1 for stable detonations and deflagrations in a straight through design with shock tube, bidirectional Ø a Design with one or two temperature sensors NG c dismantling dimension for servicing (temperature sensor) Type-approved according to ATEX Directive 94/9/EC and EN ISO as well as other international standards. Special Features and Advantages optimized performance from the patented Shock Wave Guide Tube Effect (SWGTE) less number of FLAMEFILTER discs from the use of the patented shock tube (SWGTE) modular fl ame arrester unit enables each individual FLAMEFILTER discs to be replaced and cleaned different series allow increase of FLAMEFILTER b size for given flange connection resulting in lower pressure drop across the device 1 Function and Description 2 3 Connection to the protected side (only for type DA-SB-T-...) The in-line detonation fl ame arresters type are the newest generation of fl ame arresters. On the basis of fl uid dynamic, explosion dynamics calculation and decades of experience from fi eld tests, a product line was developed that offers minimum pressure loss and maximum safety. The fl ame arrester uses the Shock Wave Guide Tube Effect (SWGTE) to separate the fl ame front and shock wave. The result is an in-line detonation arrester without a classic shock absorber; in addition the use of FLAMEFILTER discs is minimized. The devices are symmetrical and offer bidirectional fl ame arresting for defl agrations and stable detonations. The arrester essentially consists of two housing parts with an integrated shock tube (1) and the PROTEGO fl ame arrester unit (2) in the center. The PROTEGO fl ame arrester unit is modular and consists of several FLAMEFILTER discs (3) and spacers fi rmly held in a FLAMEFILTER cage. The number of FLAME- FILTER discs and their gap size depends on the arrester s conditions of use. By indicating the operating parameters such as temperature, pressure and explosion group, and the composition of the fl uid, the optimum detonation arrester can be selected from a series of approved devices. The fl ame arresters are available for all explosion groups. The standard design can be used up to an operating temperature of +60 C / 140 F and an absolute operating pressure up to 1.1 bar / psi. Numerous devices with special approval can be obtained for higher presssures (see table 3) and higher temperatures. service-friendly design expanded application range for higher operating temperatures and pressures bidirectional operation as well as any direction of flow and installation position installation of temperature sensors are possible minimum pressure loss and associated low operating and life-cycle cost cost efficient spare parts Design Types and Specifications There are four different designs available: Basic in-line detonation fl ame 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 jacket Additional special fl ame arresters upon request Resistance thermometer for device group II, category (1) 2 (GII cat.
