IRRIGATOR MADE OF CORRUGATED PVC SHEET FOR COOLING TOWERS

The irrigators made of corrugated PVC sheets are used in the fan and chimney type cooling towers and are designed for cooling of technologic circulating water.

The irrigator block is a set of vacuum-molded corrugated sheets (with dimensions 2400 500 mm and a height of corrugation - 23.5 mm), which are placed with interchange of sheets with corrugations of opposite directions.

The irrigators are produced according to technical specifications 厶 25.2-20054481.001-2001.

力-23 Type

The cooled waterThe cooled water is sprayed on top of the irrigator blocks and under the influence of gravity flows down mainly as a film on the corrugated surface of the sheets. The intense water cooling is ensured through flowing of water film downwards in the air counter flow.

The irrigators made of corrugated sheets provide the largest contact surface for heat exchange of water with air at aerodynamic resistance, which is weaker in comparison with the ones of irrigators of other types, thus the highest cooling effect of water is achieved.

The assembling of irrigator blocks is simple, convenient and takes little time, it is performed at the installation site. Transport costs are minimal (10-12 times less in comparison with the costs of other types of irrigators).
