INDEMAK
In this system, cooling water of the power unit and the melting furnace is cooled separately by plate heat exchangers and both are closed circuit. Cooled water from the cooling tower is passed through the primary of both heat exchangers. Distilled water is circulated in the power unit, and mains water is circulated in the melting furnace circuit. Since the melting furnace and the power unit cooling water circulates in closed system, there will be no calcification in the system. Emergency water for melting furnaces can be supplied with manual or solenoid valves. The water to be put into the cold water tank in the primary side at the first filling and to be added to compensate for the losses that may occur during operation should be passed through a water softener.
