摘要： PURPOSE: To provide an electroplating equipment not causing the drastic change in layout or increase in cost even when applied to an existing electroplating equipment in the technique to enhance the energy efficiency of an electroplating equipment and whereby the temp. of a plating soln. is precisely controlled. CONSTITUTION: A heat exchanger 6 is provided to a plating soln. feed pipeline 4 between an electroplating tank 1 and a circulating tank 3, and an upstream pipline 4a and a downstream pipeline 4b are connected to the high-temp. liq. side. The upstream pipeline 4a and the downstream pipeline 4b are communicated with a bypass pipeline 4c, and a flow control valve 41 is furnished in the middle of the bypass pipeline 4c. The flow control valve 41 is connected to the electrode 11 of the tank 1 through a controller 22. The water feed pipes 10a and 10b between the washing water storage tank 7 for a washing tank 2 and a pure water feeder 9 are connected to the low-temp. liq. side of the heat exchanger 6. The amt. of plating soln. to be heat-exchanged in accordance with a current strength I is controlled by the controller 22.
