Get a quoteAs steam is generated, the TDS level of your boiler water starts to increase. At levels above the manufacturer's specified maximum TDS range, scale deposits begin to form on your boiler drum & tubes. The high TDS water begins to foam which, when carried over by steam, leads to corrosion and deposits on heat transfer surfaces.

Get a quoteOther impurities remain in the boiler water after treatment in the form of dissolved solids. Their concentration will increase as the boiler produces steam and consequently the boiler needs to be regularly purged of some of its contents to reduce the concentration. This is called control of total dissolved solids (TDS control).
