ATB Flameproof Motors

ATB NORDENHAM GmbH has decades of experience. In 1952, the first explosion-proof motors in a flameproof enclosure were manufactured under the company name, Felten & Guilleaume (F&G) at the Nordenham plant. Always aware of the market’s needs, the company started developing and designing efficient, low-noise and low-maintenance machines early on which continue to earn the respect of the professional world today. In 2002, F&G Antriebstechnik was successfully integrated in the ATB Group. Today, ATB NORDENHAM GmbH is one of the industry‘s leading suppliers. The company’s specialization in motors in a flameproof enclosure means that customers benefit from its comprehensive expertise, long-standing experience and outstanding professional competence. ATB is also a competent partner when it comes to special products such as motors with an integrated frequency inverter in a flameproof enclosure and offshore motors or water-cooled configurations. The custom design, safety and reliability of all our solutions meet the specific requirements of our customers and legal requirements.

Safe Drives for Areas with a Risk of Explosion

ATB develops, designs and manufactures drive solutions in flameproof enclosures for areas with a risk of explosion belonging to zones 1/2 (gas) and zones 21/22 (dust).
