STRUCTURE

The cooling tower structure can be manufactured by steel structural elements welded together or by galvanized steel sheets bolted together. At customer’s request, the internal and external surfaces of the cooling tower can be coated or can be manufactured with specific steels.

FAN SECTION

Centrifugal double-inlet forward-curved blade fans, made of galvanized steel, are statically and dynamically balanced. Fans are mounted on a transmission shaft supported at the ends by self-aligning ball-bearings and cast-iron supports. Fans are protected by a fanguard to prevent the entry of debris into the tower.
Motors are mounted on strong adjustable supports made of galvanized steel and protected from atmospheric agents. The motion is transmitted to the fan by trapezoidal belts.

DISTRIBUTION SYSTEM

The water to be cooled enters the module through one or two flanged connections and is uniformly distributed on the filling system through the main pipe and a set of secondary plastic tubes. The nozzles are fixed by means of a threaded connection; their dimensions are factory selected to deliver the design water flow and best performances. The size of the inner diameter prevents any risk of clogging.

FILLING SYSTEM

The filling system is made up of several packs to form a section characterized by a high surface/volume ratio in order to improve the heat exchange capacity of the machine.
Depending on the working conditions, the packs can be supplied in different configurations with different geometries.

FILM filling
ILMED IMPIANTI has designed and developed new “FILMED” filling packs, with an exclusive and very effective design, which work on the “film” principle. They are manufactured in PVC or PP, with diagonal or vertical channels.

HYBRID filling
The TR.U.S.T. (Tridimensional Ultimate Splash Type) filling system consists of modular elements, manufactured in high-thickness polypropylene, which work on the “SPLASH” principle. Ilmed Impianti has designed this special filling system for polluted water with high levels of suspended solids. The modular feature facilitates the handling and cleaning during maintenance. The TR.U.S.T. System is the natural evolution of the traditional grid system, thus defining new levels of strength, ease of installation, performance and durability.

DRIFT ELIMINATORS

The drift eliminators are made of modular elements in PVC or PP sheets.
Their excellent efficiency reduces drift losses below 0.005% of circulating water.

WATER BASIN

The basin collects the process water which can be directly connected to the utilities through the outlet flanges. At customer’s request, each water basin can be equipped with process control instruments, active safety systems (e.g. level controls) and water treatment systems. The basin floor is smooth and inclined allowing for a complete water drainage to empty the basin and to minimize biofouling and proliferation of legionella.
