Complete system solutions that meet your specific requirements

Guldager produce and deliver tailor-made installations for the process industry. We design the water for the purpose you need. Whether it is for maintenance of machinery and installations in production or you have special requirements for the water involved in the production, calcium or salts in the water do not affect the final product.

Water for breweries and food industry must meet requirements for hardness, purity and much more. And the production equipment must be protected against rust and calcification so that it lasts as long as possible.

In power plants and district heating systems, food and process water can also often be kept under control in terms of the content of corrosive substances, salts and minerals.

In cooling systems water treatment is used to protect against corrosion, bacteria and fouling. Based on our many years of experience in water treatment, we have developed CatoCool, a unique concept for the treatment of cooling water systems. CatoCool is a natural alternative to a chemical-based solution.

We have the technology to deliver water with exactly the properties needed.

CASE: Completely clean water with significant savings

In the food industry there are high demands on the process water quality. In a larger slaughterhouse in Jutland, Guldager installed a number of ”UniSoft® Hydrus” softener installations to ensure clean process water without calcium.

The soft water is essential for optimal cleaning in the slaughtering process with minimum consumption. At the same time there is no deposition of calcium on tiles and equipment, which makes the cleaning easier.

The water consumption for rinsing at the slaughterhouse was high, and it was therefore crucial that the installation could reduce the consumption of salt and water for regeneration compared to traditional softening installations.

Are you experiencing any of these problems?

If the answer is yes, it is time to examine the water quality in the property. Contact us or read more about our products below.

FAQ – to the most common questions

Is corrosion protection needed today?

Yes, although most installations today are made of corrosion-resistant materials, it is still necessary to protect steel containers, sand filters, etc. In addition, tens of thousands of installations are made of galvanized steel with many years on the bag, which can last for as many years as possible with active corrosion protection.

When the hot water boiler is removed, we do not need corrosion protection?

Well, keep in mind that the piping system still needs to be protected against corrosion (Unicat).

How can softening improve the operation costs?

By avoiding lime deposits on heaters and in pumps and valves, the cost of maintenance is reduced.

Is it necessary to disinfect the boiler every year?

Yes, an annual cleaning of the boiler combined with disinfectant with chlorine dioxide is recommended as the best way to prevent Legionella.

Does corrosion protection not remove lime?

No, it only prevents corrosion, but the lime can be removed with a softening installation.
