ATEX Zone KITO Explosion Proof Hoist Supplier

ATEX lifting equipment can mean electric chain hoists, wire rope hoists and belt hoists, winches, trolleys and pneumatic lifting equipment, and can be referred to as spark proof or Ex equipment.

WHAT IS ATEX ZONE?

ATEX zones for dustsDust clouds in the explosive region (above the minimum explosible concentration) are categorised into 3 zones, based upon the grade of release (as per EN60079-10-2:2009):

Zone 20

Continuous release inside a dust containment enclosure gives rise to Zone 20 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is present continuously, or for long periods or frequently for short periods. For example, a mill or pneumatic conveying system.

Zone 21

Primary grade of release gives rise to Zone 21 - a place in which an explosive atmosphere, in the form of a cloud of combustible dust in air, is likely to occur occasionally in normal operation. For example, bagging points and inspection ports that are frequently opened.

Zone 22

Secondary grade of release gives rise to Zone 22 - 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. For example, leaks from incorrectly fitted lids or spillages.

In the food industry, there are places like flour mills that often have explosible dusts present. Examples of explosible dusts in the food industry include custard powder, instant coffee, sugar, dried milk, potato powder, and soup powder. These substances, when finely ground, may ignite more easily or with lower energy. The main concern in the food industry is that if any combustible substance is mixed or suspended in the air at the right concentrations and contained in a building or vessel, it can result in a violent explosion when ignited by a spark.

Within any ATEX rated zone there is significant importance placed on safety and the necessity of spark proof/explosion proof hoists and lifting equipment is paramount.
