In 1963 Ampulz was formed as a division of Holec in Hengelo, The Netherlands
In 1999 the division was taken over by the company Vonk, and moved to Coevorden.
After being aquired by Internatio-Muller, Vonk became a division of Imtech NV.
Imtech Industry International B.V. is acquired by Techim B.V. and becomes Industry International B.V. where Ampulz is one of the Business Units.
Effective from the end of 2016, each of the Industry International business units gets an own brand name, to serve the market with more focus on the main activity of the company: providing complex power conversion solutions and services to a range of industries.
