The Atex Dry Chemical-based Advanced Inerting System is a multi-purpose, high efficiency suppressor discharging non-toxic flame-extinguishing powder.

Features

High efficiency explosion suppression system.
New high-speed gas generator actuated release valve removes the need for explosively initiated rupture discs.
Full actuator redundancy doubles your integrity level.
Lockable valve acts as simple arm/disarm mechanism.
Discharged systems can be refilled on-site.
Safe and non-toxic, compatible with a wide range of processes.
Can be used inside all plant areas regardless of ventilation.
Full system monitoring.

Concept and Operation

When the suppressor receives a 'fired' signal from a control system and/or sensor it fires the gas generators, releasing the valve. Extinguishing suppressant is then discharged under 60bar pressure into the protected plant.

This is the first system to address the high cost and supervision requirements of traditional suppressors. Compared to previous systems which employ complex monitoring and actuation devices, the ATEX Powder Suppressor comprises simply a valve and two gas generators. This makes for high reliability and low maintenance. The dual gas generator valve actuator provides redundancy for added safety. Another major benefit, on-site refurbishment dramatically reduces downtime after a suppressor(s) discharge.
