4 Emeritus configuration The STANDARD configuration (Figure 1) sprays water onto the heat exchangers; non-evaporated water runs off them and is recovered in a tank, from where it is recirculated through the adiabatic panels. This system minimizes the consumption of water. On some models, the hydraulic group is equipped with a bypass manual valve of the pH and conductivity probes. The bypass manual valve must be normally closed and all the water flow shall flow trough the probes. In case of low pressure or low water flow to the spray/adiabatic system, the valve shall be progressively opened to have a partial bypass of the probes, reducing the pressure drops Figure 1 : Diagram of STANDARD EMERITUS operation IN: water supply line EV: solenoid valve EV SC: drain valve V1: modulating valve P: pump FL: flowmeter PR1: spray pressure probe non-return valve UV Lamp pH and conductivity probes Spray Adiabatic Panels WATER FROM COIL tank pH and conductivity probes
