- Industrial Application Cases
Случай 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.
Решение: Replaced with Delta FFB1424VHG double ball bearing fans. Airflow increased by 30% and service life extended to 50,000 часы.
Result: Inverter failure rate reduced by 80%; maintenance interval extended from 3 months to 2 годы, saving approximately RMB 12,000 in annual maintenance costs.
Случай 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.
Решение: 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.

Poor heat dissipation on the power modules of an in-hospital MRI scanner caused frequent downtime and disrupted medical services.
Решение: 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, широко применяется в промышленной автоматизации, 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.
