ATEX fans for flammable gases and/or operation in Ex environments. If flammable gases, vapours or dusts are present in or around the fan, special measures must be taken to avoid any ignition hazards.
Fans for such applications must be designed, manufactured and tested according to special standards.
Standard EN 60079-0:2014 distinguishes between Group I for gases and dusts used in mining applications and Group II for gases and dusts used in other applications with subgroups IIA (e.g. petrol, methane), IIB (e.g. hydrogen sulphide) and IIC (e.g. H2, acetylene).
Meidinger has many years of experience in the construction of ATEX fans for groups II.
In Europe, the operator defines the Ex zone applicable to their application according to EU Directive 1999/92/EC (formerly ATEX137, Operator Directive). The equipment manufacturer builds its equipment according to the equipment category defined, inter alia, in EU Directive 2014/34/EC (formerly94/9/EC’ ATEX Directive).
Outside Europe, the EPL marking (Explosion Protection Level) according to EN/IEC 60079-0 is often indicated instead of the equipment category according to ATEX.
Meidinger offers a wide range of models for Ex zones
2,1 and even for zone 0.
For the production of Category 1G fans (Zone 0 fans), Meidinger is subject to regular certification by a notified body of the EU.
