Liebert Direct Evaporative Free Cooling Units offer the lowest large-scale thermal management system efficiencies possible. Advanced algorithms and unique design features provide a level of control not easily achievable on competitive systems. Liebert iCOM™ control algorithms continuously process readings from the rack inlet sensors to ensure optimal airflow through the system, while supply air sensors are used to control the unit cooling capacity. Dampers and exhaust fans are automatically adjusted by the Liebert iCOM unit control, which also harmonizes the operation of multiple air handling units to eliminate conflicts in temperature, airflow and humidity.
