3.7 Water quality

Lindab recommend water treatment and quality to be
according to VDI 2035-2.
• The water preparation and maintenance for the chilled
beam water circuit must 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 must be oxygen free, to prevent corrosion.
• The water system must be filled with potable water
that complies with the "EC directive 98/83/EC".
• pH value of water must be between approximately
6-9 pH.
• The water velocities should not exceed 1m/s, and
should be kept as close to the nominal flow as
possible to minimize noise and optimize the energy
yield.
• Use in-line strainers to remove dirt particles from the
water.
• If the water contains any additive inhibitor, then it
must be appropriate to use with copper and solder.

3.8 Air quality

Primary supply air have to be clean, dry and filtered
before reaching the beam.

3.9 Capacity test
