PROBLEM TO BE SOLVED: To provide liquid circulation equipment capable of preventing corrosion of a piping constituting a circulation route by further increasing a deoxidizing reaction time by lengthening a time to mix together circulation water and a deoxidizing agent and improving a deoxidizing effect through improvement of the efficiency of reaction with dissolved oxygen in circulation water. SOLUTION: This liquid circulation system equipment comprises a water supply pump P to supply water in a water supply tank F to a heat-exchanger X, a heat consumption device Y to consume heat energy taken out from the heat-exchanger X, a circulation route V to circulate water from the water supply tank F through the heat-exchanger X and the heat consuming device Y to the water supply tank F again, and a supply water route V to supply water in an amount equivalent to water, brought into a shortage state in the circulation route V, to the water supply tank F. A deoxidizing agent supply device A to supply a deoxidizing agent from a spot in the halfway point of the water supply route V.
