Cross Flow Cooling Tower
Crossflow Cooling Towers
is design in which the air flow is directed perpendicular to the water flow. Air flow enters one or more vertical faces of the cooling tower to meet the fill material. Gravity water distribution allows smaller pumps and maintenance while in use. Water flows (perpendicular to the air) through the fill by gravity. The air continues through the fill and thus past the water flow into an open plenum volume. Lastly, a fan forces the air out into the atmosphere.
Crossflow Cooling Towers typically lower initial and long-term cost, mostly due to pump requirements. A distribution or hot water basin consisting of a deep pan with holes or nozzles in its bottom is located near the top of a crossflow tower. Gravity distributes the water through the nozzles uniformly across the fill material. Non-pressurized spray simplifies variable flow.
