Clean, clear water for catering and restaurants

In cafés and restaurants, lime and minerals are an ongoing problem that needs to be addressed. So you can give your guests the best possible experience.

  • Dishwashers and other expensive equipment that run non-stop need the best possible protection from limescale to ensure they last and run smoothly every day.
  • Lime and salts in the water will stick to glassware and tableware during washing if the water is not softened beforehand. This increases the amount of work in the kitchen.
  • Isterisations must be clear.

Guldager can help with all this. We have developed and supplied water treatment systems to the entire Danish restaurant industry for many years.

Treated water provides the best results and benefits for you!

Your guests should have the best experience when they visit you. Even the basics like cutlery, crockery and glassware need to be sparkling clean, of course. Danish water contains lime and minerals, which cause problems for dishwashers, steam ovens and other expensive equipment. With treated water you ensure

  • perfect washing up without the need for rinsing
  • less consumption of soap and detergents
  • longer life of machines and possibly longer intervals between services
  • perfect coffee and clear ice cubes in drinks

With Guldager's new range of filters and dedicated RO systems for dishwashers, we can meet your needs 100%.

We supply and service all types of equipment to help you keep your water clean, your glasses clear and your guests happy. Call us on +45 48 13 44 00 to find out more.

Tunnel dishwasher-in-restaurant

CASE: State-of-the-art installation ensures clear dishes

No chef wants to see his tunnel dishwasher break down in the middle of an important conference.

Guldager has therefore installed a "UniRO 400" membrane filtration system at a major hotel in Copenhagen. Before the installation, the lime is removed from the water with a "UniSoft®" softening installation. With the two plants in series, Guldager ensures that lime-free and ultra-pure water is always available for the hotel's kitchen and various dishwashers.

The systems are installed in technical rooms outside the kitchen and the clean water is supplied to the kitchen separately. This allows the kitchen to concentrate on what is most important to them; serving customers.
