Felten & Guilleaume (F&G) was the name of the company that built the first motors for hazardous atmospheres with pressure-tight encapsulation at the plant site in Nordenham back in 1952. The demand for high efficiency, low-noise and low-maintenance machines led to designs being developed at the Nordenham plant very early; they met with approval and recognition among the experts. F&G Antriebstechnik was incorporated in ATB Group in 2002.
