scales are very damaging to the boiler because they interfere with the heat transfer and can lead to overheating and eventually, boiler rupture
By using this corrosion inhibitor / oxygen control the build up of sediment deposits and damaging corrosion of water boilers is greatly reduced. Our research and experience recomend to working water boilers at a rate of 0.5 to 1.0 percent of the weight of water in the system. This amounts to 4 up to 8 pounds of powder corrosion inhibitor in 100 gallons of water
