Always healthy and clean water in the property

Residents are dependent on a good and stable water supply. For more than 70 years we have installed corrosion protection and water treatment in many properties.. Therefore we know about the challenges of residential properties and made it our specialty to deliver complete solutions, considering the entire water installation. We call it ‘Intelligent Water Treatment’.

This means that we provide both corrosion protection, softened water and bacterial prevention to a lot of our customers. In addition to delivering the installations to solve the problems, we also make sure they are operating around the clock.

At Guldager, intelligent water treatment is also effective service. And our comprehensive service program allows you to enter into a service agreement that fits your needs.

With a complete solution from Guldager, including a service agreement, we can ensure that your water installation is operating 24/7 and delivers healthy and clean water to the residents.

CASE: Investment earned in less than one year

Calcium in the hot water caused major problems with poor heat economy and calcium in perlators and on sanitation.

In a property in Copenhagen, Guldager installed a “UniSoft® Hydrus” softener in the property’s heating facility to descale the hot water for more than 400 residents. In addition to fewer problems with clogged perlators at the residents, the property achieved more than 20% savings in the heating costs.

The savings were achieved by significantly improved cooling of district heating, with a return on investment in less than a year.

FAQ – answers to the most common questions

Is corrosion protection necessary today?

Yes it is. Allthough the majority of the new installations made today are corrosion-resistant materials, it is still necessary to protect steel containers, sand filters, etc. In addition, several of the old installations are made of galvanized steel, and they will last for many years with active corrosion protection.

When the hot water boiler is removed, I guess we don't need corrosion protection?

Well, keep in mind that the piping system is still to be protected against corrosion, so you still need the corrosion protection.

How can softening improve the operation costs?

You will avoid calcium deposits on on heaters and in pumps and valves. This way you will  use less enegy heating up the system and you will reduce the maintenance costs.

Is it necessary to disinfect the boiler every year?

Yes, an annual cleaning of the boiler combined with a chlorine dioxide disinfection is recommended as the best prevention against Legionella.

Does corrosion protection remove the calcium?

No, it only prevents corrosion. But the calcium can be removed by installing a softening installation.
