Boiler Blowdown Tanks | Niles Steel Tank

Boiler Blowdown Tanks are an essential part of a steam heating system. As water turns to steam in these systems, small amounts of solids are collected in the boiler as evaporation of steam dissolve impurities from the water and piping. Left untreated, these impurities can reach significant levels and potentially cause damage to the steam boiler.
