CAIRplus air-handling units for airflow from 3,000 to 23,000 m3/h are now available with adiabatic cooling. These models cool extracted air up to the saturation point. The cold produced by evaporation is then transferred to the supply air via energy recuperation. A downstream-installed cooling coil then regulates the temperature of the cooled air supply and its relative humidity to the desired level. The new, directly-sprayed EcoTwincool double-plate heat exchangers enable energy-saving adiabatic cooling. Since it is not necessary for downstream chillers to run continuously, a reduction of 60% of annual energy consumption can be expected, says the manufacturer. — GEA Air Treatment GmbH, Herne, Germany
