APC ACRH301S 27 kW In-Row Cooling Unit | Indoor, CE/UL

Keep high-density IT spaces within thermal limits with the APC ACRH301S in-row twin coil indoor unit. Delivering 27 kW of cooling in a 300 mm form factor, it is designed for installations where rack-level heat removal must be close to the load, not pushed to the perimeter. That placement helps maintain more stable inlet temperatures and reduces the strain that comes with uneven airflow. For facilities teams, the value is in precision. In-row cooling responds directly to the heat generated by adjacent equipment, which makes it a strong fit for environments where traditional room cooling leaves hot spots behind. With 200-240 V input and CE/UL certification, this unit is suited to controlled enterprise deployments that require both performance and compliance alignment. This model is built for organizations that measure cooling by uptime, not just capacity. When workloads are dense and service windows are short, a dedicated in-row unit can help preserve thermal headroom, support predictable operations, and protect the infrastructure behind revenue-critical systems.
