During formation in the boiler steam leaves behind impurities, total dissolved solids (TDS). If left these impurities concentrate and could cause damage to your boiler.
In addition these solids build scale on the fire tubes and reduce the heat transfer. The effect is higher steam production costs.
Total dissolved solids controls measure the electrical conductivity of the boiler water which detects the level of total dissolved solids in your boiler.
Accurate control of total dissolved solids minimises blowdown, reduces the risk of boiler carryover, improves productivity and significantly reduces operating costs including fuel and chemical treatment.
