ACI Universal Blower Dedicated Variable Frequency Converter
The universal fan frequency converter is a variable frequency speed control device specially designed by ACI for fan loads. It can achieve smooth adjustment of fan speed by adjusting the motor power supply frequency and voltage, thereby meeting the air volume requirements under different working conditions, while achieving energy saving, noise reduction, and extending equipment life.
Main features
- Efficient and energy-saving
According to the load characteristics of the fan (square torque load), the frequency converter can significantly reduce shaft power consumption by reducing the speed, and the energy-saving rate can usually reach 20%~60%.
Suitable for loads such as fans and pumps where flow rate is proportional to speed, avoiding energy loss caused by traditional baffle adjustment.
- Soft start and soft parking
Reduce the impact current during motor start-up and minimize damage to the power grid and mechanical equipment.
The soft parking function can prevent water hammer effect and protect the pipeline system.
- Wide range speed regulation
The output frequency range is wide (such as 0-500Hz), which can meet different speed requirements.
High speed regulation accuracy, fast response speed, and adaptability to complex working conditions.
- Multiple control modes
Support V/F control, vector control (sensorless vector control/sensorless vector control), etc.
It can achieve closed-loop control functions such as constant pressure air supply and constant flow control.
- Complete protection function
Built in overload, overvoltage, undervoltage, overcurrent, overheating and other protection functions ensure the safe operation of the equipment.
Fault self diagnosis and alarm function, easy to maintain.
- Strong adaptability
Suitable for various types of fans (such as centrifugal fans, axial fans, etc.).
It can be linked with PLC, DCS and other systems to achieve automation control.
Application
- Industrial ventilation and dust removal
The ventilation and dust removal system in the factory workshop adjusts the air volume according to production needs.
- Heating, Ventilation, and Air Conditioning (HVAC)
Central air conditioning systems, boiler induced draft fans, cooling tower fans, etc., achieve energy-saving and comfort control.
- Environmental protection engineering
Aeration fans for sewage treatment plants, induced draft fans for waste incineration plants, etc.
- Electricity and Energy
Boiler fans and induced draft fans in power plants achieve efficient and energy-saving operation.
- Architecture and Agriculture
Building ventilation systems, agricultural greenhouse ventilation, etc.
