1. Fan

The vertical-axis fan, operating in the suction system forces the air flow through the cooling tower.

The efficiency of the fan can be regulated by changing fan blade angle.

2. Mist eliminator

The eliminator is positioned above the water distribution system in order to drastically reduce the force driving droplets outside the cooling tower.

The eliminator should be characterised by high mist elimination efficiency and minimal air flow resistance.
 

3. Threaded connections

They were designed to supply hot water to the cooling tower and to channel the cooled water.

4. Water distribution centre

It constitutes of the pipe systems including spray nozzles. The water distribution system was designed to evenly distribute water to the wet deck surface.

5. Supporting structure of the wet cooling tower

It is made of stainless steel. Its walls are made of glass-polyester composites.

The use of corrosion-resistant materials allows the cooling tower to be used for a long period of time.

The viewing window located in the casing was designed to monitor the operation of the cooling tower.
 

6. Wet deck surface

It is placed on the frame made of stainless steel. The task of the wet deck surface is to obtain as much contact surface between the cooled water and air as possible.

7. Shutters

Installed in inlet ports, facilitate air intake to the fan cooling system and protect it against sucking foreign objects.

8. Basin

It is made of glass-polyester composites and is designed to collect water flowing through the wet deck surface.

The valve installed in the wall of the basin was designed to make-up water loss.
 

Optional fittings

The wet cooling system can be optional equipped with:

• To control the RPM of the fan as a function of cooled water temperature it is possible to use a frequency converter.
  • The use of a frequency converter as a function of cooled water temperature to control the RPM of the fan, apart from ensuring constant water temperature and electricity efficiency allows for the reduction of noise emission (especially at night, when ambient temperature falls down and the motor can operate at lower speeds). Noise reduction by approx. 10+/-2dB(A).
• Fan and water noise silencers (sound-proofing mat).
• Multispeed motors.
• Water treatment facilities.
