Our machine can do very little if it does not rely on water chiller. Therefore, the most accurate answer to this question is yes. Note that gold smelting involves the generation of heat that could escalate to extremely high temperatures. If the water chiller is not used, the machine might encounter various complications.
A water chiller is a device that ensures successful heat exchange between the water and the refrigerant in a closed-loop system. As you can see, it is a necessary device that you might need, especially when you intend to engage in heavy-duty applications.
