Overview
The CoolIT AHx180 is a self-contained liquid-to-air coolant distribution unit rated for 180 kW of cooling at a 15 C approach temperature difference. Unlike the liquid-to-liquid CHx line, it rejects heat directly to room air, so it needs no facility-water connection - making it suitable for colocation and brownfield data centers that cannot add building liquid infrastructure.
The AHx180 uses two 2N-redundant pumps and four N+1 fans in a slim two-rack footprint, with all-stainless-steel piping and integrated flow, pressure, temperature, humidity, coolant-level and leak sensors. Group control handles up to 20 units, and monitoring is exposed over Redfish, SNMP, TCP/IP, Modbus and BACnet. It delivers over 1.5 LPM/kW (270 LPM at 40 psi) for high-TDP AI and HPC servers.
Key Benefits
180 kW liquid-to-air CDU · no facility water required · 2-rack footprint · 2N pumps + N+1 fans · 270 LPM at 40 psi · Redfish / SNMP / Modbus / BACnet · group control to 20 units.
Applications
Direct liquid-cooled AI, HPC and high-density enterprise racks in colocation and brownfield data centers without facility water, and deployments seeking a compact two-rack liquid-to-air heat-rejection unit.
