Product Description
AIXBOILER, a leading A-GRADE boiler manufacturer in China with over 45 years of expertise since 1978, offers advanced condensing oil/gas fired boilers. These units capture latent heat from flue gas condensation, achieving thermal efficiencies over 100% (based on lower heating value), significantly reducing fuel consumption and emissions compared to conventional boilers.
Manufactured in our state-of-the-art facility in Taikang Industrial Park, Zhoukou City, Henan Province—the “Hometown of Boilers”—AIXBOILER condensing boilers feature stainless steel or aluminum heat exchangers for corrosion resistance, integrated economizers/condensers, and low-NOx burners. Available in steam or hot water configurations, they support natural gas, LPG, diesel, and dual fuels.
Ideal for energy-intensive industries like food processing, chemicals, textiles, pharmaceuticals, and district heating, these boilers provide substantial cost savings and environmental benefits. AIXBOILER condensing technology supports global sustainability goals, with units exported to over 80 countries.
