In-Line Detonation Flame Arrester for stable detonations and deflagrations in a straight through design with shock tube, bi-directional Design with two temperature sensors Design with one temperature sensor c dismantling dimension for servicing (temperature sensor) PROTEGO® DA-SB Special Features and Advantages • optimized performance due to the patented Shock Wave Guide Tube Effect (SWGTE) • low number of FLAMEFILTER® discs due to the patented Shock Wave Guide Tube Effect (SWGTE) • modular design enables replacement of the individual FLAMEFILTER® discs • different designs allow scalable pressure loss over the area of the FLAMEFILTER® • maintenance-friendly design • advanced design for higher operating temperatures and pressures • bi-directional operation, as well as any flow direction and installation position • installation of temperature sensors possible • minimal pressure loss resulting in low operating and lifecycle costs  Connection to the protected side (only for type DA-SB-T-...) • Cost-effective spare parts • installation of stabilized FLAMEFILTER® possible Function and Description 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. The devices are symmetrical and offer bi-directional flame arresting for deflagrations and stable detonations. The arrester essentially consists of two housing parts with an integrated shock tube (1) and the PROTEGO® flame arrester unit (2) in the center. The PROTEGO® flame arrester unit is modular and consists of several FLAMEFILTER® discs (3) and spacers firmly held in a FLAMEFILTER® casing. The number of FLAMEFILTER® discs and their gap size depends on the arrester‘s intended use. By specifying the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid, the optimum detonation arrester can be selected from a series of approved devices. The PROTEGO® DA-SB flame arresters are available for all explosion groups. The standard design can be used with an operating temperature of up to +60°C / 140°F and an absolute operating pressure up to bar / 15.9 psi. Numerous devices with special approval for higher pressures (see table 3) and higher temperatures are available upon request. Type-approved in accordance with the current ATEX Directive and EN ISO 16852, as well as other international standards. ® • use of maintenance-friendly PROTEGO® flame arrester unit possible Design Types and Specifications There are four different designs available: Basic in-line detonation flame arrester In-line detonation flame arrester with integrated temperature sensor* as additional protection against short-time burning from one side In-line detonation flame arrester with two integrated temperature sensors* for additional protection against short-time burning from both sides In-line detonation flame arrester with heating DA-SB - H jacket Additional special flame arresters upon request. *Resistance thermometer for device group II, category (1) 2 (GII cat.
