Explosion Proof Centrifugal Fan – ATEX & IECEx Certified for Hazardous Areas
Engineering & Application Overview
The fan used in a classified hazard area like oil and gas plants, petrochemical factories, solvent-based paint and coating lines, LNG terminals, pharmaceutical production and wastewater treatment works is not the same as a standard centrifugal fan. Those facilities have to face a legal and physical risk that can't manage a standard centrifugal fan. During a normal plant operation those flammable gases, solvent vapors, and combustible dust create explosive atmospheres in (Zone 1) and (Zone 2) gas fields. Can you imagine that during this operation, if any bearing exceeds its temperature class, a shaft seal fails and exposes hot surfaces, a small arc or spark is generated inside the standard terminal box of the motor or any small fault is enough to bring a disaster or full-scale explosion in the (zone1) environment. For these reasons ATEX Directive 2014/34/EU makes certified explosion protection mandatory for all the equipment installed in these zones without any concessions. Without an ATEX and IECEx certified fan is not only taking technical or engineering risks, rather it may impact entire factory insurances. Even plant managers have to face direct legal and criminal liability and may also lose all the legal defense after an accident.
Our Explosion Proof Centrifugal Fan is dually certified under ATEX - EU Directive 2014/34/EU and IECEx international explosive atmosphere standards. It also obtained independent certification from TÜV as a notified body and obtained CITC certification from Chinese national GB. This fan is especially rated for completely safe use in (Zone 1) and (Zone 2) gas-hazardous areas and (Zone 21 / Zone 22) combustible dust zones. Motor protection covers ExD IIB T4 for ethylene-group hydrocarbon environments and ExD IIC T4 for hydrogen and acetylene, which is the most stringent gas group classification. It also complies with the EN 14986:2017 standard, which is a specific European standard for fan design in potentially explosive atmospheres. Which covers non-sparking impeller-to-housing clearances, shaft seal integrity, earthing and bonding continuity and maximum allowable surface temperature control at each operating point.
The Explosion Proof Centrifugal Fan is listed on our Y-Series category. It delivers high efficiency and ensure full hazardous area compliance (ATEX/IECEx). It can deliver up to 300,000 m³/h airflow and up to 29,800 Pa static pressure. Every unit is available with an ExE motor configuration and also provides a complete ATEX/IECEx Declaration of Conformity and full Ex marking documentation.
