Suppression

Hot WaterSuppression System

ATEX Hot Water Suppressors were specifically designed for the Dairy Drying Industry. With water stored in a temperature and pressure controlled unit, it provides a unique advantage in larger vessels. Before the advent of HWS DCS were used on these vessels.

But the DCS had two major drawbacks discharge distance as they were practically limited to 10 feet of throw as the discharge velocity was constantly decreasing after release from the suppressor. It also required a large amount of cleanup. The HWS do not have a cleanup problem. On release, the Water flashes to a vapor accelerating and providing an unobstructed discharge pattern in the vessel making it ideal for the large vessel volume.



The ATEX Hot Water Suppression system is an innovative solution to the complex problem of non-contaminating explosion suppression in large volumes. Superheated water is released under pressure to quickly disperse microscopic droplets over a large area creating an inert atmosphere which immediately extinguishes the flame. The big advantage is the use of water that is kept hot in the suppression bottles. If triggered, your products only come into contact with water. This technology is, therefore, most suitable for use in the foodstuffs industry, particularly for drying milk in spray towers. The fast activation - or opening - of the suppression bottle is achieved through gas generators and a special, reusable leaf valve. This can easily be exchanged after triggering. The entire system is therefore fully ready for operation again in a very short time and your plant can soon start operating again.
The gas generators activate the suppression bottles in the event of an explosion. A specially developed, reusable leaf valve ensures that the bottles are opened quickly. The extinguishing powder is suddenly introduced into the developing explosion cloud, acting specifically on the explosion flame. The flames are prevented from spreading. Once having been triggered, the valve can easily be replaced, allowing the entire system to be activated again within a very short time. This avoids long shutdown time for your plant.


FEATURES
Safe to use thanks to encapsulation of the trigger mechanism
Total control through electronic addressability
No expensive blasting agents requiring extensive maintenance
Fast restoration through a reusable valve
User-friendly replacement system
Push-in connection of the cabling (Plug and Play connection)
More safety when mounting or modifying the bottles through manual locking mechanisms
Fast, economical refilling.

The ATEX System is the only System to be independently certified to meet the ANSI SIS SIL Level 2 requirements. In short, if a device cannot be supervised for functionality it must be of redundant supply. For instance, Gas Generators cannot be definition be fully supervised so SIS requires redundancy and ATEX has complied with redundant Gas Generator on all suppressors.
The ATEX Detection and Control System provide the most user-friendly and powerful diagnostic tool in the industry. The ATEX Decentralized Modular System allows for ultimate flexibility. Expansion does not require the redesign of the system.


ATEX PXD Sensors continually monitor the process for overpressure developments on dynamic and static bases. In addition, a heartbeat signal is continually monitored to ensure the reliability of the device. Through sophisticated exclusive algorithms, ATEX sensors can filter out most electrical spikes and variances that would normally cause false activations with analog sensors.
The last four real-time alarm curves for each PXD Sensor are stored for review and analysis. Only with the curves from both sensors on an independent basis can detection signals be evaluated and compared for a proper response. Besides Control Unit Diagnostic LED’s for each sensor, they can be individually interrogated on command for settings, real-time pressure, and sensor history.
