BR/TS
The PROTEGO® BR/TS-80-IIB-P1.6 detonation flame arrester was developed for protecting tankships but can also be used for containers. These devices are especially used on tank ships operating on inland waterways or coastal shipping. The device is installed on the tank or a pipe section connected to the tank with a nominal size of 250 mm / 10" and connected to the vapour balancing line (DN 80 / 3"). The individual tanks connected via the vapour balancing line are technically decoupled by the detonation arresters and protected.

D/PA(L)
D/PA(L)
The D/PA(L) type PROTEGO® valve is a highly developed pressure and vacuum relief valve with excellent flow performance. Typically, the valve is installed in the in-breathing and out-breathing lines of tanks, vessels, and process equipment to protect against unallowable overpressure and underpressure. The valve prevents emission losses almost up to the set pressure and prevents air intake almost up to the set vacuum. The product vapors can be released through a collective line connected to the line flange on the pressure side. Backflow is not possible, i.e. the valve can be used as an overflow valve or backflow protection.

DA-E
DA-E
The PROTEGO® DA-E series of detonation arresters are distinguished by its eccentric housing shape. When condensate accumulates within the PROTEGO® flame arrester unit, the design allows the liquid to drain without collecting large amounts in the housing. The eccentric design of the device has distinctive advantages over the classic flame arresters when installed at lower depths.

DA-G
DA-G
The PROTEGO® DA-G series is a compact in-line detonation flame arrester for installation in pipes with diameters up to 3“ and is used, for example, in industrial applications such as gas analysis lines.

DA-SB
DA-SB
The in-line detonation flame arresters type PROTEGO® DA-SB are the newest generation of flame arresters. Based on flow and explosion dynamic calculations as well as decades of field tests, a product line was developed that offers minimum pressure losses with maximum safety. The flame arrester uses the Shock Wave Guide Tube Effect (SWGTE) to separate the flame front and shock wave. The result is an in-line detonation arrester without a classic shock absorber, which minimizes the use of FLAMEFILTER® discs.

DA-SB-PTFE
DA-SB-PTFE
The in-line detonation flame arresters type PROTEGO® DA-SB-PTFE are the latest generation of flame arresters and are distinguished by its unique resistance to adhesive and corrosive media. The use of fluoroplastics as a high-tech housing coating and as solid material for the flame arrester element is unique throughout the world.

DR/ES-V
DR/ES-V
PROTEGO® DR/ES-V series uniquely combines the function of an in-line detonation flame arrester with the function of a pressure relief valve in one device. The device protects against deflagration and stable detonation. The weight-loaded pallet type valve (5) integrated in the shock absorber (1) of the in-line detonation flame arrester is designed as a pressure relief valve. The set pressure of the valve is adjusted in the factory and can range from 2 to 35 mbar (0.8 to 14 inch W.C.). After the pressure increases 40% from its set pressure, the valve completely opens to yield the maximum volumetric flow. If installed in vent headers connected to storage tanks, the valve pallet works as a check valve. This means that the product cannot flow back from the suction line into the tank. Although several functions are integrated in a single housing, the device is extremely easy to service, which is primarily due to the right-angle design.

DR/SV
DR/SV
The PROTEGO® DR/SV flame arrester series ideally combines the function of a detonation arrester with the advantages of a shut-off valve. In case of ignition, the fire can be stabilized within the flame arrester when the flammable gas continues to flow. Inside the detonation arrester, is a valve (1) that closes in case of fire, stops the additional supply of fuel and extinguishes the flames. Temperature sensors in combination with an emergency switch off do not have to be installed if the type PROTEGO® DR/SV device is used. This device is particularly useful for the sucction-side protection of compressors and pumps.
