Our sectors and business line
Integration of control and software
HOLTEC.DK is an international expert organization, and we work daily with and for industries that need to optimize or create completely new solutions for their production. We have gained a lot of experience in integrating new equipment and software into existing productions. You therefore get a business partner who has the necessary creativity and patience to successfully reach the goal of optimizing, expanding or rebuilding your production line.
We start from your production line and workflows when we recommend and implement integration solutions of controls, software and in the composition of new hardware. It is therefore completely natural for us to act as project manager when it is relevant, so that you can spend your time on what you excel at, and we can do the same.
