Water type mold heaters have been widely used by most manufacturers due to their excellent maintenance of the production environment and thermal conductivity. However, due to the chemical properties of water at 60 to 80 ℃, they are prone to cracking, and during the heating process, oxygen in the water is released, resulting in the oxidation of minerals in the water and the production of substances such as magnesium oxide and calcium oxide. These substances are commonly referred to as scale, which can seriously affect the life of the mold heater. Therefore, the method to remove minerals in the water is to soften, "We can use the water filtered by the filter as a supplement to the circulating water. Due to the lack of minerals, the formation of scale is greatly reduced.".
With a good water source, it is very important in the entire cooling system. Generally, we use cooling towers for cooling water. Because they use air to cool them, the cost is low, but it also increases the oxygen content of the water. It is easy to mix particles and dust in the air oxygen into the cooling water, resulting in water color confusion, which can lead to pipe blockage and damage to parts of the pipeline that are prone to scratches (such as gaskets, shaft seals, etc.). Using closed loops is currently the most effective method
