Product Features

High Static Pressure

• The centrifugal fan's three-dimensional blades are optimized by using the outlet boundary layer thickness as the optimization target, allowing the impeller to effectivelygenerate high static pressure at high rotational speeds.The impact on the blade leading edge and the separation at the blade trailing edge are both reduced to varying degrees, thereby decreasing internal flow losses within the impeller and improving efficiency. The reduced blade count design helps maintain good flow separation under high flow conditions, further minimizing flow losses.

Low Noise

• The impeller is made of high-strength aluminum magnesium alloy, ensuring minimal axial and radial runout, reducing imbalance, and effectively controlling vibration. The optimized conical-arc-shaped collector effectively enhances intake efficiency by adjusting the expansion and contraction angles. At the same time, the integrated installation ensures the optimal position of the collector's invasion into the impeller front plate, reducing vortex noise.

Energy Efficiency

• Advanced electromagnetic design: Using the electromagnetic simulation software Ansoft Maxwell and the electromagnetic system is designed and developed through a forward design process.The fully insulated motor shaft solution ensures no electromagnetic corrosion.

• High efficiency: We adopt advanced EC technology, enabling the motor to maintain high efficiency under various operating conditions, significantly reducing energy consumption and helping users save on long-term operating costs.

• Fast response: The motor has excellent speed control capabilities, allowing it to quickly adapt to load changes and ensure stable operation in different working environments.

• Precise control: The precise control algorithms enable the motor to maintain consistent performance in constant airflow and constant speed applications, enhancing overall system reliability.

• Strict quality control: We implement rigorous quality control s standards throughout the production process, from raw material selection to final product testing, ensuring that each motor meets high-performance and quality standards.

• Durability design: The motor is designed with hightemperature and corrosion-resistant materials, ensuring stable operation even in harsh environments extending its service life.

• Long-term performance validation: Through multiple rounds of durability testing and practical application verification, the long-term stability of the motor is fully ensured, reducing maintenance frequency.

Flexible and Percise Control

• 0.1V control accuracy: Using Altium Designer for control system development, the vector control method is employed. By decomposing current into excitation and torque components through coordinate transformation, excellent control precision and response speed are achieved. The sensorless full-speed range control solution for fans ensures stable control even in harsh environments. Additionally, it features MODBUS/VSP speed control, allowing precise fan control and feedback via the RS485 protocol, and can be directly integrated with centralized controllers or BMS systems.

• Nine circuit protection: Nine circuit protection measures are in place to prevent potential risks. For AHU duct negative pressure leading to fan reverse rotation, reverse airflow startup is also supported.

Wide Air Volume Range

• Impeller sizes ranging from310 to 630mmare available to fit different installation spaces, and standard mounting brackets can be selected for quick and convenient installation. Can be combined into a fan wall to achieve greater airflow. EC/DC/AC motors can be selected to match different equipment power requirements. Customizable to meet specific application needs, such as C5 corrosion protection, IP56 protection rating, and operation at temperatures as low as -40°C.

Product Applications

AHU Refurbishment

• The energy loss, high maintenance costs, and potential stability issues commonly associated with traditional belt-driven fans in Air Handling Units (AHUs) are significant concerns for many facility managers. Our innovative fan wall retrofit solution addresses these issues effectively, offering a more reliable and energy-efficient alternative. By replacing conventional forward-curved belt-driven fans with modern EC fans configured in a fan wall system, we can achieve remarkable improvements in performance. This upgrade not only enhances energy efficiency by 20% to 50%but also reduces noise levels, simplifies maintenance, and extends the lifespan of the equipment. It’s a cost-effective and sustainable solution for AHU optimization.

Air Conditioning Equipment

• AHU: With a maximum static pressure of 2300 Pa, the fan satisfies the high-resistance demands of AHU applications. A single fan can deliver up to 6 kW of power and a maximum airflow of 23,000 m³/h. Additionally, for industrial applications, a fan wall combination option is available, providing flexible solutions to meet diverse application requirements

• Rectangular Duct Fan: EC fans are ideal for rectangular duct fans, offering high energy efficiency, precise speed control, and low noise operation. Their compact design and long lifespan make them perfect for tight spaces, ensuring reliable performance and reduced energy consumption. 

• FFU: For FFU (Fan Filter Unit) applications, which require high efficiency, low noise, and stable group control in medium to low static pressure environments, two highly efficient fan models have been specifically developed. This two fans are tailored to meet the unique demands of FFU systems, ensuring optimal performance in such scenarios.
