Certified ATEX Service: Safety and performance in explosive environments

To ensure that equipment maintains its protection class after service, a technical holistic approach to the entire drivetrain is required, working strictly according to standards such as IEC/EN 60079 and our ISO 9001 quality management system.

What is required for correct ATEX service?

Not just any workshop is permitted to handle ATEX equipment. To meet international requirements, we operate based on three pillars:

• Certified workshop: The environment where the service is performed must be approved and adapted.

• Certified personnel: Technicians must have the correct specialist expertise and documented authorization to work with explosion-protected equipment.

• Strict documentation: Every step follows IEC/EN 60079 and is carefully documented to ensure the equipment remains approved after delivery.

Case: Aalestrup Elektro refurbishes agitators for a biogas plant

A current example of this precision comes from the team at Aalestrup Elektro, who recently completed an extensive renovation of a series of agitators for a biogas plant – components operating in a demanding environment where safety is business-critical. 

At first glance, the units may look modest, but they have undergone a total technical restoration to reach as-new condition:

• Component replacement: All bearings, gaskets, and seals have been replaced.

• Lubrication: New oil has been applied according to the supplier's specific requirements to minimize friction.

• Special painting: The units have been painted using a specific method and paint that meets ATEX requirements to prevent spark formation or static electricity.

Optimization of the entire drive system

Expertise within Nordic Drives Group involves more than just component-level service; it contributes to the optimization of the entire drive system. A correctly performed ATEX service ensures safety and contributes to lower energy consumption, reduced thermal load, and increased operational reliability.

In addition to our specific certifications for brands like NORD Gears and VEM, we have the expertise to perform ATEX repairs on virtually all equipment – from electric motors and gearboxes to pumps. The decisive factor is the ATEX zone in which the equipment is to be placed, as this dictates the technical requirements for the repair. By choosing a certified partner, you gain a guarantee that your facility remains safe and that your total operating costs are kept low.
