Approved fluids
Heating water (as per VDI 2035/VdTÜV Tch 1466)
Water/glycol mixtures, max. mixing ratio 1:1 (for mixtures
with glycol the conveying data of the pump should be cor-
rected to those for the higher viscosity, depending on the
percentage mixing ratio)
Only use brand-name goods with corrosion protection inhibi-
tors; comply with the manufacturer's specifications and safety
data sheets.
The pump manufacturer's approval must be obtained for
the use of other fluids.
Ethylene/propylene glycol with corrosion inhibitors.
No oxygen binding agents, no chemical sealants (ensure
enclosed system from corrosion perspective according to
VDI 2035; rework leaky points).
Commercially available anti-corrosion agents

without cor-
rosive anodic inhibitors (e.g. underdosing due to consump-
tion).
Commercially available combination products

without inor-
ganic or polymer film formers.
