Fitness clubs

The Merus ring offers an easy-to-install and sustainable solution for problems with water for many types of buildings, including a large amount of fitness clubs all over Europe. Apart from being able to make use of the gym machines in fitness clubs, gym members can usually also make use of several other facilities, including the possibility to shower and occasionally also other amenities, such as spas, steam baths, saunas or even pools.

After providing several clubs with demo-installations to experience the results, the Merus ring has now been installed in over 450 fitness clubs of Basic Fit, Fitness First and Health City. These are not only installed in the Netherlands, yet as well in Belgium, Luxembourg, France and Spain and there are still many more to come. The rings are mainly installed with the purpose of reducing lime scale, which makes it much easier for gym clubs to keep their facilities as clean and hygienic as possible.





Which amenities in a fitness club can benefit from the Merus technology?

The biggest issue which fitness clubs encounter is the presence of lime scale in shower areas, which indicates the overall hygiene of a club and can affect the satisfaction of gym members. A shower head covered with lime scale usually results in water going in all directions. Secondly, steam generators, which produce steam for baths, can also suffer from this problem with lime scale, often found in the nozzles.

Where would the Merus rings be installed?

Depending on the size of the fitness club, 2-3 rings would have to be installed; one at the inlet of the city water into the club and the other one at the hot water boiler. If there is a steam generator or another similar device too, another Merus ring would be installed at the feed water line.

What is the result?

All fitness clubs equipped with Merus rings can conclude that the technology ensures less forming of lime scale and that the remaining amount is very soft and therefore easy to remove. Some fitness clubs used to clean e.g. the steam generator twice a week, which does not only cost much money, it also takes a large amount of time from employees. Thanks to this sustainable and innovative solution, a special technician will no longer be necessary and the task can be seen as a ‘side job’ for employees. Where the usual solution used to be a classical water softener, the investment in Merus has proved itself with a significant decrease in service and labor costs and incredible results.

Fitness First: Letter of Recommendation

Dear Sir,

We would like to take the opportunity and hereby thank you for installing the MERUS rings which we are going to recommend without any doubt. Our equipment such as the steam generators for the steam room as well as all the pipes suffered from heavy lime scale even though we did use water softeners. We had to clean and treat the equipment with corrosive chemicals on a regular basis and sometimes were left with no choice other than to completely change the elements in question. We have tested the MERUS rings at 3 of our clubs (at one new one and 2 old ones) and could immediately recognize a drop in failures and symptoms relating to the presence of limestone.

The easiness (the rings are adjustable for all types and sizes of pipes), the fast installation and efficiency of the MERUS rings after only a short time (results are visible in less than 2 months) are big assets; moreover the rings do not need any special maintenance unlike other methods for the conventional water treatment.
We have therefore decided to introduce and install MERUS rings at all our clubs and would like to do so in cooperation with you.
