Air Separator (Deaerator)
Advanced deaeration solutions for steam generation systems and boiler feedwater treatment



About Air Separators (Deaerators)
Air Separators, commonly known as Deaerators, are critical components in steam generation systems, designed to remove dissolved oxygen and carbon dioxide from boiler feedwater. By reducing oxygen levels to as low as 7 ppb, deaerators help prevent corrosion, protect boiler systems, and improve overall plant efficiency and reliability.
At Avant Tech, we partner with Flometriq, a globally recognized manufacturer of high-performance thermal Deaerators, to provide reliable air separation solutions for industrial and power generation applications. Manufactured in India to international standards including ASME, HEI, BS, and DIN, these systems are engineered for dependable performance in demanding environments.
Available in both tray-type and spray-type configurations, Flometriq Deaerators are widely used in power plants, refineries, co-generation facilities, oil & gas installations, paper mills, steel plants, hospitals, and pharmaceutical industries. Constructed from Carbon Steel, Stainless Steel, and specialty alloys, they undergo rigorous quality testing to ensure long-term reliability and operational safety.
Through our partnership with Flometriq, Avant Tech delivers proven deaeration solutions backed by decades of engineering expertise, helping customers enhance boiler protection, reduce maintenance costs, and achieve greater operational efficiency.
