Pneumatic offer for use in industrial and explosive atmospheres
This guide has been designed to help you quickly identify the appropriate products for your
requirements.Most of our pneumatic components are available in a standard range and a range for use
in explosive atmospheres (ATEX): this information is given in the right-hand column on each page.
Industrial range
The standard range of pneumatic components is designed to meet
requirements for industrial applications.
The operating characteristics (pressure, flow rate, service life, etc.)
have been optimised to best meet these needs.
Range for use in explosive atmospheres
The range for use in explosive atmospheres has been developed
specifically for applications requiring compliance with European
Directive 94/9/EC, the full details of which can be found on pages
30 and 31 of this guide.
The user is responsible for ensuring the compliance of his
installations. All new installations must be compliant, and
replacements in the event of breakdown or maintenance must
comply with this directive.
Characteristics of our ATEX components
v
ATEX products are specifically marked in accordance with the
latest versions of harmonised standards
v
Every product is supplied with a guide specifying the usage
restrictions in explosive atmospheres
v
A copy of the approval certificate can be provided if requested
at the time of order
v
The order entry must state the usage conditions Crouzet Control
states the usage restrictions on acknowledgements of receipt of
order, delivery notes and invoices
Crouzet Control has produced a separate catalogue
for
Pneumatic products for use in explosive atmospheres.
This catalogue gives details of the entire Crouzet Control range
of ATEX pneumatic products along with associated standards,

ATEX Directive 94/9/EC:
general information
Principles of Directive 94/9/EC:
The directive aims to harmonise the legislation of European
Union member states in order to ensure free circulation of
equipment intended for use in explosive atmospheres (gas and
dust).
Since 1 July 2003, this directive has applied to electrical, mecha-
nical, hydraulic and pneumatic products.
It concerns the assessment of protective devices and systems
(manufacturers) as well as the design (design office), installa-
tion (installers, panel-builders) and maintenance (maintenance
depts) of installations.
Application since 30 June 2003:
Manufacturers must offer products, which comply with Directive
94/9/EC and must have a Quality Control System that has been
approved by a notified body.
Users are responsible for using equipment correctly according
to the zones they have defined within their installations based
on the potential risks. Existing installations must be brought into
conformity with the ATEX Directive before 30 June 2006. All
new products commissioned must comply with Directive 94/9/
EC. In the event of breakdown, installed equipment that cannot
be repaired must be replaced with equipment complying with
Directive 94/9/EC
Definition of an explosive atmosphere:
An explosive atmosphere is defined as a mixture of flammable
substances (in the form of gas, vapour, mist or dust) with air
under atmospheric conditions in which, after ignition, combustion
spreads throughout the entire unburned mixture.
Sparks
Heat source
Classification:
Potentially explosive environments are classified by zone in
compliance with Directive 1999/92/EC. This directive is aimed
at users. It details the minimum requirements for increasing
protection of the health and safety of workers exposed to
explosive atmospheres.
ATEX Directive 94/9/EC defines categories of equipment and
protection systems, which can be used in the corresponding
zones.
Categories M1 and M2 relate to mines (group I)
Categories 1, 2 and 3 relate to other locations (group II)
often referred to as "Surface industries"
Documents and recommendations/products:
ATEX-certified products must be supplied with an EC declaration
of conformity and a user manual.
At the time of sale, the sales representatives must check the zone
in which the product is to be used. On the order, the customer
must inform the manufacturer of the conditions of use.
Manufacturers and distributors must ensure that their sales of
ATEX products are traceable (so that customers who have been
sold an ATEX product can be located in relation to the product's
date of manufacture).
In the case of an assembly, the product with the lowest certifica-
tion level determines the level of the whole assembly.
Silos
Oxidiser
Oxygen (air contains
21% oxygen)
Fuel
Flammable substances in the
form of gas, vapour, mist, dust
Some relevant areas:
Water treatment
Refineries
Paper industry
Gas storage
Paint factories
Vehicles
