ASIA WATERJET COMMISSION ATEX CERTIFIED PUMP

Asia Waterjet Equipment, the regions largest supplier to the Waterjetting industry, are proud to have delivered its first ATEX Zone 2 Certified Waterjet System.

Asia Waterjet have been supplying hydroblasting equipment for over 25years, and through doing so, have earned an unrivalled reputation for quality and excellence. “We are driven by our commitment to the industry, it is our responsibility to provide our customers with the very best tools for their job. If their job is classified as Hazardous, it is our duty to commission a Pumpset that is intrinsically safe” For intended use in potentially explosive atmospheres, Asia Waterjet Equipment can convert all of its Hydrojetting Units, electrical and diesel, to be ATEX Compliant.

What Is ATEX?

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres:
1) Directive 99/92/EC also known as ‘ATEX Workplace Directive’
2) Directive 94/9/EC also known as ‘ATEX Equipment Directive’

EX Environments become hazardous when excessive temperatures are introduced and gases, vapours or concentrations of dust in that environment are ignited. Explosions occur when non-approved electrical apparatus working in the environment fail and create open flames, static electrical discharge or sparks. When the elevation of temperature reaches the auto ignition level of the chemicals, dusts or gases being utilized, the result is an immediate explosion or fire. Explosion Proof Industrial Machines are built, tested and classified for use in EX environments. Explosion Proof Industrial Machines in static electrical conditions, vehicle turn-over or electrical failure do not produce auto igniting circumstances or temperatures. *Miretti Italia SRL
