Function and Description

Prevention of Flame Spread in Tank During Ignition

Reduction of Flame Propagation Speed

When a highly accelerated pipe deflagration Deflagração Explosion propagating at subsonic velocity (EN 1127-1:1997). or detonation Detonação Explosion propagating at supersonic velocity and characterized by a shock wave (EN 1127-1: 1997). occurs, the combustion pressure and flame propagation speed are substantially reduced by the design and converted into a low-energy deflagration that is then stopped by the remaining immersion liquid.

For Explosion Groups IIA to IIB3

The application range for the device is a product vapor / air mixture temperature of up to +60°C / 140°F and an absolute pressure of up to 1.1 bar / 15.9 psi. This covers all possible operating conditions of empty lines for flammable liquids. The liquid detonation arrester Corta-chamas à prova de detonação Flame arrester designed to prevent the transmission of a detonation. is designed for pressures of up to 10 bar / 145 psi, resists explosion Explosão Abrupt oxidation or decomposition reaction producing an increase in temperature, pressure, or in both simultaneously. pressure, and provides protection for almost all flammable liquids. The device is approved for explosion groups IIA to IIB3 (NEC group D to C MESG ≥ 0.65 mm).

Many Individual Certifications

Special designs with a cleaning cover for highly viscous and contaminated liquids are available. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
