The global Atmospheric Deaerator market size is predicted to grow from US$ 3032 million in 2025 to US$ 8514 million in 2031; it is expected to grow at a CAGR of 18.8% from 2025 to 2031.

Atmospheric deaerator is designed to remove corrosive gases (oxygen and free carbon dioxide) from water, to feed steam boilers and make-up water of the heating system.An atmospheric deaerator unit having a vessel divided into an atmospheric section and a low pressure section, the low pressure section containing steam supply line for deaerating a water spray circulated from the atmospheric section through a water circulating line using a series of spray heads for spraying water into the low pressure section, the circulating line communicating between the low pressure section and the atmospheric section, the atmospheric section having a vent open to atmosphere with a vent condenser to purge vented non-condensible gases from the atmospheric section, and, the low pressure section being pressure protected by a water column conduit communicating between the vessel sections to return overflow water and blow-through excess pressurized steam and vapor from the pressurized section to the atmospheric section, the unit being controlled by a steam control valve using pressure of the pressurized section or water temperature in the atmospheric section.

The market drivers for atmospheric deaerator are mainly related to the need for reducing corrosion and improving efficiency in steam-generating boilers. Some of the factors that may boost the demand for atmospheric deaerator are:

Increasing water scarcity and depleting groundwater levels in some regions, which require alternative sources of water for boilers.

Growing awareness of environmental issues and regulations, which encourage the use of energy-efficient and eco-friendly technologies for water treatment.

Rising demand for power generation and industrial applications, which require reliable and high-quality boiler feedwater.

The constraints of atmospheric deaerator are mainly related to the high capital and maintenance costs, as well as the technical challenges of operating at low pressure and temperature. Some of the factors that may hinder the growth of atmospheric deaerator are:

High initial investment and installation costs, which may deter some potential customers, especially in developing countries.

High energy consumption and operational costs, which may reduce the profitability and competitiveness of atmospheric deaerator compared to other water treatment methods.

Low efficiency and performance at low relative humidity and temperature conditions, which may limit the applicability and suitability of atmospheric deaerator in some regions.

The future opportunities for atmospheric deaerator are mainly related to the innovation and development of new technologies and products that can overcome the existing limitations and challenges. Some of the possible opportunities for atmospheric deaerator are:

Incorporating smart technologies and Internet of Things (IoT) devices that can enhance the user-friendliness and functionality of atmospheric deaerator.

Developing hybrid systems that can combine atmospheric deaerator with other water treatment methods, such as reverse osmosis or membrane distillation, to improve the quality and quantity of water production.

Expanding the market penetration and customer base of atmospheric deaerator in emerging regions, such as Asia Pacific and Middle East & Africa, where there is a high demand for water security and sustainability.
