Food manufacturing plants take raw agricultural products such as grains and turn them into ingredients for items such as bread and milk powder. Working with these tiny food substances causes dust to accumulate in the workshop, outlining a need for dust collectors. These collectors are required for various reasons such as to stop the cross contamination of foods (especially those that are known allergens), to lessen slippery floors and surfaces, and also to eliminate the inhalation of hazardous, airborne dust particles.

These small grain particles collect within the dust collector and if combined with static electricity can be a source of ignition. If a dust collector does ignite, this can cause extensive damage to property, other machinery and most importantly, can harm and even fatally injure those working on the premises. This is why dust collectors need to be ATEX certified.

What Is An ATEX Certificate?

Firstly, ATEX stands for ATmospheres EXplosible, and refers to the hazardous or potentially explosive properties of both gaseous and dusty environments such as saw mills, food processing plants and flour mills. An ATEX certificate is a European certificate awarded to machinery and equipment that has been proved to be intrinsically safe. This piece of machinery or equipment, if awarded this certificate, is safe to use within hazardous or explosive environments. If a piece of machinery is used within a highly explosive environment, and does not have an ATEX certificate, the chances are that should an ignition occur, extensive damage will be done.

Why Should A Dust Collector be ATEX Certified?

The particles that are eliminated by a dust collector, as in a food processing plant, can accumulate inside the dust collector, and should a single spark occur could lead to an explosion. An ATEX certified dust collector has been designed to contain, expel and prevent an explosion from spreading. This limits the amount of additional damage that could occur, should there be no safety processes in place.

Nederman ATEX approved dust collectors, available from Envirox, are designed to handle an explosion in a controlled manner. The Nederman CARZ valve together with an ATEX dust collector, prevents explosions from spreading through the ducting system, causing immense damage, and human injuries and fatalities. When purchasing a dust collector, it is imperative that it is ATEX approved.

Nederman offers dust collector ranges suitable for various industries, including food processing, and most importantly are ATEX certified.

Nederman dust collectors suitable for the food processing plants include:

  • The Nederman FMCZ, developed to capture and filter dry dust fumes suitable for removing harmful fine dusts and fumes. It incorporates the patented Nederman UniClean cartridge technology for maximum cleaning and an extended lifespan.
  • The Nederman AUTO-MZ, a free-standing filter suitable for non-continuous duty during various industrial and commercial applications that expel light to medium volumes of dry dust.
  • The Nederman MJC Mini Ex, used for light to medium volumes of dry dust is developed for continuous use. It also includes the Nederman UniClean cartridge technology.
  • Nederman CARZ valves, explosion pressure resistance equipment that prevents an explosion moving from the filter to the workplace.
