The drift leaves the tower at the top.<\/p>\n<p>The crossflow cooling tower can operate with very much lower-than-design levels of flow, as little as 30%. Since the only mechanism pulling down the water through the nozzles is gravity, these towers can provide even water distribution across the fill.<\/p>\n<p><a href=\"https:\/\/www.linquip.com\/equipment\/309\/cooling-towers\">Linquip<\/a> is a proud supplier of cooling tower products, making possible a convenient interaction between the customers and manufacturers.
