Technical Description

The 250mm EC axial fan PA3N250B2EH is specifically designed to satisfy the ventilation and heat exchange requirements in every situation in the refrigerated cold chain by utilizing key benefits like EC stepless variable-speed energy efficiency, low-temperature weather resistance, and long-term stable operation. It covers mobile cold chain storage cabinets, low-temperature turnover storage units (cold storage fans), fresh produce cold chain sorting stations, and temperature-controlled packaging workstations. It is extensively utilized in small and medium-sized fresh-keeping cold storage facilities and freezer rooms for evaporator cooling and uniform air circulation within the storage space. Additionally, it works well with air-cooled chillers, compact condensing units, refrigerated containers in cold chain transportation vehicles, portable low-temperature storage equipment, and back air circulation in supermarket upright freezers and island freezers. With its low power consumption and energy efficiency, this axial fan can regulate its speed intelligently in response to low temperatures. It provides consistent airflow without frost accumulation in conditions with high humidity and moisture. It prolongs the shelf life of food items by guaranteeing constant interior temperatures and thorough cooling coverage. In applications involving equipment cooling, temperature-controlled circulation, heat exchange, and cold chain refrigeration, it is the best option for replacing or upgrading fans.
