A washing machine manufacturer in the United States had accumulated a large amount of scale on their boilers, which was affecting their fuel consumption, overall costs, and steam efficiency, resulting in frequent boiler shutdowns.

The previous water treatment provider was treating the manufacturer’s boilers with a phosphate-based program, but without a water softener system in front of the boilers to remove hardness, the phosphate program led to calcium phosphate scale.

Kurita performed an initial site inspection of the manufacturer and found large quantities of scale in the boiler. If boilers are not treated correctly, excessive scale crystallization will deposit on the heat transfer surfaces.
