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.
Three highly sensitive pressure sensors
are arranged in a way that maximizes
sensitivity while avoiding activation from
vibrations. In the event of a power cut, the
internal battery continues operation for
at least eight hours. This provides enough
reaction time to establish a secure energy
supply.
PROTECTION FOR DUSTY PRODUCTION
ENVIRONMENTS
The IPD explosion suppression and
isolation systems are used in all production
environments where flammable dust is
created or powdered substances are stored,
handled and processed. Examples include
the chemical or pharmaceutical industries,
as well as the production of foods, feed and
engineered woods. By responding to the
incipient stage of a dust explosion, the IPD
System reduces the pressure developed by
the combustion event to a safe low level, as
low as 0.2 bar. This is the combined result
of having a low nitrogen gas pressure to
disperse the extinguishing agent and the
use of sodium bicarbonate as a fast heat
absorbing agent.
