1. Medium- and high-voltage frequency converters generate a large amount of heat during operation. Without timely heat dissipation, the equipment may overheat, which impairs its normal operation and service life.
2. When customers conduct after-sales service or install fans at terminals, on-site personnel are required to assemble the housing, protection net and air guide ring separately. This not only increases labor costs for installation, but also brings the risk of collision damage to individual fans during transportation.
