Packing Details

The items are frequently utilized in Cloud Date Center server cabinet active cooling systems. CPU/GPU single-chip power consumption has surpassed 350W as server power density continues to increase, and single-cabinet power density has changed from the conventional 5kW to 15–30kW. The demands of high-density deployment can no longer be satisfied by conventional natural convection cooling. With a medium-to-high static pressure of 502 Pa and a large air volume output of 2175 m³/h, DC backward curved centrifugal fan can precisely direct cold air to the CPU and memory areas to ensure heat exchange efficiency under large-scale IT loads. It can also successfully overcome the airflow resistance created by cabinet air inlet and outlet panels, high-density deployed server front and rear panels, dust-proof filters, etc.
With its high heat dissipation density, stringent noise compliance, high reliability, and lack of maintenance, PB3N310B48L is made to satisfy all the demands of data centers. At the moment, it is the recommended option for green data center cooling systems and high-density server cabinets. PBM specializes in the development and production of superior EC/DC fans and clever airflow solutions. To satisfy the various demands of computer room infrastructure, PBM can offer a range of specialized services.
