Chilled door technology is a rack-level cooling solution using rear door heat exchangers (RDHx) to directly remove heat from servers via chilled water loops. This method eliminates room overcooling and allows higher server density without increasing HVAC loads. Its modular design, smart fan control (via Redfish), and compatibility with air- and liquid-cooled systems make it ideal for AI data centers, telecom infrastructure, and hyperscale cloud facilities. As sustainability becomes a priority, chilled doors offer a scalable, energy-efficient way to reduce carbon footprint and enhance data center performance.
