Deaerators are critical components for treating boiler makeup water. If not removed, dissolved gases like oxygen, carbon dioxide, and ammonia will cause corrosion in the boiler system. Filtrex Solutions has expertise servicing every kind of deaerator system, including tray-type and spray-type, both of which rely on steam scrubbing the water to remove dissolved gases. We will tailor our treatment approach to ensure your assets are protected and downtime for cleanings is reduced. Filtrex Solutions field engineers begin their treatment approach with a thorough examination of our customer’s deaerators. They inspect the installation, level, internal parts, funnels, and pipes to ensure that scale or debris has not accumulated, preventing flow within the system.
In our experience, some of the operational issues that can severely impact performance include:

• Operation outside rated capacity
• Improper or damaged pressure-reducing valves
• Failure to maintain continuous positive steam pressure
• Infrequent or improper venting
• Leaks in the external vent condenser
• Contaminating deaerated water with oxygenated water
