Disclosed is an industrial water treatment device comprising a heat exchanger (1) whose primary circuit (20) is connected to a hot water flow pipe (6) and a hot water return pipe (8). A mixing valve (4) which is controlled by a temperature sensor (5) is disposed in the hot water flow pipe (6). A connection of said mixing valve is joined to a source of water whose temperature lies below the temperature of the hot water flow pipe (6). An industrial water supply pipe (9) and an industrial water discharge pipe (10) are connected to the secondary circuit (21) of the heat exchanger (1). In order to prevent the heat exchanger (1) from calcifying even at elevated hot water temperatures while obtaining quick regulation and ensuring a low hot water return temperature, the primary circuit (20) is provided with at least one intermediate connection (1.2) that is joined to the mixing valve (4). |
