EMERITUS

8 9 REDUCED WATER CONSUMPTION Using EMERITUS ® dry coolers and condensers as an alternative to the traditional cooling towers and evaporative condensers has an important advantage in water consumption. BETTER PROTECTION To ensure maximum protection of the heat exchanger surfaces, Emeritus ® uses water with these characteristics: EU Directive 98/83/EC on drinking water EMERITUS ® specification Conductivity [µS/cm] <2500 <800 Fixed residues [mg/l] <1500 <500 Chlorates [mg/l] <250 <100 Sulphates [mg/l] <250 <50 Hardness [°f] <50 4-6 Indicative softener ratio (max) - 7 pH 6.5 - 9.5 6.5 - 8.0 ANNUAL WATER CONSUMPTION (INDUSTRIAL PLANT) HYBRID COOLER COOLING TOWER Emeritus Up to 95% Reduced water consumption compared to cooling towers TWO FURTHER IMPORTANT PROTECTIONS: WET WORKING TIME Emeritus ® can work in wet operation for a different number of hours per year for each configuration: To make sure that the water is always within the pre-set limits, Emeritus ® has 2 sensors which constantly measure these parameters: • pH • electrical conductivity The data are memorized by the control system and in the event that the threshold limit is exceeded the controller sets off an alarm, the water supply is then interrupted. Sensors to check the quality of the water ACTIVE The severe tests carried out in salt spray conditions showed that the ALUPLUS ® fin is TWICE as resistant as ALUPAINT ® solution. ALUPLUS ® : a new magnesium- aluminium alloy coated with a special paint treatment to give strong protection and resistance to corrosion.
