The application of Kemao fans in evaporative cooling systems (evaporative cooling) and cooling towers is mainly aimed at high-energy consumption scenarios such as industrial refrigeration, data center heat dissipation, and chemical circulating water cooling. Through efficient ventilation and intelligent control technology, the system energy efficiency and stability are improved. The specific applications are as follows:
I. Core application scenarios and technical advantages
Evaporative cooling system
Efficient cooling: Kemao fans use large-flow axial flow fans (air volume can reach 10,000~50,000 m³/h) to drive air and water film forced heat exchange, improve evaporation efficiency, and reduce the outlet temperature by 8~12℃ in high-temperature and dry areas (such as the northwest).
Corrosion-resistant design: The fan blades and shells are made of polymer anti-corrosion coatings (such as PP/FRP materials), which can withstand high humidity, acid, alkali and salt spray environments, and the service life is extended by more than 50% compared with ordinary carbon steel fans.
Intelligent frequency conversion control: Automatically adjust the fan speed according to the ambient temperature and humidity, dynamically match the load demand, and reduce the comprehensive energy consumption by 20%~30%.
Cooling tower system
Enhanced heat dissipation: low-noise centrifugal fans are used to optimize the airflow distribution in the tower and improve the heat exchange efficiency of the cooling tower. The circulating water can still be cooled to below 32°C under high temperature conditions of 40°C, meeting the needs of chemical, power and other industries.
Anti-drifting technology: through the design of honeycomb water collector + guide vane, the water droplet drift loss is reduced, the drift rate is ≤0.001%, and the water saving effect is significant.
Energy-saving transformation: replace the traditional cooling tower fan with Kemao permanent magnet synchronous motor (IE5 level), and the annual power saving of a single unit can reach 50,000~80,000 kWh.
2. Typical industry application cases
Data center evaporative cooling
Case: A data center in Ningxia uses Kemao fan + indirect evaporative cooling system, the natural cooling time throughout the year is extended to 80%, the PUE value is reduced from 1.5 to 1.2, and the annual electricity bill is saved by more than 3 million yuan.
Technical highlights: The fan is linked to the BA system, which is dynamically started and stopped according to the server load to reduce ineffective energy consumption.
Circulating water cooling in steel plants
Case: A cooling tower renovation project in a steel plant in Hebei Province used Kemao anti-corrosion fans to replace traditional equipment. It has been running continuously for 3 years without any failure in a high temperature and high dust environment, and the maintenance cost has been reduced by 40%.
Technical highlights: A self-cleaning nano-coating is added to the surface of the blades to reduce the efficiency attenuation caused by dust adhesion.
Chemical plant process cooling
Case: The evaporative cooling system of a chemical plant in Zhejiang Province is equipped with Kemao variable frequency fans. Through precise temperature control, the cooling efficiency of the reactor is increased by 25%, avoiding defective products caused by temperature fluctuations.
Technical highlights: Support MODBUS protocol, seamlessly connect with the PLC system, and realize fully automatic control.
III. Technological innovation and market competitiveness
Patented technology support
Anti-scaling fan structure (patent number CN 218XXXXXX): Through the spiral guide groove design, scale deposition is reduced and the maintenance cycle is extended to more than 2 years.
Intelligent monitoring system: Built-in vibration and temperature sensors, real-time warning of faults, and operation and maintenance response efficiency increased by 60%.
Industry certification and cooperation
Passed CTI (American Cooling Tower Association) performance certification, suitable for cooling tower renovation of international brands such as Marley and Spindler.
Cooperated with Huawei, GDS and other companies to provide customized evaporative cooling fan solutions, and the domestic industrial cooling market share reached 22% in 2024.
Environmental benefits
A single cooling tower fan can reduce CO₂ emissions by 50~80 tons per year, helping enterprises achieve the "dual carbon" goal.
