Smardt Air

Dual Cooling Source Fan Wall

45–250 kW (13–71 TR)7,100–35,300 cfm (12,000–60,000 m³/h)

The Smardt AIR Dual Cooling Source Fan Wall has two ways to cool. Its first choice is free cooling: warm water from a cooling tower (open or closed circuit) or a dry cooler, with no compressor running. When outdoor conditions can't carry the full load, a built-in compressor circuit makes up the difference. In facilities that also run liquid cooling, the warm water loop can provide full free cooling for the liquid-cooled load and partial free cooling for the air-cooled load. Two versions are available: the standard fan wall for 10–20 kW per rack, and the thin fan wall for 40 kW per rack and above.

Key Performance Advantages

Two Cooling Sources

Warm water free cooling first, compressor cooling when needed, in one unit. Suits air-cooled and hybrid air/liquid data centers.

High Efficiency

EC fans and a variable speed scroll compressor keep part load efficiency high. Hydrophilic aluminum fin, copper tube coils improve heat transfer.

Modular and Fast to Deliver

Configurable for different IT loads, in standard and thin fan wall versions. Modular design shortens lead times.

Precise Control

PID control holds temperature within ±1°C (±1.8°F) for a stable IT environment. RS-485 communication comes standard.

Maintain While Running

Controls sit apart from the airflow, all service is from the front, and maintenance can be done while the unit operates.
