For nearly a century, Guldager A/S has worked with water. We are one of Europe's oldest water treatment companies, but that does not mean we rest on our laurels. A hundred years ago, we were already at the forefront of technological development – and we still are. Every time we learn something new, it opens up possibilities for new products and solutions, and it has actually always been that way at Guldager.
Our history began in 1923 when Alfred Guldager conceived the idea of using electrolysis as a method to protect water pipes against corrosion. Today, this method is standard across most of the world. Over the years, we have significantly expanded our business areas. In addition to corrosion protection for water installations, we currently develop solutions for desalination, softening, bacterial protection, and much more.
We continuously develop our technologies, combining and adapting them to achieve optimal operational benefits – for the advantage of our customers. We strive every day to be a reliable and competent advisor, and combined with a strong service organization, we ensure that our customers' Guldager installations always operate at peak performance.
