROTEGO®
Protection of flares
Equipping elevated flares or ground flares with DA-SB detonation flame arresters. Equipping the emergency vent stack with VD/SV-HRL deflagration-proof endurance burning-proof pressure and vacuum relief valve. Gasholders with DR/SBW
Protection of Processing Facilities
Tank farms for flammable liquids with pressure and vacuum relief diaphragm valve UB/SF, connection to gas vent header system with detonation flame arrester DR/ES-V or DR/ES and pressure or vacuum relief valve DZ/T.
Pressure and Vacuum Relief Valves for Cryogenic Storage Tanks
Decades of experience in manufacturing pilot-operated pressure/vacuum relief valves, our expertise in computer-optimized design, and our extensive test facilities form the basis for the development of
Working principle of Flame Arresters
Flame Arresters (or ‘flame arrestors’) are designed to allow the flow of gases, liquids, etc. and to prevent flame transmission. PROTEGO® Flame Arresters are composed of individual FLAMEFILTER® (flame arrester discs),
PROTEGO® Breather Valves
In closed containers or tanks containing liquids, effectively managing pressure is crucial. To ensure secure operations, it is vital to have a dependable mechanism for releasing accumulated pressure and compensating for vacuum conditions.
The deflagration proof gauging pipes with integrated flame arresters type PROTEGO® PU are used for explosion-proof gauging of tank contents. The gauging pipes of type PROTEGO® PU consist...
