Closed cross-flow cooling tower fan with large blades fan silent type, making the outlet of the cooling tower quieter. Using a gravity tank-type water distribution. Broadcast spray water into the pool-type basin, then under gravity through the nozzle, spray in the following heat transfer fluid coolers fillers and heat exchangers. Through the heat exchanger, the natural into the bottom drain pan. So the relative counterflow fluid coolers, ZXZ-H series cross flow cooling tower closed lower noise. No water catchment tray trickle "buzzing" sound. Cross-flow cooling tower can be more than one closed assembled together side by side, with the cooling tower, compared with a smaller footprint. Therefore, the cross-flow cooling tower is more suitable for closed: Noise demanding smaller footprint occasions.
