Product Application
In the industrial sector, it is widely applied in energy-saving retrofits of fans and water pumps, replacing valve control with speed regulation, achieving energy savings of 30%-50%. Additionally, it provides soft start, stepless speed regulation, and torque control for machine tools, conveyor belts, cranes, and injection molding machines, enhancing the level of automation.
In the fields of energy and infrastructure, frequency converters are the core of heating, ventilation, and air conditioning (HVAC) systems, dynamically regulating chilled water pumps and fans. They are also used in auxiliary equipment of power plants, water treatment, and new energy fields (such as wind turbine pitch control and photovoltaic water pumps).
In addition, it has key applications in transportation (electric vehicles, rail transit), environmental protection (wastewater treatment blowers), special equipment (tension control of textile machinery), and even household appliances (variable frequency air conditioners, refrigerators).
