Technical data
Coolant specification
Coolant type
Antifrogen®L (by Clariant International Ltd., www.clariant.com ) 25% or 50% water
mixture, available from Clariant distributors and ABB Service representatives.
Antifrogen®L 25% mixture is usable in storage temperatures down to -16 °C (3.2
°F). Antifrogen®L 50% mixture is usable in storage temperatures down to -40 °C (-
40 °F).
Note that operation below 0 °C (32 °F) is not allowed regardless of the freezing point
of the coolant.
WARNING!
The warranty does not cover damage occurring from use of improper
coolant.
Temperature limits
Ambient temperature: See the technical data of the drive/unit.
Freeze protection: The freezing point of the coolant is determined by the
concentration of heat transfer fluid in the mixture.
The higher the concentration of heat transfer fluid, the higher the viscosity of the
coolant. This results in a higher pressure loss in the system.
The nominal current ratings of drive system modules apply to Antifrogen®L / water
solution of 25/75 (volume). For derating with other ratios, contact your local ABB
representative.
