EXPLOSION PROOF MOTOR WITH PRESSURIZATION SYSTEM
In August 2016 Cantoni Group delivered Explosion Proof Motor with Pressurization System to SIAD Macchine Impianti S.p.A.
The motor delivered to SIAD Macchine Impianti S.p.A. is Medium Voltage Explosion Proof Motor with Pressurization System.
The principle of a pressurized apparatus
Ingress of a flammable gases is prevented by maintaining a protective gas, inside the enclosure, at a higher
pressure than the surrounding atmosphere. As long as this positive pressure is maintained, no gas (or even dust) will be able to enter the enclosure. Motor's housing is purged prior to pressurization in order to ensure that potentially explosive gases do not occur in the housing.
The motor is equipped with certified system which is responsible for purging process and for creating and maintaining positive pressure inside motors housing. In case purging cycle is not completed or if the enclosure pressure drops below the specified pressure the motor will not be energized.
