1. A pumping system, comprising:

  • a thermal sub-cooling device comprising a cooled portion and a heated portion;

    a pump having an inlet and an outlet, the inlet configured to receive sub-cooled fluid cooled by the cooled portion of the thermal sub-cooling device; and

    a controller to execute a start-up procedure, the start-up procedure comprising instructions for;

    gathering input to determine risk for pump cavitation; and

    reducing a rate at which power is supplied to the thermal sub-cooling device and increasing a rate at which power is supplied to the pump according to the gathered inputs, wherein the reducing and the increasing transition the pumping system from a start-up state to an operational state.
