De-aerators play a vital role in industries like power generation, food processing, and chemical manufacturing by removing dissolved gases, such as oxygen and carbon dioxide, from liquids. This is essential to prevent corrosion, maintain equipment efficiency, and enhance product quality. De-aerators work by heating the liquid and utilizing steam to strip out unwanted gases, ensuring the liquid is free from harmful air content. Renowned manufacturers like SPX FLOW, Stork, and Thrush Co. produce highly efficient de-aerators known for their reliability in demanding environments.
These systems come in various designs, such as spray-type and tray-type models, tailored to different industrial applications. Whether conditioning boiler feedwater or preparing liquid ingredients, selecting the right de-aerator is critical for ensuring process integrity and extending the life of your equipment.

What is the primary function of a de-aerator in industrial processes?
A de-aerator’s primary function is to remove dissolved gases, particularly oxygen and carbon dioxide, from water or other fluids. This is crucial in preventing corrosion and scaling in boilers, pipes, and other equipment, which can lead to increased maintenance costs and reduced operational efficiency.
What types of de-aerators are available, and how do they differ?
Common types of de-aerators include tray type, spray type, and vacuum type. Tray-type de-aerators use trays to promote gas-liquid contact, spray-type de-aerators use spray nozzles to disperse the liquid, and vacuum-type de-aerators utilize a vacuum to remove gases. Each type varies in design and efficiency based on the specific requirements of the application.
How do I choose the right de-aerator for my system?
Selecting the right de-aerator depends on factors such as the volume and temperature of the fluid, the level of gas removal required, and the specific application. Consider the flow rate, operating pressure, and compatibility with your existing system. Consulting with a de-aerator manufacturer or supplier can help you determine the best option for your needs.
What maintenance is required for de-aerators to ensure optimal performance?
Regular maintenance for de-aerators includes inspecting and cleaning the internal components, checking for any leaks, and monitoring the performance to ensure efficient gas removal. It’s important to regularly check the condition of the de-aerator’s seals, valves, and drain systems. Following the manufacturer’s maintenance guidelines will help ensure reliable operation and prolong the lifespan of the equipment.
What are the common issues that can affect a de-aerator’s performance, and how can they be addressed?
Common issues with de-aerators include gas pockets, inadequate removal of gases, and scaling or fouling of internal components. These issues can be addressed by regularly inspecting and cleaning the equipment, adjusting operational parameters, and ensuring that the de-aerator is correctly sized for the application. Addressing any issues promptly and performing routine maintenance can help maintain optimal performance.
