Difference between the counter flow and cross flow cooling tower

New cooling tower PP fill is widly used in the cooling tower industry.

The grid fill is the result of an extensive optimization of the lath width, the blockage area ratio and the lath layout; The water droplets, splashing on a well drained lath, break in a large number of very small droplets, inducing large heat exchange surface. Blockage area ratio and lozenge layout is the optimized compromise between the pressure drop and the probability of large droplets to hit the laths. The laths height has been selected to transfer the load to the supporting spacers using minimum material quantity. It may be used as well in Counterflow as in Crossflow cooling towers, mechanical or natural draft. It is well adapted to any water quality, even without water treatment, when the fouling risk cannot be determined, in particular with seawater.

Spiral Target Cross Flow Cooling Tower Spray Nozzle is made by PP material, and assembled by several parts. It is widely used for the counterflow cooling tower. Spiral Target Cross Flow Cooling Tower Spray Nozzle help ensure a uniformly delivery of water over the cooling tower fill. Uniform water distribution at the top of the cooling tower fill is essential to achieve proper wetting of the entire cooling tower infill surface.

The fan stack is an essential part of the cooling tower as well as a part of the propeller fan, mitigating pressure loss produced by high input air speed. Fan stacks for cooling towers are made from layered laminated polyester, and they have a double-coat design. Their inner smooth surface allows for the fast removal of air. The outer surface provides high strength and resistance against climatic conditions and the operation of cooling towers. The shape of the classical cylindrical fan stack contributes to lower noise and vibration not only of the fan itself, but the whole cooling tower.
