Steam Boiler Water pH Control - Controls 4 Steam

The safe pH range for steam boilers is between 8.5pH & 12.7pH, whilst the recommended level is between 10.5pH & 12.0pH. Boiler water with a pH of 10.5 contributes 12.6mg/l towards the boiler TDS, whilst at a pH of 12.0 it increases to 400mg/l and at 12.5pH the value is 1264.9 mg/l a 100 fold increase.
