6. Fluids specifications
Series DX / DXS rotary joints may be used for water having the quality described below.
Other fluids including additives for the water (e.g. anticorrosion or antifreeze agents)
must be checked for compatibility with the materials used in the manufacturer's plant.
General
The quality of the water used plays a decisive role in the service life and reliability of a Maier
rotary joint. It is strongly recommended to observe the specifications listed below. Insufficient
water quality will result in heavy wear of the seal and premature failure of the rotary joint.
Section 1
Water with temperatures from 10°C to 70°C

Raw water: drinking water quality

General: clear, no sediments

Filtration: particle size 20 μ m, max. 50 μ m

Water hardness: < 3.2 mmol/l

Low salt concentration according to VdTÜV- Guideline TCh 1466 "Guideline for Circulation
Water in Hot Water and Warm Water Heating Systems" ("Richtlinie für das Kreislaufwasser
in Heißwasser – und Warmwasserheizungsanlagen), sheet 1.

If required, add a suitable antifreeze agent and a silicate-free anticorrosion agent (ensure
compatibility with the materials used in the unit, check back with manufacturer, if
necessary).
