ATEX Zones 21 and 22 are specific to hazardous dust environments, like can be found in the food industry in, for example, a flour mill where explosible dusts are often present. Some examples of explosible dusts within the food industry alongside flour are custard powder, instant coffee, sugar, dried milk, potato powder and soup powder as a solid substance that is finely ground may ignite more.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.Zone 20: Dust cloud likely to be present continuously or for long periods: Zone 21: Dust cloud likely to be present occasionally in normal operation: Zone 22: Dust cloud unlikely to occur in normal operation, but if it does, will only exist for a short period.


The range of Ex d flameproof line heaters are suitable for heating all process fluids which are non-corrosive to the materials of construction, providing a clean and efficient heating method for bulk liquid flow applications. The Ex d flameproof line heater range is certified for use in hazardous areas where the atmosphere is classified as a Zone 1 or 2 (IIA, IIB, IIC) gas group, or a Zone 21.Titan IIIB was the collective name for a number of derivatives of the Titan II ICBM and Titan III launch vehicle, modified by the addition of an Agena upper stage. It consisted of four separate rockets. The Titan 23B was a basic Titan II with an Agena upper stage, and the Titan 24B was the same concept, but using the slightly enlarged Titan IIIM rocket as the base.
