THE EFFECTIVE WAY TO SUPPRESS
AND STOP EXPLOSIONS

Solutions for chemically suppressing and
isolating explosions by BS&B Safety Systems
feature a modular design and do away with
pyrotechnic triggers. This makes installation,
repair and transport easier.
Dust explosions in industrial facilities can
be devastating due to the extreme rise in
pressure. IPD, the system for suppressing and
isolating dust explosions from BS&B Safety
Systems, detects critical rises in pressure to
the millibar and reacts at lightning speed. The
highly effective extinguishing agent smothers
any flame in an accumulating explosion in a
fraction of a second, long before the explosive
pressure is unleashed. When used for
isolation, the IPD system stops the explosion
spreading to connected parts of the facility.
This provides effective protection to people,
machinery and the environment.

Modular design means easy on-site resetting
To make sure the IPD system is ready for
use again quickly after being triggered, the
designers at BS&B developed a new, modular
design. This allows for immediate resetting
on site, reducing production downtime to
a minimum. Unlike other solutions on the
market, the owner or operator can reset the
system independently after triggering.
The extinguishing unit consists of
an unpressurized, easily replaceable
extinguishing agent cartridge and a
pressurised container that is filled with
nitrogen during installation or reset. The lack
of a pyrotechnic trigger means that none of
the individual components or the completed
system are classified as hazardous goods.
This makes both handling and spare parts
logistics and management much easier. It
also shortens delivery times and reduces cost
of ownership, as there is no need to comply
with the obligatory safety regulations for
transport that apply to conventional systems.
Furthermore, the extinguishing unit requires
no extra discharge nozzle for the agent.
Instead, the integrated rupture disc becomes
an aerodynamic outlet when activated. The
design avoids the use of plumbing that can
become blocked.
Alongside the extinguishing unit, the
explosion suppression and isolation system
features a control unit with touchpad and
the patented Triplex sensor. This ensures
constant, real-time monitoring of the process
pressure, allowing for fast and reliable
activation.
