Product Description
AIXBOILER, a leading A-GRADE boiler manufacturer in China with over 45 years of expertise since 1978, offers oil/gas fired thermal oil boilers (also known as thermal fluid heaters or hot oil boilers). These systems heat organic thermal fluids in a closed loop to high temperatures (up to 400°C) at low pressure, providing safe, uniform indirect heating without the risks of steam systems.
Manufactured in our advanced facility in Taikang Industrial Park, Zhoukou City, Henan Province—the “Hometown of Boilers”—AIXBOILER thermal oil boilers feature multi-coil designs for optimal heat transfer, large furnace volumes for complete combustion, and imported burners for efficiency. Fuels include natural gas, LPG, diesel, heavy oil, and dual options.
Ideal for industries requiring precise high-temperature control, such as chemicals, petrochemicals, plastics, textiles, food processing, asphalt, and plywood. AIXBOILER emphasizes sustainability with low-emission burners and high-efficiency designs, exporting to over 80 countries.
