- Industrial Application Cases
場合 1: Heat Dissipation Upgrade for Schneider Inverters
A factory frequently encountered overheating alarms on Schneider ATV61 series inverters. The original sleeve-bearing fans had short lifespan and insufficient airflow.
解決: Replaced with Delta FFB1424VHG double ball bearing fans. Airflow increased by 30% and service life extended to 50,000 時間.
Result: Inverter failure rate reduced by 80%; maintenance interval extended from 3 months to 2 年, saving approximately RMB 12,000 in annual maintenance costs.
場合 2: Server Cooling Optimization for Data Center
High-density servers in an edge computing data center suffered from overheated CPU and performance degradation due to inadequate original cooling fans.
解決: Installed 2 sets of 4-wire PWM controlled FFB1424VHG fans at the rear of server enclosures, linked with the server temperature control system.
Result: CPU temperature dropped by 12℃, system performance improved steadily by 15%. Energy consumption and noise were also reduced via PWM speed regulation.
場合 3: Cooling for Medical MRI Scanner
Poor heat dissipation on the power modules of an in-hospital MRI scanner caused frequent downtime and disrupted medical services.
解決: Adopted customized long-life version (-F00) FFB1424VHG fans and optimized air duct layout for uniform heat dissipation.
Result: Equipment operational stability improved by 95%, downtime reduced by 90%. The service life of power modules was prolonged and maintenance costs decreased.
FFB1424VHG is a balanced high-performance industrial fan from Delta FFB series. Featuring large airflow, high air pressure and long service life, it is widely applied in industrial automation, power electronics, data centers and other fields.
Select the proper model according to actual requirements on voltage, airflow, noise and service life, together with corresponding suffix versions (-R00/-F00/-EP). Follow installation specifications and perform regular maintenance to achieve optimal cooling performance and maximum service life.
