Technical Description

Axial cooling is appropriate for a variety of cold storage applications, including chilled containers, cold storage boxes (cold storage fan), and incubators. Low temperatures in cold chain transportation and warehousing can readily cause equipment condensation and unstable operation. Because of its wide temperature adaptability, the PA3N250B24H can start properly at temperatures as low as -25°C, efficiently circulating air within the unit to prevent localized temperature discrepancies and items from freezing or spoiling. In the data center, it works with fan wall units and server in-row cooling systems. Data center servers create a lot of heat while running; thus, in-row cooling requires accurate airflow distribution and effective heat dispersion. The small shape of this axial fan (280×280×80 mm) makes it easy to integrate into in-row cooling equipment. Its high static pressure and vast airflow volume quickly remove heat from server clusters. When combined with adaptive speed management, which dynamically adjusts fan speed based on server demand, it provides excellent cooling while decreasing energy usage. This efficiently reduces the data center's PUE value and provides a strong thermal management defense for steady server operation.
