The "ZITS Heat Diffusion System" is an air-cooled management solution that offers numerous benefits and risk avoidance through the installation of a simple air cooling device, providing an extremely high cost-effectiveness. By diffusing the heat generated in the server room into the adjacent large business area, it distributes the load across the entire area's air conditioning units. Machine cooling ensures that the room temperature (up to 28°C) from the return flow path is always maintained, smartly avoiding localized heat buildup in the server room. Additionally, we conduct on-site diagnostics for heat buildup around server racks and throughout the room. We perform an on-site investigation to identify issues and their solutions, along with predictions of the results. There are no costs involved. Please feel free to consult us. 【Features】 ■ Customized design and on-site installation based on various conditions ■ Resolves temperature issues in the server room ■ No need for additional air conditioning units ■ Soundproofing with no sound leakage *For more details, please refer to the PDF materials or feel free to contact us.
