The invention relates to a cylindrical air condenser (100) comprising a heat exchanger (110) which has a cylindrical or polygonal shape that develops in a vertical direction (Z) from a base or bottom to a top, and a suction device (120) provided with a motorized fan (121) housed in a frame (122) arranged on the top of said heat exchanger (110). The cylindrical condenser (100) further comprises a distributor element (130), housed inside the heat exchanger (110) coaxially therewith, said distributor element (130) comprising a plurality of conduits (131a, 131b, 131c, 131d, 131e) arranged coaxially one to the other, said conduits (131a, 131b, 131c, 131d, 131e) having a progressively increasing height from the top to the bottom of the heat exchanger (110) and a progressively decreasing transversal dimension, the configuration of the distributor element (130) being such that, starting from the top towards the bottom or base of the heat exchanger (110), a plurality of through openings (A1-A6) whose areas are nominally identical are defined therein in the vertical direction (Z).

METHOD OF CONTROLLING WATER CONSUMPTION FOR ADIABATIC COOLING SYSTEMS
A method of controlling consumption and delivery of water in plants with disposable water flow and more particularly in adiabatic cooling plants fed with disposable water and provided with economizer devices.
An economizer device for detecting the passage of a liquid is disclosed, comprising an electrically non-conductive main body and a passage channel for said liquid. The passage channel is also provided with a narrowing portion. The main body includes also a pair of holes made on opposite sides relative to said passage channel. The device comprises also a pair of conductive elements arranged on opposite sides relative to said narrowing portion, and each conductive element has a passage for the liquid. The device is positioned with a vertical central axis and perpendicular to ground, while the holes made on body are arranged at different height relative to the vertical axis; moreover two electrodes are inserted in said holes, so that the electrodes are fully buried in the device main body. Finally said conductive elements are provided with a conical portion converging to a cylindrical circular portion.
