Explosion suppresion Flash

• Flexible and modular
• No pressure vessels, explosives or internal moving parts
• Gas generators with a very long life span (up to 10 years)
• ATEX certified

Explosion suppression system: three components

The FLASH explosion suppression system is a flexible, modular system consisting of:

1. Explosion detectors triggered by static pressure, an increase in pressure, optical monitoring (UV, IR, UV/IR, ...) or a combination of all of these
2. A multifunctional modular control unit
3. Ultra-fast powder extinguishers in different sizes and with various types of connection flanges depending on the application..

This modular design makes it possible to assemble the optimal configuration, both technical and commercial, for each application.

Explosion suppression system: many advantages

The following applies to all configurations:

• No pressure vessels
• Driven by gas generators with a very long life span (up to ten years!!)
• A revolutionary communication protocol between the various components, which makes system faults due to EMC radiation on the wiring nearly impossible!
• High quality electrical connections due to the use of cables with moulded connectors (worldwide standard available)
• Reduced installation, operating and maintenance costs.

The control unit works with all equipment supplied by Stuvex, including fast closing valves, which is very beneficial.

For more details on the detection and the control unit, we refer to their respective datasheets.

Extremely fast explosion suppression

The detector continuously monitors the volume to be protected. In the case of a pressure increase or optical detection (depending on the system configuration and settings), the detector will send a signal to the control unit, which in turn will trigger the gas generators of the extinguishing agent bottles.

Then, within a few milliseconds, the huge amount of gas necessary to inject the extinguishing powder into the installation is produced. The powder kit, the extinguishing agent bottle and the gas generator itself are completely pressure free under normal working conditions. The injection of the extinguishing powder extinguishes the flame front. In addition, there is always enough extinguishing powder provided to make the entire volume inert so that no secondary explosion can occur.

For this reason, the process (and certainly the blowers) must be stopped immediately after Flash explosion suppression system is triggered, in order not to exhaust the extinguishing powder. If this cannot be guaranteed, cut off valves must be installed or supporting measures (such as steam injection) must be taken.

Explosion suppression for specific industries

The Flash explosion suppression system is available in various configurations, adapted to your needs. Thus, in addition to the standard solution with the necessary flanges (in normal or stainless steel) simply welded to the equipment, specific solutions also exist for the following:

• Hygienic applications (pharmacy, (baby) food production...), where special attention is given to those materials that come into contact with the product: the surfaces are smooth, without gaps,...
• Processes with CIP cleaning, both automatic and manual, up to 300 bar
• Fast installation methods making use of the HPL system, which allow normal installation times to be cut in half
• Weld-free installation methods that make use of the HPL system, which makes prior cleaning of the installation unnecessary
• Vibrating process parts (e.g. fluid bed)
• A combination of the above possibilities.

Many of these solutions are custom-made, developed in consultation with the customer.

ATEX certified explosion suppression

This product is a certified ATEX safety system. Consequently, any application must be based on the instructions contained in the ATEX certificate, the product specifications and the user manual. Depending on model, the system is suitable for installation in Ex zones 1, 2, 21, 22.
