Explosion Suppression

Explosion suppression is a reliable way of mitigating the effects of an explosion in process vessels, pipes and ducts.  By early detection of the incipient explosion and rapid discharge of dry chemical extinguishing powders, the explosion pressure within the vessel can be greatly reduced.

The Explosion Suppression System comprises the following items:-

  • Control Unit (single or multiple zones)
  • Explosion pressure detector (static over pressure or rate of pressure rise)
  • Suppressors

 The Control Unit provides the interface between the suppression system and the process controls.  It has an automatic battery backed power supply and also monitors the state of each individual component.  The system is fully addressable, meaning that the status of every part of the system is fed back to the Control Unit and can be displayed in real time.  The Control Unit also has the option for remote access control and setting.  A built in modem allows engineers at the factory to “call in” and monitor the system from remote locations.  This dramatically reduces the costs of call-outs and service visits.

 If exposed to flame the valve can be re-used but the seals and valve plate must be checked before re-entering service. The unit does not necessarily need to be returned to the manufacturer.  Savings are made in spares holding and down-time as a result.  The result is a cost effective solution for plant designers and end users for all industries.
