The energy efficiency rating of an electric flapgate is not directly for the rating of the flapgate itself, but for the energy efficiency rating of its internal electric motor. In China, the energy efficiency rating of electric motors follows GB 18613-2020 standard, which specifies the energy efficiency rating and energy efficiency limit values of three-phase asynchronous motors, single-phase asynchronous motors and motors for air conditioner fans.
According to GB 18613-2020, the energy efficiency rating of electric motors is divided into three levels:
Energy efficiency limits(Efficiency Limit Value): This is the minimum energy Efficiency requirement, and the electric motor must at least meet this level.
Level 3 Energy Efficiency(IE3): This is the basic energy Efficiency rating, also known as "Premium Efficiency".
Level 2 Energy Efficiency(IE2): This is a lower energy efficiency rating, but it is still allowed under certain circumstances.
The electric motors used by electric flapper doors typically follow these energy efficiency ratings. When choosing an electric baffle door, you can ask the specific energy efficiency rating of the electric motor provided by the manufacturer to ensure compliance with local energy efficiency regulations and energy saving and emission reduction goals.
For example, if the motor of an electric flapper door meets the level 3 energy efficiency (IE3) of GB 18613-2020 standard, then it is considered a high-efficiency electric motor, which means that its energy consumption during operation will be relatively low, which is beneficial to energy saving and operating cost reduction.
It is important to note that the energy efficiency rating of electric motors may change with updates in technology and standards, so the latest national standards and industry specifications should be referred to when purchasing and using electric baffle doors.
