Two of the most important and widely produced industrial chemicals are sulfuric acid and phosphoric acid. Both acids are essential to the agriculture industry as fertilizer and are used in the manufacturing of detergents and batteries. Sulfuric acid has a vast range of specific uses in most industries such as petroleum and explosives, while phosphoric acid is added to soft drinks.
An exothermic reaction occurs when water and sulphur trioxide are absorbed into sulphuric acid and the result is an increase in the temperature of the acid. The temperature of the acid must be cooled. The acid cooling removes the heat from the acid flow and protects the equipment and the process from overheating.
A typical acidic application that requires a chiller system is acid copper plating. The chiller maintains the process at a specific temperature so that the acid process is protected. The acid cooling chiller is used to control the temperature between 25° – 28°C, and the temperature difference of in/out refrigerating liquid within a couple degrees
