For small applications (e.g. private homes up to 6 apartments) usually one Merus Ring is sufficient. It is installed at the main water line in the basement.
The smaller Merus Rings (3/4“, 1“, 1 1/4“) have a capacity of 12m³ per day – this equals the maximum water consumption of 20 persons.
For industrial application we have special Merus Rings for higher flow rates. We have made successful installations with a flow volume of more than 10,000 m³ per hour.
