The design of cooling tower`s filler unit, consisting of inclined-corrugated contact elements, and made of polymer material, is developed and described in this research paper. The experimental studies were conducted to determine the efficiency of cooling the circulating water in the proposed cooling tower. The authors obtained the results of evaluating the heat-mass transfer efficiency coefficient of cooling tower, when changing the mass flow rates of liquid and gas phases. The research results showed that the highest efficiency of cooling the circulating water is observed at relatively low irrigation densities equal to 15-25 m3/(m2·h), while the heat-mass transfer efficiency of cooling tower achieves 72%.The use of non-metal materials as the main elements of cooling tower allows to abandon the use of chemical reagents against bacteria and microorganisms in favor of circulating water ozonation method.
