Air Separator (Deaerator)

About Air Separators (Deaerators)

Air separators, also known as deaerators, are essential equipment in steam generation systems designed to remove dissolved gases (primarily oxygen and carbon dioxide) from boiler feedwater. Dissolved oxygen in feedwater causes serious corrosion damage to boiler walls, metal piping, and other internal components by forming oxides (rust). Carbon dioxide combines with water to form carbonic acid, leading to further corrosion. Our deaerators reduce oxygen content to as low as 7 parts per billion (ppb), ensuring maximum boiler protection and efficiency.

We offer both tray-type and spray-type thermal deaerators engineered for superior performance in power plants, refineries, industrial facilities, and marine applications. Manufactured in India to international standards (ASME, HEI, BS, DIN), our air separators feature robust construction with options in carbon steel, stainless steel, and specialty alloys. Each unit undergoes rigorous testing including post-weld heat treatment, X-ray inspection, and ultrasonic verification to guarantee reliability under demanding conditions.

With decades of deaerator design and manufacturing expertise, we provide solutions for co-generation plants, hospitals, oil fields, paper mills, steel mills, and pharmaceutical facilities. Our deaerators combine thermal efficiency with minimal pressure drop, comprehensive material options for corrosive environments, and compliance with major international standards including ASME Boiler & Pressure Vessel Code and NACE International recommendations.
