Closed Circuit Cooling System with Separate Towers

In this type of cooling systems, cooling water of the power unit and the melting furnace is completely closed circuit, and there are two cooling circuit, where the melting furnace and power unit have its own towers. Distilled water can be used in the power unit circuit, and mains (soft water) water can be used in the melting furnace circuit. In order to prevent the system from freezing during cold seasons, it is necessary to add mono ethylene glycol. In case of electric cut, mains water or reserve tank can be used to cool the melting furnaces. Apart from these, the furnace circuit pumps can be operated with a generator to ensure water circulation when the electricity is cut off.
