Introducon
The 924 is now available for use in Ex applicaons. The 924EX oers the same
outstanding levels of performance, reliability, easy maintenance and features
associated with Meech Pulsed DC technology. It is ATEX approved and can be
used in zone 1 applicaons. It is designed to control stac charges in short
range applicaons and is parcularly suited for use in hazardous areas and
applicaons such as gravure prinng, lm extrusion and coang.
The 924EX is a compact pulsed DC ionising bar designed to be used on the
most arduous stac eliminaon problems. The special resisve coupling
of its emier pins renders them shockless, whilst giving powerful stac
neutralisaon performance.
The 924EX is powered by the Hyperion 233v4 HL Pulsed DC Controller. They
are designed to work together as a system meaning that customer’s can now
benet from the features associated with the Hyperion range in hazardous
environments. The output voltage, frequency and balance can all be adjusted
to suit parcularly dicult applicaons and very sensive materials found in
EX zones.

Features and Benets of 924EX
Overall look
The prole of the 924 EX Bar provides ionisaon through alternang posive
and negave emier pins mounted in a PC ABS extrusion. The emier pins
are resisvely coupled to the high voltage pulsed DC source, rendering the
emiers shockless to touch and will give many years of service.
Compact Size and Full Length Ionisaon
The small cross-seconal size of the 924EX means that it will t into ght
installaon posions. The bar has been designed to give full performance
over its enre length, ensuring full coverage of webs that run close to
machine frames.
Sealed Contrucon
Sealed IP67 construcon allows the bar to be used in harsh environments,
subject to wash-down or where there is the likelihood of spillages. Please
note. should the bar become wet, it must be thoroughly dried before being
powered-up.
7
Shockless Titanium Emiers
As with our Hyperion range bars, the 924EX uses Titanium emier pins.
Almost indestrucble, these pins will give many years service. For the comfort
and safety of the operator, the pins are resisvely coupled and shockless to
touch.
Divider
The 924EX is designed to operate in dirty, factory environments. To minimise
the impact of contaminaon and maximise the interval between cleaning, the
bar features a divider between the posive and negave emiers. This divider
is an essenal feature of the bar.
8
T-Slot
Mounng of the bar is made easy using the T-Slot at the rear of the bar. The
M4 T-Bolts used are the same as used on other Meech Pulsed DC bars.
