Company history and international cooperation

Throughout a century, Guldager A/S has been working with water. We are one of Europes oldest water treatment companies, but that does not mean we are resting on laurels. A hundred years ago, we were at the forefront of technological development – and we still are. Every time we learn something new, it offers new opportunities for new products and solutions.

Our story started in 1923 when Alfred Guldager invented electrolysis. A method of protecting water pipes from corrosion. It is the method that today is standard over most of the world. Over the years, we have expanded our business areas considerably. In addition to corrosion protection of water installations, we are currently developing solutions for desalination, softening, bacterial protection and much more.

We continuously develop our technologies and combine and customize them so that we achieve the very best operating benefits – for the benefit of our customers. We strive to be a reliable and competent advisor every day, and – in combination with a strong service organization – we ensure that our customers installations always work optimally.
