Fan and motor manufacturer Ziehl-Abegg grew sales by 8% in 2016.
Sales rose to 482 million Euros (£415m) from 447 million Euros (£385m) in 2015.
“The pure sales figures are the one side but the other is the personal contact, talks with suppliers and customers. That is the reason why sales and service have been strengthened.
“One example of this is the opening of a branch in Dubai last year for ventilation and drive technology. We are providing more local support for our customers all over the world.”
The number of employees at Ziehl-Abegg has risen to more than 3,550 (previous year 3,450). The company traditionally publishes no information on profits.
