Basic Performance Parameters
Energy Efficiency Grade
Meets Class 2 energy efficiency standards in GB/T 7190.1-2018, with power consumption ratio ≤0.030kW/(m³/h) (combined energy consumption of fan + water pump).
Compared with ordinary cooling towers (power consumption ratio >0.035kW/(m³/h)), energy saving rate ≥14%.
Drift Rate and Makeup Water
Water-saving open tower drift rate ≤0.001%, closed tower as low as 0.005%.
Makeup water: For closed towers, it is 0.1–0.2‰ of the circulating water volume, saving water by more than 50%.
Structural Design Parameters

Technical Indicators |
Fan Configuration |
High-efficiency axial flow fan (efficiency >75%), motor energy efficiency meets GB18613-2020 Class 2 standard |
Heat Exchanger |
Copper tube aluminum fin design (closed tower heat exchange efficiency increased by 3 times, reducing spray dependence) |
Tower Body Material |
Fiberglass (HBLG3 series), galvanized steel or carbon steel hot-dip galvanizing (corrosion protection) |
Operating Modes and Water-Saving Strategies
Multi-Mode Switching
Adiabatic Mode: Air is pre-cooled by wet curtain, with summer spray assistance, reducing operating energy consumption by 40%.
Dry Air Mode: In the transition season, only rely on natural air cooling, and close the spray system.
Intelligent Control
Real-time monitoring of ambient temperature and humidity, automatically matching cooling mode (e.g., using high-efficiency spray when wet-bulb temperature ≥28℃).
