Preventing this risk requires controlling the formation of **explosive atmospheres (ATEX)** and choosing **certified equipment** right from the design stage of production processes. In this guide, discover why and how **ATEX-certified pneumatic motors** are becoming the safest and most efficient alternative to electric motors in hazardous environments.     ![thumbnail_Pop up HL83C](https://blog.modec.fr/hs-fs/hubfs/thumbnail_Pop%20up%20HL83C.png?width=452&height=370&name=thumbnail_Pop%20up%20HL83C.png) ## Electric Motors in Industry: Versatile but Risky in ATEX Zones ### What is an Electric Motor? An **electric motor** converts electromagnetic energy into mechanical energy. They are widely used in industry (pumps, conveyors, fans) and come in multiple sizes and configurations. However, their use in **explosive atmospheres** poses major challenges. ### Limitations and Risks of Electric Motors in Explosive Atmospheres - **Spark hazards** during start-up or insulation failure - **Overheating risks** that can ignite gases or dust - **Sensitivity to harsh environments** (dust, humidity, high temperatures, electromagnetic fields) - **Complexity and cost** of ATEX-compliant control and protection systems - **High maintenance and inspection costs** to maintain certification - **Potential accidents**: fires, explosions, electrocution ## What is ATEX? An **ATEX (ATmosphères EXplosibles)** is a mixture of air and flammable substances (gas, vapors, dust) that may ignite upon contact with a spark or hot surface. Examples include: - **Gases:** methane, propane, hydrogen - **Vapors:** ethanol, acetone - **Dust:** aluminum, grain, coal ### Regulatory Framework In the EU, equipment must comply with [**Directive 2014/34/EU**](https://eur-lex.europa.eu/eli/dir/2014/34/oj/eng) and the **Machinery Directive 2006/42/EC**, ensuring it meets strict safety requirements for explosive atmospheres.   ![air motors-1](https://blog.modec.fr/hs-fs/hubfs/air%20motors-1.png?width=507&height=289&name=air%20motors-1.png)[![Download the air motor handbook](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/1845083/29b09523-90e2-48bd-a5e2-5f27c4df8a50.png)](https://hubspot-cta-redirect-eu1-prod.s3.amazonaws.com/cta/redirect/1845083/29b09523-90e2-48bd-a5e2-5f27c4df8a50) ## Pneumatic Motors: A Naturally Safe Solution ### What is a Pneumatic Motor? A **pneumatic motor** uses compressed air expansion to generate mechanical power. This technology is valued for its **safety, simplicity, and reliability** in industrial settings. ### ATEX Certification Pneumatic motors can be designed and tested to **meet ATEX certification**, ensuring safe use even in explosive environments.   ## Advantages of ATEX Pneumatic Motors over Electric Motors - **No spark risk**: no electrical components to ignite flammable gases - **Self-cooling effect**: air expansion cools the motor during operation - **Simple and cost-effective**: no complex wiring or expensive protective devices - **Reliable in extreme conditions**: resistant to dust, humidity, and high heat - **Multi-industry compatibility**: oil & gas, food processing, water treatment, chemical plants, mining ## Comparison: Electric vs. Pneumatic Motors in ATEX Zones | Criteria | Electric Motor | Pneumatic Motor (ATEX) | | --- | --- | --- | | **Spark risk** | High (electrical arcs) | None (no electricity) | | **Overheating** | Possible, needs control | Self-cooling with air | | **Complexity of compliance** | High (wiring, shielding) | Low (air network is safe) | | **Maintenance costs** | High | Low | | **Suitability in harsh environments** | Limited (dust, moisture) | Excellent (robust design) | | **Energy source** | Electricity | Compressed air | | **Cost to achieve ATEX compliance** | High | Moderate/Low | ## Why Choose Pneumatic Technology in Explosive Zones? Making an entire electrical installation ATEX-compliant can be **complex and expensive** (special cabling, protective enclosures, periodic inspections). By contrast, an **air network is inherently safe**: even in case of leaks or ruptures, there is no risk of sparks or ignition. --- ## MODEC Expertise: Certified Pneumatic Motors for Hazardous Industries Modec designs and manufactures **ATEX-certified pneumatic motors** tailored to the most demanding industrial environments.
