  • Coolant distribution system
    Patent number: 10330405
    Abstract: A coolant distribution system uses two premixed streams of coolant at either extreme of a concentration range, and mixes these two streams in the correct percentage to obtain the desired concentration. Mixing the two streams follows a pulse width approach, and the system may use a manifold to deliver fluid to multiple machines.
