Abstract
A combined, temperature-controlled chemical recirculation and replenishment system including a first conduit defining a recirculation loop conducted between the drain and the inlet of a reactant tank. A pump recirculates reactant chemical through the first conduit, and a controllable heater is connected to the first conduit for heating the reactant chemical. The heat sensor is connected to the heater for sensing the temperature and outputting the temperature signal to a controller. A second conduit is connected between a replenishment tank and the pump. A controllable valve is connected in the second conduit. A controller is connected both to the heater and to the controllable valve. The controller receives the temperature signal from the sensor and is responsive to that temperature signal to activate the heater to maintain the reactant at the optimum temperature. The controller is also responsive to the temperature signal for opening the controllable valve when the reactant is at the optimum temperature, thereby allowing replenishment reactant to flow through the second conduit and to enter the recirculation loop via the pump.
