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 companys 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.
