Explosion Venting
with and without
TARGO-VENT
I
n contrast to their
consequences,
explosions are
only discernible
to a limited extent by sight
alone. They happen within a
few milliseconds, yet leave
behind considerable damage.
Different approaches of
explosion protection are
implemented to limit this
damage.
Bursting discs are often used
in facilities where relief of the
explosion in the surrounding
area is possible. Bursting discs
are relief fittings, which are
extremely economical and
relatively easy to manage.
However, this type of
traditional explosion pressure
relief presents a big problem
for many facility operators –
extensive safety areas have
to be set up around the relief
area to protect people and
machines. These areas cannot
be used.

New methods of
free explosion
pressure relief
Intelligent explosion protection does
not necessarily have to be expensive or
complicated. An innovative technology makes
it possible to divert the shock wave and flames
of an explosion in a controlled manner. The
result being that the required safety area is
reduced, and spaces that are freely available are
increased. People and machines are protected
in the best possible way.
especially for bursting discs,
which guides the pressure
relief specifically into areas, in
which there is no danger for
the adjoining infrastructure.

beneath it, and can therefore
also assimilate large kinetic
forces resiliently. The damper
absorbs the enormous
repulsive forces of the
explosion energy and guides
the flames and shock wave in
the desired direction.
Depending on what’s required
the flames and shock wave
are diverted at a defined
angle of approx. 30° to
approx. 45° upwards or to
the side. Facility operators
can therefore minimise the
safety areas around the vent
opening. The utilisable area is
increased.
A further advantage of
TARGO-VENT: the top module
is made in all the usual
bursting disc sizes, so that
retrofitting in existing units
can be undertaken without
a problem. Conversions or
new buildings are protected
by TARGO-VENT without the
explosion protection concept
of the existing facility having
to be significantly altered.
TARGO-VENT is assembled on
the bursting disc in a spacesaving manner. There is no
need for expensive baseplates
or reinforcements. The system
is made from maintenancefree stainless steel materials
and, in combination with
REMBE® bursting discs and
pressure relief panels, is typetested in accordance with
the ATEX Directive 94/9/EC
(ATEX 114) and authorised in
accordance with (FSA 13 ATEX
1637).
