Explosion Proof Actuator

ATEX actuators are designed to be used in hazardous environments. ATEX stands for “Atmospheric Explosion-Proof Equipment” and is an EU directive that regulates the manufacture of equipment used in potentially explosive atmospheres.

Our ATEX linear actuators are ideal for use in gas and dust applications. They are rated for Class I, Division 1, Groups B, C and D. They have a unique design that eliminates multiple potential leak points.
ATEX Approval

ATEX approval is the process of verifying that equipment or protective systems are suitable for use in potentially explosive atmospheres. The European Union’s ATEX Directives (2014/34/EU and 99/92/EC) define the minimum safety requirements for equipment and workplaces that operate in such environments.

Whether your equipment needs to be ATEX certified or you need help creating an ATEX Compliance Checklist, TUV SUD can assist. Our experts can support you in classifying your products according to the ATEX 2014/34/EU directive or other classification requirements such as those found in the IECEx certification scheme.

For example, IPU engine starting systems for FSVs, underground rail systems and marine applications are required to be ATEX approved. Similarly, IECEx approval is an international standard for electrical equipment used in hazardous areas. Both IECEx and ATEX certification require the use of recognised standards and evaluation by a Notified Body. But the main difference is that ATEX is only recognised within the EU while IECEx is globally accepted.
ATEX Certification

ATEX certification is mandatory for equipment and protective systems used in zones where flammable gases, vapors, or dusts may exist. The European Union created the ATEX directive in the aftermath of the 2010 oil spill that crippled Deepwater Horizon and sent millions of barrels of oil into the Gulf of Mexico.

While ATEX is driven by European regulations and laws, it uses internationally harmonised standards. The ATEX certification process differs from UL or IECEx, so be sure you understand which one your product needs.

Becoming ATEX certified requires meeting technical specifications and health and safety requirements. Once you pass a rigorous test, your products can bear the CE mark—a self-declaration that says your equipment meets ATEX requirements. This can be particularly important if you sell to customers in Europe. Having your company’s equipment ATEX certified can help you expand into new markets. The ATEX certification process also helps improve your company’s brand identity and customer trust.
ATEX Design

As an engineer, a basic understanding of ATEX standards is important. But it is not enough to just purchase an ATEX component and bolt it on. It is essential that ATEX is considered from the very beginning of the design process, so that any required intrinsic safety features can be built in.

This is because the ATEX Directives (formerly known as the Product Directive 94/9/EC and the Explosive Atmospheres Directive) detail minimum requirements for equipment to be used in hazardous environments. These are often environments where the risk of a fire or explosion is higher than in normal operation and may include flammable gases, vapors or dust.

The ATEX Directives specify the constructional requirements for equipment used in potentially explosive atmospheres and detail the procedures and equipment to be used in these zones. They also require the classification of workplaces and a permit to work scheme. This process requires niche technical expertise and a significant time commitment.
ATEX Installation

When installing equipment in potentially explosive areas, it is important to consider safety factors. The ATEX directive (94/9/EC + 99/92/CE) covers a wide range of equipment including machinery, components and protective systems. This includes items that are not intrinsically safe, but require a level of protection to ensure safety in case of abnormal operation or unexpected operational disturbances.

ATEX Zone classifications are based on two fundamental criteria: the type of substance that can cause an explosive atmosphere (gas, steam, fog, or dust) and its frequency and duration. The ATEX equipment must be specifically designed for each of these zones, and it must carry the appropriate ATEX symbol to identify itself as safe in that environment.

Keeping track of all these regulations is critical to maintaining compliance. Using a low-code platform like DATAMYTE, you can quickly build an ATEX Compliance Checklist to ensure your business is meeting all industry standards. The system will automatically log and record risk assessments, area classifications, equipment certifications, installation activities, maintenance, training and more.Explosion Proof Actuator ATEX
