The function of the softening units include converting calcium and magnesium salt content in the water to sodium salt, making the hardwater usable. These units are utilized in water treatment centers and in industrial applications as part of steam boiler plants and district heating plants, laundries, cooling towers, rinse processes, washing, dishwashing and so on. The versatility of the softening units make them suitable for different industrial applications, both requiring continuous and discontinuous water supply. The flow rate for a standard module is 150 m³/h per unit. Customers can make a choice of one-tank plants, multi-tank plants, cold water or hot water plants. The durability of the tanks in these units are ensured as they are made of steel and coated with polyethylene. The units are accompanied by their controlling units, for example, there are timer controlled units and meter controlled units as well.
