DAZ-S

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 Arrête-flammes antidétonation Flame arrester designed to prevent the transmission of a detonation. without a classic shock absorber Amortisseur de choc A shock absorber is a device that reduces the kinetic energy of a detonation. , which minimizes the use of FLAMEFILTER® discs.

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 Operating temperature Temperature reached when the equipment is operating under design conditions. of up to +60°C / 140°F and an absolute operating pressure Pression de service Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to bar / 15.9 psi. Numerous devices with special approval for higher pressures (see table 3) and higher temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
