I. Core Technical Advantages: Comprehensive Innovation from Power to Airflow
German Imported IE2 Efficiency Motor: Balancing Energy Saving and Durability
The motor is the "heart" of a large industrial fan. The CorTec Odin Series uses a German imported ABM gear reduction motor, ensuring efficient operation and long service life from the source.
This motor complies with the IE2 international energy efficiency standard, saving 15%-20% energy compared to ordinary motors. Long-term operation can significantly reduce electricity costs for enterprises, aligning with the "green and energy-saving" trend of modern industry. The motor spindle is made of 42CrMo alloy steel, with an output shaft diameter of up to 35mm, paired with a double oil seal design. This effectively prevents lubricating oil leakage, ensuring stable power output even in industrial environments with high dust and humidity.
Notably, the gearbox uses special performance lubricating oil to achieve "lifetime maintenance-free" operation. This greatly reduces later maintenance costs and the risk of downtime, so enterprises don't need to invest extra manpower and resources in equipment upkeep.
Aviation-Grade Aluminum Alloy Fan Blades: A Perfect Balance of Lightweight and High Strength
Fan blades are the key components determining ventilation effectiveness. The blade design of the CorTec Odin Series integrates dual innovations in material science and fluid mechanics, ensuring efficient, stable airflow with wide coverage.
The blades are made of 6063-T5 aviation-grade aluminum alloy, with a tensile strength of 215MPa, yield strength of 160MPa, and elongation of 15%. This combines high strength with lightweight characteristics. This material is not only corrosion-resistant and oxidation-resistant but can also operate stably for a long time in outdoor or humid environments, avoiding safety hazards caused by material aging.
Based on the Blade Element Momentum Theory, CorTec engineers used ANSYS FLUENT fluid simulation technology to optimize the curved shape and installation angle of the fan blades dozens of times. The final determined blade curve makes the airflow more concentrated and the coverage wider. Actual measurement data shows that with the optimized blades, the air volume increases by 5.7% compared to traditional designs under the same power, more efficiently promoting air circulation within the space and quickly reducing the ambient temperature.
Internal "Two-Connected Four-Disconnected" Reinforcing Rib Structure: Achieving Both Safety and Lightweight
The interior of the fan blade adopts a unique "two-connected four-disconnected" reinforcing rib design—consisting of 2 connected reinforcing ribs and 4 non-connected reinforcing ribs. This structure not only reduces the overall weight of the blade, lowering the motor load, but also enhances the blade's fracture resistance through the support of the reinforcing ribs. Even during high-speed rotation or when subjected to external impact, it maintains structural stability, avoiding safety accidents caused by blade deformation or fracture.
II. Safety Protection System: Multiple Redundancy Designs to Build a Solid "Safety Net"
Large industrial ceiling fans are usually installed at heights of 6-15 meters. Once a malfunction occurs, it could pose a serious threat to personnel and equipment below. Starting from the three dimensions of "anti-falling, anti-loosening, and anti-fracture," the CorTec Odin Series has built a multiple safety protection system to ensure "foolproof" equipment operation.
Wire Rope Anti-Falling System: Dual Protection to Eliminate Falling Risks
The equipment is equipped with a high-strength wire rope anti-falling system. The wire rope passes through the central axis of the extension rod and is wound around the extension rod and the upper connector, forming a dual fixing structure. Even in extreme cases (such as connector loosening), the wire rope can effectively bear the weight of the fan body, preventing it from falling.
In addition, the wire rope is made of corrosion-resistant material. Even with long-term use in humid and dusty environments, it is not prone to rust or breakage, ensuring the long-term effectiveness of the safety protection function.
12.9 Grade High-Strength Screws: Resisting Shear and Fatigue for Firmer Connections
The connection parts between the fan blades and the motor, as well as the fan body and the suspension rod, all use 12.9 grade high-strength screws (made of SCM435 alloy steel). Their tensile strength reaches 1220MPa, and hardness is 39-44HRC, far higher than ordinary 8.8 grade screws (tensile strength about 800MPa).
During equipment operation, the instantaneous torque when the motor starts and the centrifugal force when the blades rotate will exert huge shear forces on the connection parts. The high-strength characteristics of 12.9 grade screws can effectively resist these external forces, avoiding the risk of blade detachment caused by screw loosening or fracture. At the same time, the screw surface undergoes special treatment, making it corrosion-resistant and fatigue-resistant. It is not prone to rust during long-term use, ensuring the stability of the connection parts.
Fan Blade Safety Ring and Anti-Detachment Design: The Last "Safety Defense Line"
Each fan blade is equipped with a safety ring. When the fan blade shifts due to an accident (such as loosening of connection screws), the safety ring will cooperate with the hanger structure to prevent the blade from detaching further, buying time for equipment maintenance.
In addition, the connection part between the fan blade and the pin adopts an "E-shaped reinforcing rib" design. When the fan blade is subjected to tightening force, the E-shaped reinforcing rib will bend slightly. This not only ensures a tight connection between the pin and the fan blade but also absorbs part of the stress through deformation, avoiding fractures at the connection part caused by stress concentration, further enhancing the safety of the blade connection.
Chassis Anti-Detachment Locking Mechanism: Four Additional Screws to Prevent Chassis Loosening
Most large industrial ceiling fans only connect the chassis and the motor shaft with a single screw. On this basis, the CorTec Odin Series adds four additional screws to firmly fix the chassis to the motor housing. This "one shaft, four screws" locking mechanism can effectively prevent the chassis from loosening due to vibration during long-term operation, ensuring that the connection between the motor and the fan body remains stable at all times, and avoiding safety accidents caused by chassis detachment.
III. Intelligent Control System: Precise Adjustment and Convenient Operation and Maintenance
The CorTec Odin Series is equipped with a self-developed intelligent variable frequency control system, supporting functions such as stepless speed regulation, fault alarm, and remote monitoring, making equipment operation more convenient and maintenance more efficient.
Stepless Speed Regulation, Adjusting Air Volume on Demand
The control system uses Danfoss frequency converters and Schneider electric components, supporting 0-100% stepless speed regulation. Users can flexibly adjust the fan speed according to space temperature, personnel density, and ventilation needs to achieve "on-demand ventilation." For example, during high-temperature periods in summer, it can be set to high speed to quickly promote air circulation; in spring and autumn, it can be set to low speed to maintain air flow while reducing energy consumption.
Multiple Fault Alarms, Real-Time Grasp of Equipment Status
The system has built-in multiple protection functions, including ground fault, over-temperature, over-current, under-voltage, over-voltage, short circuit, and phase loss. When an abnormality occurs in the equipment, it will automatically shut down and trigger an alarm, while displaying a fault code on the control panel, making it convenient for maintenance personnel to quickly locate the problem and reduce downtime.
Transparent Observation Window and Status Indicator Lights, More Intuitive Maintenance
The front of the control box is equipped with a transparent observation window. Maintenance personnel can directly observe the operating status of internal components without opening the box door. At the same time, a running status indicator light is equipped on the front of the box door, intuitively displaying the equipment status through different colors (e.g., green for running, red for fault), further improving maintenance efficiency.
