Application of European Directives
Pressure Equipment Directive
The equipment conforms to this directive (see
"Manufacturer's Declaration" section) and can be
used for the following media:
CW 41
Fluids of group 2
(for fluid media only)
CW 41/4
Fluids of group 1
Fluids of group 2
(for fluid media only)
ATEX Directive
CW 41 and CW 41/4
The equipment does not have its own potential
ignition source and is not subject to this directive
(see "Manufacturer's Declaration" section).
When installed, static electricity may arise between
the equipment and the connected system.
When used in potentially explosive atmospheres,
the plant manufacturer or plant operator is
responsible for discharging or preventing possible
static charge.
If it is possible for medium to escape, e.g. through
actuating mechanisms or leaks in threaded joints,
the plant manufacturer or plant operator must take
this into consideration when dividing the area into
zones.
MCW 41 and MCW 41/4
The equipment has classification: CE Ex II 2G/D c X.
For use in potentially explosive atmospheres in
zones (surrounding atmosphere to Directive
1999/92/EC) 1, 2, 21 and 22, please read and
observe the following information:
The sign "X" in the Ex label signifies that operation
at an excessive surface temperature caused by the
medium must be avoided. The equipment itself
does not generate additional surface temperatures.
Once installed, static electricity may arise between
the equipment and the connected system. During
use in potentially explosive atmospheres, the
discharge or prevention of possible electrostatic
charging is the responsibility of the manufacturer or
owner of the system. If there is a possibility that
medium might escape, e.g. via actuating devices
or leaks in screwed couplings, the manufacturer or
owner of the system must take this into
consideration when dividing the area into zones.
If the MCW has a pneumatic drive, if incorrectly
discharged the exhaust air (compressed air)
required for operation can lead to swirls of
potentially explosive dust.
