Today, type D big bags have
become more familiar to the groundable bag
users, as a challenging alternative for Type
C bags.
The usage of Type D big bags
are much more practical than the groundable
bags and they avoid operator errors. The
special construction of the Type D fabric
eliminates the need of an earth connection
during the filling and discharging of
materials.
Crohmiq® is the first
true Type D fabric to appear in the market
place since the early 1990’s. The fabric was
developed to cover a growing need for an
ungrounded static protective solution for
bulk packaging.
Due to its reputable
safety record, as of today, over 500 leading
companies worldwide prefer FIBCs
manufactured from Crohmiq® fabric for their
static bulk bag packaging requirements.
Today Crohmiq® is the
only Type D fabric in the market which
complies with the IEC standards.
Cesur Packaging is proud
to become the first manufacturer awarded a
licence to produce the patented Crohmiq®
fabric from Texente LLC.
why type D ?
- Unlike Type C FIBC's, Type D FIBC's
do not require grounding.
- Can be used for the transportation
of flammable powders, or when flammable
solvents or gases are present around the
FIBC..
- It provides safety equal to a
grounded Type C FIBC without the human
error risk factor.
- Type D fabric permits the
dissipation of the charges in to the
atmosphere by corona discharge.
- A corona discharge is one form of an
electrostatic discharge with a low
energy, unlike sparks or brush
discharges, it does not give way to
ignition of flammable or explosive
atmospheres.
why crohmiq ?
- Only CROHMIQ® 's patented technology
provides a level of safety equal to a
properly grounded Type C FIBC, but
without the risks of human error. For
these reasons, leading global companies
continue to switch from Type C FIBC to
the optimum safety of CROHMIQ® FIBC.
- CROHMIQ® 's properties are permanent,
therefore, its static dissipative
performance does not decay with time nor
wash off during wet reconditioning
processes as many pseudo Type D FIBC's
do.
- CROHMIQ® fabric is FDA compliant.
- Internationally recognised as the
leading Type D static protective FIBC
fabric.
- It is the only Type D fabric that
will comply to the IEC61340 - 4 - 4 :
2005 standards.
warnings:
If
the surface of the Type D FIBC is
contaminated or coated by any conductive
material (such as water, oil etc) then spark
discharges may occur.
therefore
-
Precautions should be taken in order to
prevent the surface contamination.
- No conductive object (such as metal
items and tools) should be placed on the
FIBC.
- All conductors in the presence of
flammable or explosive atmospheres
should be grounded.
