Boiler water treatment products incorporate oxygen scavengers, and alkalinity boosters for corrosion inhibition, and anti-scalants to prevent concrete-style scale build-up in boilers. Addition of boiler chemicals minimizes or even eliminates corrosion and scaling inside a boiler and significantly prolongs its lifetime. This is the simplest and most cost-effective way to protect your investment in a boiler system.
Simple tests can determine whether boiler water treatment is required with speciality chemicals:
- Test pH: Ideally, the boiler water should be moderately alkaline (pH 9.0 – 9.5 for steel boilers, 8.5 – 9.0 for systems with aluminium heaters). An inexpensive pH tester can be purchased from Avalon Science Store.
- Test ORP: The oxidation-reduction potential (ORP) should be negative (-100 mV or lower), indicating a reducing environment. An inexpensive ORP tester can be purchased from Avalon Science Store.
- Measure Calcium Concentration. Osorno will measure the calcium concentration to determine the need for anti-scalants, free of charge for clients.
pH and ORP should be tested weekly, and the calcium concentration should be measured every quarter, as well as when make-up feedwater is added.
