Clean, clear water for catering and restaurants

In cafes and restaurants, lime and minerals are a persistent problem that needs to be solved to give your guests the best possible experience.

  • Dishwashers and other expensive non-stop equipment should be protected against lime as far as possible to last for a long time and work smoothly every single day.
  • Lime and salts in the water stick to glass and service during washing if the water is not softened beforehand. This increases the workload in the kitchen.
  • Ice cubes must be clear.

All this can be done by Guldager. We have developed and supplied water treatment installations for the entire Danish catering industry for many years.


We provide and service all types of facilities that can help keep your water clean, your glasses ready and your guests happy. Call +45 48 13 44 00 and hear more.

CASE: High-end installation ensures clear dishes

No kitchen managers want to see their tunnel dishwasher break down in the midst of an important conference.

In a larger hotel in Copenhagen, Guldager has therefore installed a “UniRO 400” membrane filtration installation. Before the UniRO 400 installation, the lime is removed from the water with a “UniSoft®” softening system. With the two installations in series, Guldager always ensures lime-free and ultra clean water available for the hotel’s kitchen and various dishwashers.

The installations are installed in engineering rooms outside of the kitchen and the clean water is brought to the kitchen separately. In this way the kitchen can concentrate on the most important thing for them; to serve the customers.
