Water softeners remove calcium and magnesium (hardness) and replace them with sodium. Hardness removal is critical to prevent scale formation on the waterside of the boiler. Scale can decrease boiler efficiency by 10% and create premature pressure vessel failure. Fulton softeners are duplex systems with auto-regenerating features sized for each application.

The quality of the water used in a steam boiler will affect its life. It is strongly recommended that a competent water treatment program, which includes a chemical feed system, is implemented. High-quality feedwater will minimize the formation of scale, foaming, solids in steam, corrosion, and fouling caused by the solids and gases present in natural feedwater.

Carbon filers contain a filter media of activated carbon – coal based.
