Motor
Motor imported from Germany, IE2 energy-saving and high-efficiency motor, the central shaft of the motor is made of 42crMo material, the output shaft diameter is 35mm, and have double oil seals, low-pressure cast aluminium. Its special performance lubricating oil in the reduction box, long service life, and lifetime maintenance-free.
Controller
The CorTec control box uses Danfoss frequency converters and Schneider brand electrical appliances, with radio interference suppression and braking functions. In addition, it is equipped with multiple alarm protection functions such as ground fault, over-temperature, over-current, under-voltage, over-voltage, short circuit, and phase loss; There is a transparent observation window outside the box body, which can observe the operating status in real time. The front of the box is equipped with an operating indicator light, an infinite speed adjustment knob and a three-speed switch.
Fan Blades
MATERIAL
The blades of CorTec are made of 6063-T5 aluminum alloy
6063-T5 aluminum alloy has a tensile strength of 215 MPa, yield strength of 160 MPa, and an elongation of 15%. It also has a Brinell hardness of 60 HB and a shear strength of 150 MPa. This alloy has good formability, high corrosion resistance, and excellent weldability, making it suitable for a wide range of applications in various industries
High strength: 6063-T5 aluminum alloy has a high tensile and yield strength, making it suitable for structural applications
Good corrosion resistance: This alloy has excellent resistance to corrosion, which makes it suitable for outdoor and marine applications
OUTLINE
Based on the Blade Element Momentum Theory, CorTec has gone through repeated designs to identify the optimal curve and angle of the fan blade. If you wish to preview the actual appearance, please directly contact us (the actual dimensions are confidential and have been patented)
CorTec compared dozens of different aerodynamic designs using ANSYS FLUENT simulations and identified the shape that yielded the maximum airflow under equivalent power conditions. As illustrated in the following images, which depict two distinct fan blade profiles, the wind speed heatmaps generated by their rotations are vastly different. Specifically, the airflow volume on the left is 5.7% greater than that on the right
Structure
The internal structure of the CorTec fan blade has a special design:
It contains two connected reinforcement ribs and four unconnected reinforcement ribs, which makes the fan blade lightweight and more resistant to fracture
When the fan blade is connected to the plug-in and the nut and nut tighten the fan blade and the plug-in, the two "E-shaped" reinforcement ribs have a certain deformation ability. When the fan blade is subjected to the tightening force from top to bottom, the reinforcement ribs will bend slightly, which can not only ensure the close connection between the plug-in and the fan blade, but also ensure the structural strength of the fan blade.
Beam connecting part
CorTec special design, with 8mm thickness plate, and special bend, robot welding technology, can totally ensure fans safety to avoid any accident happened.
CorTec can provide wind flow simulation (CFD) for VIP clients or Large Projects, which requires you to provide 3D drawings of the project. Our engineers will select the appropriate size of fans and calculate the number of fans needed for the project to achieve the most suitable ventilation effect while being more economical.
