CRV4 is an advanced in-row precision cooling module with 300mm/600mm widths, deployed between standard IT racks in cold/hot aisle containment setups. It integrates inverter compressors, electronic expansion valves, backward-curved EC fans, and the iCOM intelligent control platform.
Eliminates high-density cabinet hotspots and air recirculation issues without the airflow inefficiencies of raised-floor downflow units, preventing short-cycling and driving down the power usage effectiveness (PUE) of mission-critical compute rows.
Enterprise and hyperscale cloud data centers, modular aisle containment solutions, edge computing edge facilities, and critical telecommunication switching centers.
