ATEX
Sikker og effektiv materialehåndtering i eksplosive miljøer med ATEX-godkendte vakuumtransportører fra Piab
Når du arbejder i potentielt eksplosive miljøer, er ATEX-certificering ikke bare en formalitet – det er en nødvendighed. ATEX (ATmosphères EXplosibles) er EU’s direktiv, der stiller krav til udstyr, som anvendes i områder med eksplosiv atmosfære. Piabs vakuumtransportører er udviklet med fuld overensstemmelse med ATEX-direktiverne og sikrer pålidelig, sikker og effektiv håndtering af pulver og granulat. Det gør dem ideelle for ingeniører og driftsansvarlige inden for fødevare-, pharma- og kemisk industri, der ønsker at minimere risiko og maksimere driftssikkerheden.
Piab's commitment to safety and legislation.
Since 2004, Piab has been a leading supplier of ATEX-certified equipment, including vacuum conveyors and machines. Our solutions are designed for the safe transport of dry powders and granules that have the potential to form explosive dust clouds. All ATEX-approved equipment is certified by third-party organisations and meets the strictest safety standards. With over 300 different configurations, we offer customised solutions for different needs.
Key features of Piab's ATEX-certified equipment
Anti-static materials
All seals, rubber parts and major plastic components are available in anti-static materials, preventing static electricity and minimising the risk of sparks and ignition.
Complete system design
Our ATEX machines come with integrated components such as vacuum pumps*, filters, inlet modules and bottom valves - a complete solution for hazardous environments.
* Vacuum conveyors with ejector pumps are ATEX approved. Mechanical pumps are not.
Industry applications
Pharmaceutical and chemical industry
When refuelling reactors in explosive environments, automatic and safe handling is essential. Piab's piFLOW®p and piFLOW®t conveyors are ATEX certified and ideal for these tasks - they are closed systems and therefore do not create danger zones during operation.
Eksplosions-risiko i fødevare industrien
In the food industry, handling ingredients such as sugar, starch, stabilisers, dextrin and flour can pose a significant explosion risk. With Piab vacuum conveyors, this risk is effectively eliminated.
Et typisk eksempel: Ingredienser tømmes fra en sækstation og føres via en vakuumtransportør til en lodret mixer med en melblanding. Herefter transporteres blandingen videre til en snegledosering – alt sammen uden støv og uden eksplosionsfare.
Our piFLOW®fc series is ideal for this type of application, offering a hygienic, dust-free and ATEX-approved solution that also meets the strict standards of the food industry.
Safe transport in the cosmetics industry
The cosmetics industry places high demands on precision and safety when handling additives such as organic thickeners, vitamin powders and sunscreens. This is where piFLOW®i and piFLOW®f from Piab are the ideal choice - they ensure gentle and efficient transport of sensitive materials without contamination.
At the same time, these vacuum conveyors are also used in the chemical industry for handling waxes, plastic powders, organic fillers, cellulose fibres and gas-filled lightweight materials - perfect for dispersing and mixing processes.
Piab in cleanroom
When installing equipment in cleanrooms, it is crucial to eliminate any risk of ignition. Piab vacuum conveyors - such as piFLOW® units - are designed with this in mind and meet the strictest ATEX requirements.
In the example shown, a piFLOW® unit fills a container (hopper). Piab ejector pumps are ATEX approved and can also be mounted externally for increased flexibility and safety. The inside of the conveyor is approved for Zone 20 or 0, while the outside is suitable for Zone 21 or 1. This ensures a holistic solution for explosive environments - even in sensitive cleanroom applications.
ATEX - Basic knowledge and certification
What is an ATEX certification?
ATEX certification is a legal requirement for equipment used in areas with a risk of explosive atmospheres. This includes environments where dust, gas, vapour or mist can form explosive mixtures. ATEX Directive 2014/34/EU defines the essential health and safety requirements for both mechanical and non-electrical equipment in hazardous zones.
Zones and equipment categories in ATEX
ATEX certification divides areas into zones based on the probability and duration of explosive atmospheres. At the same time, requirements are set for the protection level of the equipment. Piab vacuum conveyors are approved for both dust and gas zones and can also handle hybrid environmentswhere explosive mixtures of dust and gas occur - for example when transporting metal powders or pharmaceutical substances in certain gas types.
