Tray and Spray Deaerator Market Size 2025–2032 is projected to grow from USD 1.93 billion in 2025 to USD 2.67 billion by 2032, registering a CAGR of 4.30%, driven by rising demand for boiler feedwater oxygen removal systems, power generation expansion, and industrial steam optimization.

Market Estimation & Definition

Tray and spray deaerators are essential components in boiler feedwater systems, designed to remove dissolved gases such as oxygen and carbon dioxide. These gases, if not eliminated, can lead to corrosion, reduced efficiency, and increased maintenance costs in boilers and steam systems. Deaerators help improve operational reliability, extend equipment lifespan, and optimize thermal efficiency.

The market was valued at USD 1.93 billion in 2025 and is projected to reach USD 2.67 billion by 2032. In volume terms, the market stood at approximately 218,105 units in 2025, reflecting strong demand across utilities and industrial sectors. The market includes both tray-type and spray-type deaerators, each serving distinct operational requirements based on scale, efficiency, and system design.

Tray-type deaerators are typically used in large-scale power plants due to their superior oxygen removal efficiency, while spray-type deaerators are widely adopted in compact and mid-sized industrial applications due to their flexibility and cost-effectiveness.
