CHARLOTTE, NORTH CAROLINA, US — REMBE has introduced a new and improved EXKOP isolation system that is available for more applications.
The system may be used for ST 2 dusts, reduced explosion pressures (Pred) of up to 2 bar and larger diameters. The upgraded controllers allow for flexibility as process requirements change.
Isolation is required per NFPA and essential to protecting adjoining system components against the spread of combustible dust explosions. Process equipment usually is connected by pipelines through which, if an explosion occurs, fire and pressure spread very rapidly. The intensity of the explosion in connected containers is increased by pressure piling and flame jet ignition.
This sequence of events can be prevented by the EXKOP isolation system, consisting of a control panel, triggering devices, and one or more quench valves. The integrated elastomer seal within the quench valve closes within milliseconds, triggered by a signal from a burst indicator on a REMBE explosion panel, an infra-red signal, or a pressure sensor. The REMBE EXKOP system is fail-safe and easy to test/reset at the press of a button.
