Our sites

Located in the Southern Palatinate

Landau in der Pfalz

Where COMPREX® is made

In our technical centre in Landau we’re working on further development of our technology. Here, hardware and software are merged to form our unique COMPREX® technology. In Landau we develop the control software and install the technical equipment in the COMPREX® units.

Workshop and vehicle construction

In addition to our tool and storage halls, we also own a fully equipped metal construction and carpentry workshop. Thus development, care and maintenance of our own technology and our vehicles is carried out by our development and service team on site.

Short distances

Besides space for our COMPREX® fleet, the office of our project engineering team is located in Landau. From pre-planning to post-processing of operations, every step is done on site. These short distances enable us to make precise arrangements and coordination.

Our test facility

A special feature: our own test rig. Here, the effectiveness of our COMPREX® technology is tested on a regular basis. We would be pleased to demonstrate the power of COMPREX® to you during a visit in our technical centre. Feel free to contact us for live-experience in Landau.

Administration and organization

The headquarters of the management and the administration of HAMMANN GmbH are located in Annweiler. Here our colleagues in the administration and sales departments are receiving your enquiries and plan the organisation of assignments, while the field service is organised decentrally throughout Germany.

Technical bases

Organised decentrally

In Domnitz, Salzwedel and Neunkirchen, we have established three further regional bases which enable us to act flexibly on a local level. In order to be able to organize the project assignments perfectly and to be able to prepare and follow up quickly, our employees on site have their own vehicle combinations as well as all technical equipment.
