Maintenance of Cooling Towers
Cooling towers are the machinery which cools off any building, which ultimately
helps in its long running. They are actually heat exchangers that utilize water as
well as air to transfer heat from air-conditioning mechanism to the outdoor
environment. Generally, they are used to take out heat from the condenser water
parting a chiller. Cooling towers are more often than not located on rooftops or
else other outdoor sites. The Director of Khatana Enterprises offering cooling
towers maintenance services states that for the reason that they are often out of
sight, they are over and over again neglected by operation-and-maintenance
technicians, resulting in poorer cooling-system efficiency. We will go on the
expedition to help you adopt most excellent practices for the proficient operation
along with maintenance of cooling towers.
Kinds of Cooling Towers
There are two fundamental types of cooling towers, open as well as closed
(sometimes called direct plus indirect).
Open (Direct) Cooling Towers
Open cooling towers render the condenser water coming from the chiller plant in
a straight line to the atmosphere. This lukewarm water is sprinkled over a fill in
the cooling tower to augment the contact area, as well as air passes through the
fill. The majority of the heat is eliminated by evaporation. The cooled water left
over subsequent to evaporation drops into the gathering basin and is come back
to the chiller's condenser.
Closed (Indirect) Cooling Towers
A closed cooling tower mixes warm water from the chiller plant from side to side
of the tubes located in the tower. In an indirect tower, the cooling water does not
move toward in making contact with the outside air. Water that travels only
within the cooling tower is sprinkled over the tubes and a fan blows air crosswise
the tubes. This chills the condenser water inside the tubes, which is then re-mixes
to the chiller plant.
Cooling tower maintenance should take in more than just a twelve-monthly
inspection. Sticking to a defensive maintenance schedule will lend a hand to
reduce the growth of bacteria like Legionella and put off premature failures.
Below is a fundamental to do list to facilitate to maintain your cooling tower.
• Ensure all apparatus is operating properly as well as safely.
• Test out for excessive vibration in motors, fans as well as pumps.
• Test out for loose connections, decomposition, leaks, corrosion, etc.
• Test out all belts and pulleys, fine-tune accordingly.
• Open cooling towers ought to have the water weathered for suitable
concentrations of suspended solids along with chemistry.
• Test out motor supports along with fan blades for extreme wear and secure
• Scrutinize motor alignment in addition to coupling.
• Closed towers ought to have the blow down attuned and chemicals added as
• Give surety that all bearings are greased per manufacture’s suggestion.
• Inspect fan blades for fractures and clean as required.
• Make sure the condition of the motor from beginning to end of temperature or
• Clean the dregs that have mounted up on the basin.
Dregs can absorb handling chemicals making you over expend on these products.
Adding more than compulsory can have a massive impact on your on the whole
budget. Having the residue removed from the basin can extend or do away with
the likelihood of structural rust. Cleaning the basin of the tank will also get rid of
the risk in the augmentation of Legionella. Chemicals such as chlorine can give
support in killing the bacteria; however again how efficient is the chemical if it is
being engrossed by the residue.
When your facility’s cooling tower is suitably maintained it permits the tower to
carry out at its most favorable efficiency stage. Not only does it put away the
capability operating time, it also has a financial savings. This is because the
capability will not have unanticipated shut downs for significant maintenance. The
program that you put in place for your tower provides it the capacity to operate
at a further energy efficient point. The already elevated horsepower fans will not
have to dart longer or harder than typical to receive preferred cooling
temperatures. Having a usual maintenance calendar will enhance the long life of
your plants cooling system.
What category of system or timetable have you put in place for your ability? Are
the fallouts what you had anticipated? If not, how have the alterations you made
impacted the basic result of your maintenance timetable?
