Do I Need a Deaerator?
Deaerators mechanically eliminate dissolved gases from boiler feedwater through heating, agitation, and gas liberation. By significantly reducing the levels of dissolved oxygen, carbon dioxide, and other non-condensable gases, deaeration plays a crucial role in protecting industrial steam systems from the damaging effects of corrosion. This reduction helps to minimize the risk of corrosion-related issues, thereby enhancing the overall efficiency and longevity of the system. Deaerator tanks are not required for all installations. Contact us to determine if a deaerator is suitable for your installation.
Why Use a Deaerator?
Deaeration minimizes oxygen and carbon dioxide corrosion within boilers and their associated piping systems. By implementing preheated feedwater, the risk of thermal shock—resulting from the expansion and contraction of heating surfaces—can be significantly reduced. Mechanical deaeration offers a reliable solution for oxygen removal, eliminating the need for costly chemical alternatives. Moreover, continuous deaeration effectively lowers the overall CO2 levels in the steam system, which can lead to decreased maintenance costs over time.

What Are the Advantages of Using a Deaerator?
- Deaerators remove dissolved gases from the boiler feedwater, particularly oxygen and carbon dioxide. This helps prevent piping, boilers, and other equipment corrosion and extends their lifespans.
- Deaerators contribute to more efficient boiler operation by ensuring that steam is created from high-quality, oxygen-free water. This improves steam output and reduces fuel consumption.
- Deaerators significantly reduce the need for maintenance and repairs by minimizing corrosion and scale build-up. They also help maintain system integrity and can lower maintenance expenses over time.
- A deaerator helps maintain steam quality and reduces risks associated with corrosion-related failures, which can pose safety hazards in industrial environments.
- By increasing the thermal efficiency of the steam system and reducing fuel waste, deaerators can lead to significant energy savings, which translates to lower operational costs
- With a deaerator, the feedwater quality remains consistent, which is crucial for efficiently operating boilers and heating systems.
- Removing dissolved gases improves the boiler and steam system's overall reliability, resulting in more stable and efficient operation.

What is a deaerator?
Deaerators are mechanical devices that remove dissolved gases from boiler feedwater through a heating, agitation, and liberation process. Deaeration protects industrial steam systems from the effects of corrosive gases by reducing the concentration of dissolved oxygen, carbon dioxide, and other noncondensable gases to a level where corrosion is minimized.
What is the purpose of a deaerator in a boiler system?
A deaerator’s primary purpose is to remove dissolved gases, particularly oxygen and carbon dioxide, from the feedwater before it enters the boiler. By eliminating these gases, a deaerator helps prevent corrosion in the boiler and associated equipment, which can extend the lifespan of your system and enhance overall efficiency.
How does a deaerator work?
Deaerators use heat and pressure to remove gases dissolved in water. Feedwater is heated to near-boiling temperatures within the deaerator, allowing gases to escape. This process typically involves a combination of flashing steam and a tray or spray design that maximizes contact between steam and water to ensure efficient gas removal.
Why is deoxygenation important?
Oxygen is highly corrosive, especially in high-pressure boiler environments, and it can cause pitting and other forms of metal degradation.
