EMERITUS

4 5 Water injected direct onto the coil through the spray system Non-evaporated water collected in a tray Collected water passed through a UV lamp Water sent to the adiabatic panels Excess water on the adiabatic panels disposed as drain water HOW WORKS Emeritus ® technology combines the spray function with adiabatic precooling. In this way the system exploits the synergy between two effects: adiabatic humidification and evaporation of water on the coil. Available configurations: 1 Emeritus ® recommended system to guarantee maximum performance 2 Adiabatic System suitable for systems without water treatment 3 Water Spray Evolution water nebulization in the opposite side of the air direction, suitable for covering peaks of temperature 4 Spray System Evolution water atomization directly on the coil, suitable for covering peaks of temperature only available as part of Emeritus ® complete solution OPERATION The graph compares the performance of the new EMERITUS ® system with the performance of the DRY version at DT1=5K. The combined Spray System + Adiabatic Systemmode operates as follows: VERSATILITY OF THE SYSTEM: Emeritus Emeritus The Emeritus ® system is patent pending.
