Material Used as Description
Zinc Pipes, valves and
󹪝ttings
Use is not permitted.
Brass Pipes, valves and
󹪝ttings
Can be used in closed circuits with inhibitor.
Copper Pipes, valves and
󹪝ttings
Can be used only in closed circuits with inhibitors in which the heat
sink and copper component are separated (e.g. connection hose
on devices).
Common steel (e.g. St37) Pipes Permissible in closed circuits and semi-open circuits with inhibitors
or Antifrogen N, check for oxide formation, inspection window
recommended.
Cast steel, cast iron Pipes, motors Closed circuit and use of strainers and 󹪞ushback 󹪝lters. Fe separator
for stainless heat sink.
High-alloy steel, Group 1 (V2A) Pipes, valves and
󹪝ttings
Can be used for drinking or municipal water with a chloride content
up to <250ppm, suitable according to de󹪝nition in Section "Cool‐
ant de󹪝nition".
High-alloy steel, Group 2 (V4A) Pipes, valves and
󹪝ttings
Can be used for drinking or municipal water with a chloride content
up to <500ppm, suitable according to de󹪝nition in Section "Cool‐
ant de󹪝nition".
ABS (AcrylnitrileButadieneStyrene) Pipes, valves and
󹪝ttings
Suitable according to the de󹪝nition in Section "Coolant de󹪝nition".
Suitable for mixing with inhibitor and/or biocide as well as Antifro‐
gen N.
Installation comprising di󹪜erent ma‐
terials (mixed installation)
