VST Engineering uses an ANTIDET Dumper personal protective system to safeguard the mechanical separation of an explosion.
The ANTIDET Dumper protective system is a passive valve that provides the unidirectional separation of an explosion (fire and pressure) that spreads from the inlet lines to the upstream facility. It is a passive element that closes the pipeline and isolates the explosion.
The facility itself is often safeguarded by explosion venting or by an explosion suppression system.
The ANTIDET Dumper system comprises its own reflux valve that is situated within a suitable distance upstream on its inlet line. Every valve may be electively equipped with a closing signal.
In an explosion that spreads through pipelines, pressure advances before the flame. In a certain, so-called pre-set distance, their interval is sufficient enough that the pressure wave manages to close the valve before the flame arrives. In doing so, both facilities are separated and the further spread of flame and pressure through the pipeline is prevented.
