Coolant Mixture Quality; Approved Coolants; Materials - ABB ACS880-87LC-3200A Hardware Manual

Frost protection down to
-20 °C (-4 °F)
-27 °C (-16.6 °F)
-38 °C (-36.4 °F)
-54 °C (-65.2 °F)
WARNING!
Operation at liquid temperatures below 0 °C (32 °F) is not permitted even with
antifreeze.

Coolant mixture quality

The pH level of the coolant must not be manipulated by adding chemicals not specified in
this document. This may build up sediment in the liquid.

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.
