Explosion isolation protects adjoining areas and system components against propagating combustible dust explosions. Process equipment is usually connected by pipelines through which, if an explosion occurs, fire and pressure can spread very rapidly. Propagating explosions pose increased risks of injury, equipment damage and secondary explosions. The intensity of the explosion in connected vessels is increased by pressure piling and flame jet ignition.
The REMBE EXKOP isolation system can prevent this sequence of events. It consists of a control panel such as the new EXKOP Express, triggering devices, and one or more fast-acting isolation devices.
In the event an explosion is detected by either infrared optical sensors or pressure switch signals, the EXKOP Express controller will activate the connected explosion isolation systems, such as the REMBE QV II or QV III quench valve.
The integrated elastomer seal within the quench valve closes within milliseconds and is easily reset at the press of a button.
For abrasive materials, the REDEX slide and RSV fast-acting knife gate valves provide reliable bi-directional protection.
The REMBE EXKOP Express can also be used to activate the Q-Bic chemical extinguishing barrier in one or multiple pipes. The Q-Bic system can protect large-diameter pipes, and the hygienic interface is compatible with sanitary food applications such as spray dryers and pneumatic conveying.
The REMBE EXKOP System protects people, property, and processes from the effects of a propagating dust explosion.
