Introduction to ZkLysen EC fan

The Zklysen EC fan is an integrated, high-efficiency, energy-saving fan that combines an intelligent frequency converter with integrated position and temperature sensors, an outer rotor permanent magnet synchronous motor, and a backward-facing centrifugal fan blade.

Introduction to the Energy-saving Advantages of Zklysen EC Fans

Energy-saving advantage 1: Direct-drive structure

The fan commonly seen in the market now is the traditional AC fan. Its main working process is that the motor drives the pulley to rotate, which in turn drives the impeller to rotate. However, there is a significant loss of kinetic energy during the transmission process. Moreover, the maintenance and replacement of the pulley in the later stage will also incur corresponding labor and material costs.

                                                     （Traditional AC fan）

Compared to traditional AC fans, the Zklysen EC fan adopts a brand-new direct-drive EC fan, eliminating the bearing transmission structure and allowing the motor to directly drive the impeller. This fundamentally avoids the kinetic energy loss issue encountered during the operation of traditional AC fans, thereby enhancing the overall efficiency of the fan. In terms of driving, it can achieve an energy-saving effect of 5%.

Energy-saving advantage 2: High-efficiency silent impeller

The common types of impellers in the market mainly include flat and curved plate types, both of which are widely used in China. The Zklysen EC fan adopts an efficient airfoil-type impeller, which is specially designed for air handling units (AHU). Compared to the previous two types of impellers, it provides a more uniform airflow distribution, lower pressure drop, and greater air output. At the same time, because the design of the impeller is more in line with fluid dynamics requirements, it produces lower noise, providing a quieter on-site environment and higher overall efficiency. In terms of the impeller, it can achieve an energy-saving effect of 8%-12%.

Energy-saving advantage 3: High-efficiency motor

The Zklysen EC fan utilizes a high-efficiency EC motor, with an energy efficiency rating slightly higher than IE5 (efficiency 92% to 97%). This motor boasts higher efficiency compared to the commonly found IE2/IE3 motors on the market (efficiency 80% to 88%).

The EC motor adopts a design featuring an outer rotor synchronous motor and a permanent magnet core. Compared to traditional motors, EC motors offer faster and more precise speed regulation; they also boast higher quality and longer lifespan, achieving up to 100,000 hours of use. Due to the rotor being positioned externally, the motor provides greater torque, has a larger surface area in contact with the air, and thus superior heat dissipation performance. In terms of the motor itself, it achieves an energy-saving effect of 8%-10%.

Energy-saving advantage 4: Efficient speed control

The common fan control methods on the market all utilize frequency converters for speed regulation and control. However, frequency converters incur frequency conversion losses, resulting in energy losses.

                                                            （Energy Consumption Curve Chart）

The Zklysen EC fan utilizes an electronic commutator to control the motor speed, achieving stepless speed regulation within a load range of 10% to 100% from 0V to 10V, while maintaining an efficiency of over 90%. Under the same load and different control methods for the same fan, compared to traditional variable frequency control, the Zklysen EC fan can save 10% of energy, with higher precision and efficiency. In terms of control, the Zklysen EC fan can achieve a 10% energy-saving effect.

Summary of energy-saving advantages

Compared to traditional fans, the Zklysen EC fan has the following advantages:

1: The fan is more energy-efficient, achieving an energy-saving effect of 20%-40%;

2: The gas flow field of the overall system is more uniform and stable;

3: Installation and use are more convenient, requiring only 2-3 people to complete;

4: The accident rate has been reduced. If some fans fail and stop operating, other fans can be set to increase their speed to compensate for the loss of air volume. The system does not need to be shut down for maintenance, reducing the losses caused by system downtime;

5: It solves the problems of dirty environment (requiring additional filtration sections), high noise, and labor-intensive maintenance in traditional belt pulley fans, saving maintenance costs of 1,800 yuan per unit per year;

6: Longer lifespan, with a service life of up to 100,000 hours;

7: Adopting an outer rotor design, the fan boasts greater torque, higher efficiency, and superior heat dissipation performance;

8: The DC brushless motor eliminates the current loss and subsequent maintenance costs associated with traditional brushes;

9: With a smaller operating current, the accident rate of motor burnout is lower, and the system is more stable and reliable;

10: Utilizing electronic commutator control, it boasts higher precision, faster control speed, and greater efficiency compared to traditional variable frequency speed regulation;
