The "ADHx (Active Rear Door Heat Exchanger)" is a rear door cooling device that achieves maximum heat exchange capability even in low flow environments. With the rapid increase in system processing power due to AI and other technologies, the power consumption and heat generation of server equipment are in a constant state of escalation. As cooling with air alone is reaching its limits, the adoption of water-cooled servers and the auxiliary cooling of air-cooled servers are essential. As a solution, we offer a cooling system using the rear door cooling device and CDU. 【Features】 ■ Cooling capacity: 15kW to 40kW ■ Active type with a choice of 2-row or 3-row chilled water coils ■ Achieves maximum heat exchange capability even in low flow environments ■ The thinnest overall thickness in industry history (201mm) maximizes floor space ■ N+1 redundant EC hot-swappable fans, allowing for replacement work *For more details, please download the PDF or feel free to contact us.
