Approved coolants
•
BASF Glysantin G30® or Valvoline Zerex G30. For other coolants, contact your local
ABB representative.
WARNING!
Do not mix different approved coolants in any conditions! Replace the
cooling liquid always with same cooling liquid! Mixing different coolant types is a
risk for cooling system corrosion.
Materials
Materials used in the internal cooling circuit are:
•
stainless steel AISI 316L (UNS 31603)
•
heavy gauge aluminum
•
plastic materials such as PA, PEX and PTFE
Note:
PVC hoses are not suitable for use with antifreeze.
•
rubber gasket NBR (nitrile rubber).
Use only these materials in the external cooling circuit, too.
WARNING!
When connecting external piping to the internal cooling circuit, use
only materials that are specified above. Copper and brass must not be used under
any circumstances. Even minor dissolution of copper can cause copper
precipitation on aluminum and subsequent galvanic corrosion. The liquid cooling system
may not contain any zinc (for example, galvanized pipes) at all since zinc would react with
the inhibitor.
