Boiler Chemicals
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.
Oxygen Scavengers
Oxygen scavengers are added to boiler water to remove oxygen and prevent corrosion. Oxygen is enemy #1 in boiler water.
Osorno’s Oxygen Scavenger is packaged in 4 litre jugs and returnable 20 litre delcans. One delcan is sufficient to treat 5,000 L of boiler water, and can capture the oxygen content of 1,400 L of air. Oxygen scavengers adjust the pH of boiler water to between 8.5 and 9.0.
For boiler systems with aluminium components, oxygen scavenger is available with increased aluminium protection.
In Osorno Store can be purchased:
Osorno Oxygen Scavenger in 4 l jugs and 20 l delcans.
Osorno Oxygen Scavenger with Aluminum Protection in 4 l jugs and 20 l delcans.
Boiler Anti-Scalants
Boiler anti-scalants are widely used to reduce scale formation. Scale build up can lead to explosive local overheating, and even rupture of the boiler. Prior to offering Osorno Boiler Antiscalant, Osorno personnel will measure the amount of antiscalants required for boiler systems free of charge for clients.
In Osorno Store can be purchased Osorno Boiler Antiscalant 4 l jugs and 20 l delcans.
