Feature
EVAPCO SOUTH AFRICA Evapco is proud to be the first to develop a closed-circuit cooler with patented combined indirect and direct cooling technology . The pump is energised , and water circulates up to the water distribution system .
The large orifice EvapJet nozzles evenly distributes water as a thin film over the extended fill surface for maximum cooling efficiency . Simultaneously , the fan system moves large volumes of air through the unit in the opposite direction of the falling water .
The air and water contact directly across the fill surface , whereupon a small portion of the spray water evaporates ; the warm and saturated air is then discharged from the unit , removing heat from the system .
The spray water exits the fill section as a cooled fluid where it is collected by the redistribution basin for even soaking of the full footprint coil . The hot process fluid enters the coil through the bottom coil connection ( s ). The heat load is rejected to the circulating water that cascades over the coil surface by means of sensible heat transfer .
The new ESW4 was designed to maximise capacity and optimise energy efficiency in Evapco ’ s single largest closed circuit cooler cell available . It was specifically developed for high tonnage applications , where the end user requires the lowest energy consumption on the fewest number of units and fans . The ESW4 further offers the highest number of models and box sizes in the industry and is CTI Certified in performance .
