BP20 - direct fan
| Address: Ben Luc District, Long An Province | |
| Project Summary: A textile and dyeing enterprise in Long An has replaced the belt-driven fans with higher-efficiency direct drive fans. | |
| Year of implementation: 2019 | |
|
Status before implementation The ventilation fan system for ventilation was using belt-driven ventilation fans (capacity of 1.5 Hp, airflow of 33,000 m3/h).
Ventilation fan The belt transmission gave low efficiency due to loss of energy caused by electric wire heating, friction, elongation of belt, high slippage coefficient. As a result, there is a reduction in efficiency of the transmission from the electric motor to the propeller and reduction of its service life. In addition, the noise effect of the belt transmission was greater than that of the direct drive with the same capacity. |
Result The factory has replaced nine (9) old fans with new direct drive fans.
New fan (direct drive) The new fan has a capacity of 1 Hp (airflow of 45,000 m3/h) and helps reduce the power consumption > 33%. |
