Liquid Cooling System Requirements
Proper liquid cooling is critical to frame 6L drive operation and reliability. This section provides an overview of the types of drive cooling loops, drive coolant requirements, and cooling loop connections for the
PowerFlex®
755TR liquid-cooled drive power structure.Liquid-to-Liquid Heat Exchanger Cooling Loop
The liquid-to-liquid heat exchanger uses a heat transfer plate to transfer heat from one liquid to another. This method requires a stable water supply from the user.
