Question 1

What are the core thermodynamic cooling capacities, Sensible Heat Ratio (SHF), and electrical airflow metrics of the Vertiv Liebert CR060?

Accepted Answer

Engineered for high-density compute environments, the Vertiv Liebert CR060 (CRV4 series) delivers a nominal total cooling capacity of 62.6 kW under standard return air conditions (37.8°C DB / 20.8°C WB) with a Sensible Heat Ratio (SHF) exceeding 0.98, virtually eliminating latent cooling waste. The unit integrates a variable-speed DC inverter scroll compressor and high-efficiency backward-curved EC centrifugal fans, driving an airflow capacity of 10,250 m³/h with dynamic modulation tailored to real-time rack thermal loads. Operating on 380-415V/3Ph/50-60Hz utility power, the inverter system provides soft-start functionality with locked rotor amp (LRA) near zero, mitigating inrush current and optimizing data center PUE.

Question 2

How does the CR060 mechanically integrate into server rows, and what multi-unit teaming (Teamwork) protocols are supported?

Accepted Answer

The Liebert CR060 features a 600mm wide in-row footprint measuring 600mm(W) × 1100mm(D) × 2000mm(H) with a net weight of 340 kg, matching standard 42U/47U server racks and integrating seamlessly into hot/cold aisle containment systems. Managed by the Liebert iCOM controller, it natively provides RS485 and Dual Ethernet ports supporting Modbus RTU/TCP, SNMP v1/v2c/v3, and BACnet-IP. Up to 32 units can be networked via CAN-Bus or Ethernet for Teamwork operation, executing dynamic load sharing, scheduled duty-rotation, and N+X cascading redundancy. In the event of a network loss, individual units automatically revert to autonomous failsafe setpoint operation to prevent thermal runaway.

Question 3

What electrical protection, voltage tolerance, and wide-ambient adaptation mechanisms safeguard the Liebert CR060 against site anomalies?

Accepted Answer

Engineered for mission-critical reliability, the CR060 features an optional integrated Automatic Transfer Switch (ATS) accepting wide voltage fluctuations (nominal ±10%). The internal electrical cabinet includes Class C / 40kA surge suppression along with real-time phase-loss, reverse-phase, under-voltage, and over-current protection interlocks. For extreme climates, the unit interfaces with Vertiv variable-speed outdoor condensers (e.g., LSF series), utilizing low-ambient kits to sustain full-capacity operation from -40°C to +45°C ambient temperatures. Condensate management incorporates dual drainage pumps (lift head ≥ 4m), digital water leak detection ropes, and non-volatile memory for automatic cold-restart upon power restoration.
