As the melting system has relatively larger power, generally above 200KW, a large cooling system is required to reduce the high temperature it generates during operation. The commonly used water cooling systems include open water cooling towers and closed water cooling towers.
- The open water cooling tower is cheaper but large in volume.
- The closed water cooling tower is more expensive than the open cooling tower but has better cooling effects. It is easy to maintain and has smaller volume, suitable for indoor use.
