Strengthening Local Support for Our Valued Customers in Russia & BelarusDear Valued Partners,First and foremost, we want to extend our sincere gratitude to every customer in Russia and Belarus who has trusted Sunlight for high-performance cooling fans and motors over the years. Your continued sup

This week, our factory conducted a series of standardized tests in the wind tunnel laboratory, focusing on the performance of our high-pressure fan when integrated with a radiator into a complete cooling module. The tests evaluated heat dissipation performance at different fan speeds, as well as the

In mining, earthmoving, port handling, tunnel construction and other scenarios, construction machinery operates year-round in extreme conditions: high-temperature exposure, heavy dust, high humidity and strong vibration. Standard off-the-shelf cooling fans often suffer from insufficient airflow, dus

Why High-Efficiency Cooling Fans Are a Core Component in Hydrogen Fuel Cell Vehicles4As hydrogen fuel cell vehicles (FCEVs) gain rapid adoption in commercial vehicles, buses, heavy-duty trucks, and special-purpose vehicles, thermal management has become a critical factor in system reliability and ov

How to Choose the Right Cooling Fan for Industrial Equipment——A Simple Guide for Buyers and Project ManagersIntroductionIn many industrial machines, heat reduces performance and shortens component life. Choosing the right cooling fan helps equipment run longer, safer, and more reliably—without compl

Why Thermal Management Is the Biggest Bottleneck in Modern Charging InfrastructureHigh-power charging infrastructure is evolving faster than ever. Charging systems are becoming smaller, more powerful, and expected to operate continuously under demanding conditions. Yet one problem quietly limits per

Electric vehicles are often praised for being clean and quiet—but behind that calm exterior lies a growing thermal challenge.As power density increases and system integration becomes tighter, managing heat has become one of the most critical engineering issues in new energy vehicles. This is whereEV
