Fig. 7 shows an elevation and Fig. 8 a section of theRow tube as applied to evaporative condensers. With the Fraser horizontal tube, Figs. 9 and 10. water is takenfrom a rectangular tank and passed along a perforated galvanizediron pipe immediately above the condenser tube. For further dis-tribution on each of the lower tubes, strips of galvanized iron ex-tending the whole length are fixed on the underside of eachtube by means of iron straps or brass spring clips. When fans are used with this type of condenser a curvedtrough is fixed under each tube on the lowest tube of each row,turning the water ofY into the side tanks. This prevents it fromdropping on to the fan blades, and the disturbance of the wateron the fa
