Thinking is our craft.

HESOTECH GmbH automatisieren – visualisieren in Diez was founded in 1994 by Dr. Roland Sonnenschein, who is still the managing director. As a service provider, the company creates individual software solutions for technical systems to solve complex problems in the areas of automation (recording, control and regulation of technical processes), documentation (recording, processing and administration of measured values) and visualization (graphical representation of evaluations).

We are experts in overcoming barriers of heterogeneous interfaces: The systems and machines involved in a value chain produce a multitude of different information and data types (from numbers to images). In order to be able to exploit the potential of all the data, the different data of the various systems and machines must be efficiently and reliably combined and linked in a holistic database (“Industry 4.0”). Many global players rely on software from HESOTECH GmbH in critical areas of their manufacturing processes.
