ATEX & Hazardous-Area Expertise
Technical expertise and proven CompEX competence for working in ATEX classified areas.
Check security.
Reduce risk in ATEX environments.
Cetec Energy provides technical advice, documentation and supervision in facilities with potentially explosive atmospheres. The services include establishing and updating ATEX classification as well as technical review and verification of installations in zoned areas.
The work is carried out with in-depth knowledge of electrical installations in process plants and with a focus on the actual execution of the installation - not just the document basis.
Classification and technical structure of hazardous areas
Correct zone classification and structured ATEX documentation is a prerequisite for safe operation in petrochemical plants and other process environments.
Cetec Energy supports:
- Creating and updating zone classification
- Review of existing ATEX documentation
- Assessment of installation practices in relation to classification
- Identifying discrepancies between documentation and actual execution
- Structuring ATEX governance in your organisation
Our efforts are based on the specific structure and history of the installation, including older panels and components where changes over time can affect the classification.
Technical verification and advice on equipment in Ex installations
ATEX environments require precise execution and correct equipment selection. Cetec Energy carries out both technical verification of ATEX environments as well as advice on and inspection of proper equipment in ATEX zones.
The review is conducted by experienced technicians and supervisors, with CompEx training and extensive knowledge of practical conditions and risk factors. At Cetec Energy, we focus on the actual condition of the installation and identify issues that may affect safety and compliance.
- Correct labelling and equipment selection according to zone
- Enclosure grades, seals and cable entries
- Protection principles and installation details
- Compliance with relevant standards
We regularly find that in some installations, the ATEX documentation is updated, while the installation has changed over time.
In this case, compliance only applies on paper - not in the real world where employees need to be able to go to work safely.
Here, our work starts with the actual execution - panels, components and classification - and then ensures that documentation and reality match.
This gives our customers a technically sound basis for both operations and further decisions.

Supervision and certified competence in ATEX areas
Working in potentially explosive atmospheres requires proven and relevant competence.
Cetec Energy provides personnel with experience from classified installations and with certifications, including CompEx, where tasks require documented qualification to work in ATEX zones.
Supervision and technical sparring is provided in connection with:
- Modifications and retrofit in zoned areas
- Commissioning of Ex installations
- Updating documentation when changes are made
- Integration of new components in existing zones
This expertise is combined with practical experience from electrical installations in operation, ensuring correct execution and documentation in accordance with applicable requirements.

Yaw Ring Repair
Yaw ring repair becomes relevant when damaged teeth on a yaw ring affect the wind turbine's ability to turn the nacelle correctly towards the windthe.
The challenge
Worn and broken teeth on the yaw ring can lead to misalignment, increased stress on the drive system and, in the worst case, downtime.
The traditional solution is often to replace the entire yaw ring. This typically requires a crane, longer downtime and significant costs for spare parts, planning and external equipment.
The alternative
At Cetec Energy, we perform yaw ring repair on the uptower. This means that the repair can be carried out directly in the wind turbine without full disassembly of the nacelle.
Using a specialised and proven procedure, the damaged teeth are milled, welded and restored so that the tooth profile again matches the required geometry. The work is carried out with a focus on quality, documentation and reliability.
The result
The method brings the workshop's competences uptower in the wind turbine. For the operator, this means shorter downtime, lower overall costs and a more controlled process than a full replacement.
This type of yaw ring repair can extend the life of a critical component and get the turbine back in production within days - not weeks.
Trusted specialists in the energy sector
This expertise is combined with practical experience from electrical installations in operation, ensuring correct execution and documentation in accordance with applicable requirements.
Proven safety and regulatory compliance
ATEX work requires consistency between classification, installation and documentation. The result is a structured and technically sound approach to hazardous areas that reduces risk and supports stable operation.
Cetec Energy ensures that:
- Classification and installation match
- Changes are registered and documented correctly
- Deviations are identified and handled systematically
- The organisation has an updated and usable documentation base
