Product Description
AIXBOILER, a leading A-GRADE boiler manufacturer in China with over 45 years of expertise since 1978, offers biomass/coal fired thermal oil boilers (thermal fluid heaters). These systems heat organic thermal oils in closed loops to high temperatures (up to 400°C) at low pressure using solid fuel combustion, providing safe, uniform indirect heating.
Manufactured in our advanced facility in Taikang Industrial Park, Zhoukou City, Henan Province—the “Hometown of Boilers”—AIXBOILER boilers feature helical coil designs for optimal heat transfer, chain or reciprocating grates for reliable fuel burning, and large furnaces for complete combustion. Fuels include various coals, biomass pellets, wood chips, rice husk, straw, and agricultural wastes—enabling renewable, cost-effective operations.
Ideal for high-temperature processes in chemicals, petrochemicals, plastics, textiles, food frying, asphalt, and plywood industries. AIXBOILER focuses on sustainability with efficient combustion and emission controls, exporting eco-friendly solutions to over 80 countries.
