Ningbo Dingtong Metal Products Co., Ltd

 

The company was established in 2019 and is one of the earliest enterprises in China to research and develop large industrial fans. At present, the products are widely used in factory workshops, warehouses, basketball courts, outdoor restaurants and other high-ceiling spaces both at home and abroad, achieving the effect of ventilation and cooling. The fan adopts advanced technology, with the maximum diameter reaching 7.3 meters. The fan has focused on comprehensive disciplines such as aerodynamics, transmission dynamics, etc., and can efficiently circulate air to improve the comfort of the environment. It is made of high-strength materials such as aviation-grade magnesium alloy to ensure safety and durability. The fan hub is made of Q460 high-strength steel, one-piece molding, with higher safety. In addition, the tube-type connector and aerodynamic fan blades also extend the service life, improve stability and energy efficiency. The control system can be equipped with Schneider Electric components, German brand controllers, or Chinese domestic KEWO brand, emphasizing safety and protective functions, and the overall performance and efficiency of the fan are industry-leading.

â–¼ Permanent magnet synchronous motor

Adopting permanent magnet synchronous motor, ultra-low temperature rise, ultra high torque, industry-leading 3D convection heat dissipation technology. The external rotor design eliminates the frictional energy consumption of the gearbox compared to traditional asynchronous motors, and the motor as a whole does not require maintenance, making it convenient and more durable. The greater advantage is that it can output more stable air volume, achieving a full load air volume of 800000 cubic meters per hour, which has been highly praised by the market since its launch.

▼ Control System：

Kowo brand, frequency conversion saves 1 kWh of electricity per hour. Built in safety protection module, with up to 33 protections including over temperature, over-current, overload, over-voltage, and ground protection, with a protection level of IP55.

▼ Fan Blade：

Known as aviation aluminum, the fan blade material T6063-T5 is lightweight, high-strength, and corrosion-resistant; The width of a single fan blade is 183mm, the length is 3.45m, and the weight of a single fan blade is about 8 kilograms. The air volume is larger and the range is wider.
