Product Description
AIXBOILER leads China as the top-ranked electric boiler manufacturer with over 45 years of expertise since 1978. Our electric hot air boilers (also known as electric hot air generators or furnaces) produce high-temperature clean air directly via electric heating, eliminating combustion for zero direct emissions, no pollution, and precise control—ideal for sensitive environments like food drying, pharmaceuticals, and textiles.
Leveraging our dedicated electric boiler factory since 2020, AIXBOILER supplies advanced units to major clients including CNPC, Sinopec, and CNNC. Manufactured in Taikang Industrial Park, Zhoukou City, Henan Province, these systems reach efficiencies up to 99.5% and power up to 21,600 kW, delivering hot air for processes requiring uniform, contaminant-free heating.
We offer three innovative heating technologies:
- Resistance Heating Type: Open or finned coils for reliable air heating.
- Electrode (Electromagnetic) Type: High-power indirect heating for large-volume air flows.
- Semiconductor Heating Type: PTC elements for safe, self-regulating high-temperature air.
Perfect for industrial drying, curing, preheating, and space heating in eco-restricted zones.
