At the beginning of March, the head office of Boltjes Serial Production relocated to the beautiful town of Deventer, the history of which dates back to the 8th century. The most important local employer and also a client of ours is Nefit, a producer of heating systems. The original head office of our Dutch company was located in Amersfoort before moving to Ermel for the last 17 years. You can see from the photos the passing of time and how our offices have changed.
