The Energy-Saving EC Axial Fan for Cooling Tower delivers exceptional performance in the harsh, moisture-rich environments of industrial cooling systems. Powered by a corrosion-resistant EC motor, this fan achieves 70% energy savings compared to traditional AC cooling tower fans while delivering up to 25,000 CFM airflow—critical for heat rejection in industrial processes . Constructed with 316 stainless steel impellers and fiberglass-reinforced polyester (FRP) housing, it withstands aggressive water treatment chemicals and humid conditions . Certified to AMCA 210 for performance and IP65 for water/dust protection, it ensures reliable operation in power generation, manufacturing, and HVAC cooling towers . The fan operates efficiently across a temperature range of -10°C to 65°C, maintaining performance in extreme weather conditions.
Every wetted component uses marine-grade materials: 316 stainless steel impellers resist pitting corrosion, while FRP housing provides 10-year UV and chemical resistance . Specialized coatings on motor windings prevent insulation breakdown from moisture and airborne contaminants.
The 12-blade axial design with optimized airfoil profile achieves 82% fan efficiency—15% higher than conventional cooling tower fans . This reduces energy consumption while maximizing heat transfer in the tower fill section.
Integrates with cooling tower control systems via 4-20mA and MODBUS protocols, adjusting speed based on return water temperature. This dynamic regulation reduces energy use by 30-50% compared to fixed-speed fans by matching airflow to thermal load .
Provides critical heat rejection for fossil fuel and renewable energy power generation facilities, maintaining turbine efficiency.
Supports manufacturing processes in chemical, petrochemical, and pharmaceutical plants requiring precise temperature control .
Optimizes performance in large-scale building cooling systems, reducing energy costs for hotels, airports, and campuses.
Under normal operating conditions, the 316 stainless steel and FRP components provide 15+ years of corrosion resistance—doubling the lifespan of standard steel fans .
Yes, the materials resist degradation from biocides, scale inhibitors, and pH adjusters commonly used in cooling tower water treatment .
The fan’s reinforced housing and mounting system withstands wind speeds up to 120 km/h, ensuring safety in severe weather events .
