Even though the battery of the chilled beam can withstand a very high static
working pressure, we recommend a much lower dynamic working pressure, to
avoid noise issues from the valves.

–
The water preparation and maintenance for the chilled beam water circuit should
be handled by a specialist
–
To prevent corrosion, the water circuit must be airtight
–
The water system must also be equipped with aerators to remove any build-up air
in the system.
–
The water should be oxygen free, to prevent corrosion.
–
The water system must be filled with potable water that complies with the "EC
directive 98/83/EC".
