The evaporation assembly module comprises an evaporation element, a pipe having at least one fluid outlet and configured for wetting at least a portion of the evaporation element by passing fluid through the fluid outlet, and a support structure configured for holding the evaporation element in a suspended position. The method includes connecting the pipe to the evaporation element and subsequently suspending the pipe and the connected evaporation element to the support structure, in a suspended position.
