Description

The trickle built-in unit is preferably known

Way made from a thermoplastic or from a thermosetting plastic.

The invention relates to a trickle installation unit for 50. The invention is described below with reference to a gas-liquid contact device, in particular drawing, for example. It shows
their cooling tower, with a large number of parallel Fig. 1 is a plan view of a trickle installation

arranged, upright, elongated struts, that is, according to the invention,

which are connected to one another and of which in FIG. 2 an end view of the unit according to FIG. 1
