  • Cooling towers play a significant role in every
    industrial process. Just like any other
    industrial equipment, cooling towers are also
    made up of different parts that work together to
    ensure the system functions effectively and
    efficiently. These parts need to be fixed or
    replaced a few times during the entire lifetime
    of the cooling tower. Here are some of them
  • Cooling towers play a significant role in every
    industrial process. When industrial machinery and
    equipment are running at the same time, the
    amount of heat inside the industrial factory
    increases significantly. This increased heat will
    not only pose health and security risks to the
    factory workers and operators, but it will also
    increase the likelihood of industrial machinery
    and equipment to get damaged. Needless to say,
    when the industrial equipment gets damaged, the
    production rate will also decline. Not to mention
    the cost of cooling tower services and of
    repairing or replacing broken parts.

  • Just like any other industrial equipment, cooling
    towers are also made up of different parts. These
    parts work together in order for the cooling
    tower to function effectively and efficiently.
    Aside from the fan motor, water pumps, water
    supply basin, and the draft towers that we have
    already previously discussed, cooling towers also
    include other important parts. These significant
    parts usually need to be fixed or replaced a few
    times during the entire lifetime of the cooling
    tower. These parts include

Drift reducers
  • The drift reducer or eliminator is one among the
    essential parts of the cooling tower. It is
    designed to capture and eliminate large water
    droplets in the air that are caught in the
    cooling tower air steam and to minimize loss of
    process water. The eliminator abruptly forces the
    mist and water droplets in another direction,
    redirecting them to another part of the system
    and preventing them from escaping the cooling
    tower. The moisture is then separated from the
    air and recycled for operational processes.

6
Driveshafts
  • The cooling tower driveshaft is the link that
    connects the input shaft of the gearbox and the
    electric motor. Its main purpose is to transmit
    power from the motors output shaft to the gear
    eliminators input shaft.
  • The driveshaft operates within the harmful
    environment inside the tower. With this, you need
    to pick a driveshaft that is highly corrosion
    resistant. It should also be well balanced or at
    least can be re-balanced whenever needed as it
    has to turn at full motor speed.

7
Cooling tower nozzles
  • The crossflow cooling towers usually come with
    nozzles. These cooling tower elements function by
    harnessing the power of gravity for water
    distribution. The main task of the nozzles is to
    get the warm water that needs to be cooled down
    and deliver it to the fill.
  • The water is usually pushed up to the dispersal
    reservoirs which are located on top of the fill
    media. The gravity will then help the water fall
    down through the fill media via the nozzles which
    are found at the bottom of the reservoirs.

Splash style fill
  • The splash style fill breaks up the moisture. It
    is consists of a few layers of horizontal bars or
    slats. Traditionally, splash style fill media are
    made from wood but there are some modern designs
    that are made from PVC. Nowadays, more and more
    industries are trusting PVC-made splash style
    fill as it is more efficient and it allows better
    and faster heat transfer than the one made from
    wood. This type of fill is more ideal for
    industrial processes that generate dirty or poor
    quality water.

10
How does splash-style fill work?
  • The splash style fill works by spreading and
    breaking the warm water as it hits the bars
    surface. Small droplets are then formed, which
    increases the contact between the water and air.
    This makes evaporation and cooling accelerate
    faster.
  • You can use the splash style fill if you are
    dealing with poor quality water as it does not
    have any channel or parts where debris and dirt
    may be trapped or accumulated. The accumulated
    debris and dirt can reduce the mediums
    efficiency.

Film-style fill
  • The film-style fill material or media is
    basically made from thin sheets of PVC material
    which are positioned close to each other. This
    fill is characterized by its corrugated pattern,
    flat, or textured surface where the water travels
    across.
  • Unlike splash style fill, film-style fill
    material cannot be used for dirty or poor quality
    water as it is made with parts where debris and
    dirt can be accumulated or trapped. Again, when
    debris and dirt from the water build up in the
    fill, the overall performance and efficiency of
    the cooling tower will be reduced. Needless to
    say, this fill material is more suitable for
    cooling clean and quality water. However, if the
    film-style fill material is the only available
    option you have and you need to cool dirty or
    poor quality water, you may choose to use the one
    with wider flutes. Regular cooling tower water
    treatment can also be of great help.

13
How does film-style fill work?
  • The film-style fill material creates a large
    surface area and distributes the water across a
    flat layer. As the hot recirculated water hits
    the fill, it will spread out and form a thin
    film, allowing more contact with the air. This
    enables the heat to evaporate faster, making the
    water cools down at an accelerated rate.
  • The primary function of the fill media, though,
    is to prolong the residence time of cooling
    water, to distribute water evenly, and to
    increase heat transfer area and heat dissipation.
    It helps optimize the cooling process of the
    cooling towers by making the surface area between
    the air and the water flow larger.

14
  • Over time, the fill media will get brittle or
    clogged. Some may lose their film during
    upgrades. When this happens, you need to have the
    fill media replaced. When choosing a fill media,
    you need to consider a few important factors.
    These are the vulnerability to contamination,
    total suspended solids or TSS levels, water
    composition, and intended use.

15
Gearboxes
  • The gearbox is the collection of gears attached
    to the cooling tower motor through the
    driveshaft. This important component transforms
    electrical energy into mechanical energy. It also
    serves as a speed reducer that helps slow down
    the rotational speed from the cooling towers
    incoming motor to the outgoing fan. The reduction
    of speed from the gearboxes acts as a torque
    multiplier. It also helps optimize the
    performance of the fan.
  • If the cooling tower you use does not have a
    gearbox, its motors should be gigantic enough to
    directly handle the fans torque requirement.
    Unfortunately, gigantic and high capacity motors
    are quite heavy and expensive, making it an
    impractical option for many industrial plants.
    With the gearbox acting as a torque multiplier,
    you can be able to make the overall mechanical
    system of the cooling tower more cost-effective
    and at the same time keep the motor smaller.

  • Power industries, companies that run chemical
    processes, and other businesses that operate
    high-capacity production plants, need to use
    cooling towers that are designed with large
    amounts of heat rejection capacity. In order to
    support the cooling towers variable strengths
    and fan speeds, the cooling tower suppliers made
    this element available in different styles and
    reduction rates.
  • The gearbox within the motor should be checked
    regularly to prevent corrosion. When rust starts
    to build up, the mechanical efficiency of both
    the motor and the gearbox will greatly decline.
    Rust build-up, if left unaddressed, can even lead
    to equipment failure. You can either buy a new
    gearbox or hire a professional to renew or
    restore the gearbox.

18
  • Apart from the five important elements of cooling
    towers mentioned above (gearboxes, fill media,
    nozzles, drift reducers, and driveshafts) and the
    other parts we already discussed before (fan
    motor, water pumps, water supply basin, and the
    draft towers), there are other parts that help
    cooling tower function well. This includes the
    reservoir heaters, electric float valves, and air
    intake louvers.
