We cover the entire electrical domain of
with our services and products.

Working for clients all over the world with strong bases in Germany and the USA.


Planning and project management of electrical and information technology systems requires great specialized knowledge and long-term experience. We work closely with our clients to come up with solutions that integrate seamlessly with existing equipment. For some clients we develop best practice standards for their manufacturing systems that are applied in their facilities worldwide. The basis for our competence is the extensive number of completed projects and knowledge of the technical developments through co-operation with vendors of current key technologies.
The basis for an effective manufacturing system and its maintenance is created by careful and extensive design and documentation. We create schematics and drawings for the assembly of electrical cabinets and junction boxes and the wiring diagrams for their installation and connection with the other components in the field. We create not only new systems but also determine the status of existing ones, making enhancements to those if necessary. EPLAN is our design system of choice when used in the automobile industry.
The software part of control systems is becoming more and more important. Programming is limited no more to mimicking the ladder logic of relay controls of the past. This realm is now embedded in a complex network of components that share data with each other. Those components include PLCs, HMIs, industrial robots, positioning systems, drives, and identification and safety systems. Depending on their complexity, extensive programming or configuration is required. In the past few years many of these components were integrated in our virtual commissioning environment. With this technology we can simulate the programs that interact with the actual machine components in our office. This leads to shorter on-site integration timelines.
Manufacturing and electrical design formed the origin of the company in the 1970s. Today we manufacture all necessary cabinets, junction boxes, operator panels and computer systems when requirements for quality and timely delivery are very high. We have all test equipment to verify the specifications and requirements by law. For regular items we use a network of specialized partners that build to our design specifications.
We take care of the quick and accurate installation of all necessary components of the manufacturing system and their interconnections. This includes the erection of the control cabinets, operator panels and junction boxes. For their connections we also make cable trays to protect and secure electrical and optical wires for energy and information transmission. Important for maintenance of the systems are wire makers and labels for identification and alerts that we also make with printing and engraving equipment.
On-site commissioning traditionally has been the most time-consuming task when implementing a new manufacturing system. With the new virtual environments that have been developed in the past few years, that is changing. Data exchange between mechanical and electrical design software and sometimes even their integration, makes this possible. We have traditionally commissioned the systems using the same people who programmed them, whenever possible. This has led to more seamless commissioning through avoiding informational separation of theoretical and actual environments. This practice will be even more important through increased offline programming and adding virtual reality to programming and commissioning in the future.
After the completion of the new production system we offer support for the client’s production and maintenance staff. Essential for a quick ramp-up is the qualification of the client’s personnel. We offer customized training programs that teach the necessary skills. This training can be held on site, in the customer’s training center, or in our own.



A new model in Volkswagen’s lineup came with the Atlas SUV, produced solely in Chattanooga. This project involved both the construction of new production lines using new equipment and programming standards, as well as integration of portions of the new model into many of the existing production lines having the ability to produce multiple models. Dressler provided engineering services in all areas of the body shop for this project, with more concentrated work in the underbody, hood, and hatch lines. The project provided excellent opportunities for company growth and reinforced the reputation of excellence.
