Three-phase electric motors suitable to be used in potentially explosive atmospheres with the presence of gas, combustible gas or mist. where after ignition has occurred, combustion spreads to the entire unburned mixture.
Directive 1999/92/CE gives details on the ‘Division and definition of zones where explosive atmosphere might occur’.
Neri Motori produces ATEX motors for the following Zones:
An area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time.
Note: This area may also include areas close to Zone 0 or 1.
A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only
Note: This area may also include areas close to equipment, protective systems and components containing powder that might come out from the containers due to loss and form powder deposits (e.g. ground salt that comes out from the mills and might deposit its powder).
