Generally, air flow through the tower is applied in two major methods;
•Natural Draft
•Mechanical Draft
In natural draft type of cooling towers, heat transfer is completely occurred by natural convection via air circulating inside the cooling tower and warm, moist air naturally goes up due to the density difference with respect to the outside air, which produces an air flow through the cooling tower. This type of cooling tower isn’t in our product portfolio.
In mechanical draft type, air fans are used to circulate air through the cooling tower and generally are applied in two methods, induced draft and forced draft which are explained in different types of cooling towers section.
