Cooling tower fan

What is a Cooling tower?

The cooling tower is an equipment used to cool a large amount of process water, by producing artificial rain or thin film of hot water to increase the surface area of the hot water and then exposed it to the air which may flow naturally or by the means of mechanical powered fan called cooling tower fan.


How does the cooling tower works?

Cooling towers work on the principle of evaporation where a high-energy molecule leaves the system and the resultant energy of the remaining molecules reduced.


How cooling tower fan works?

The working principle of the fan is the same as an aeroplane.
The only difference is in-plane lift use to push the plane upward whereas in fan lift used to through the air. Cooling tower fans also use the same principle as an aerofoil. And because it operates 24 Hours and has to displace a large amount of air, therefore, it is a must-use most efficient airfoil in the fan blade. Know more about the cooling tower fan here.


What Is an Evaporative cooling tower fan?

Cooling towers work on the principle of evaporation, so the fan used in such a tower called an evaporative cooling tower fan. Know more about cooling tower fans here.


Cooling tower fan blade angle calculation?

The blade angle of any fan cannot be, calculated it is an outcome of the fan design and it can be, selected from the fan performance curve as per the required performance of fan (i.e. airflow, static pressure, RPM, and power).


Cooling tower vibration cause and solution

The source of vibration in a cooling tower is a fan, and the biggest reason for fan vibration is an imbalance, despite this fan tracking, higher tip clearance, and various frequency resonance can also cause high fan vibration. Imbalance and tracking can be addressed at the site, whereas tip clearance is the property of fan shroud, whereas other frequency related issues need high technical know-how to find the cause. And these issues can solve by changing the number of blades in a fan or the blade profile. At Maya, we strictly follow the ISO 1940 for fan balancing and each cooling tower fan/Blade statically/Blade moment balance and hub are dynamically balance to avoid any such occurrence.


Reason for cooling tower fan failure?

In general FRP cooling tower fans are robust and strong enough to carry any load if the structural design is OK. So the reason for fans failure could be – Manufacturing fault. Improper design. Improper selection – This is the main reason for failure as per our observation. Most of the manufacturer having limited blade design. So they force those blade for all the application and duty points. But over a while cooling tower pressure increase very much, and the old fan blades are not able to fulfil the duty point and prone to fail )


What are various cooling tower operating cost?

Electricity for fan and motor.
Makeup water.
Cooling tower water treatment chemical.
Maintenance cost.
Mainly cooling tower jobs include cleaning of different components and maintenance of fan significantly reduced by installing the robust fan.


Effect of the fan on cooling tower water temperature!

Initially during cooling tower design fills media is having a maximum effect on the water temperature but once the tower is installed and working the fan is the only device that affects the performance of the tower.


What is the various application of cooling tower?

The cooling tower in the power plant is the largest equipment by space. A cooling tower for ac or HVAC Cooling tower with any types of machine which need cold water to maintain temperature.


How to measure cooling tower fan performance?

For performance measurement, cooling tower institute code 143 are used. We recommend cooling tower cold water temperature should be considered while comparing two different fans, in case of common sump rainwater temperature should be considered.

Heat Excnahegr fan

Major mistake observe with heat exchanger fans!

  • Some OEM having their own design or having outsourced design so they try to fit it and all the solutions.
  • The same fan is altered for a range of diameter.
  • The economy of the fan is prioritized over efficiency.
  • A cheaper PVC moulded fan is used.
  • the proper air inlet is not provided.
  • fan with less twist is prefered due to transport cost reduction.

Heat exchanger fan selection and its impact?

The fan is a critical part of the exchanger and it should be considered with seriousness, in a large heat exchanger mostly the fan should be of FRP blade but a small heat exchanger with a fan may have a PVC fan it is not the best fan but still perform good and remain economical.

 

 Heat exchanger working principal?

 

 The fluid caring heat from the source is sprayed on the higher surface area such as –

 

  • Heat exchanger tubes.
  • Heat exchanger plates.
  • Heat exchanger coil.
  • Heat exchanger fins.
  • Cooling tower fills splash bars, etc.

 

And the high volume of air is thrown against this large surface to carry the heat from it, and heated fluid is cooled to the desired level.


What is the factor impact Heat exchanger effectiveness?

During planning and design many factors can affect the heat exchanger performance but once it is installed and working only atmospheric conditions and its fan can impact heat exchanger effectiveness.


What does a heat exchanger do?

As the name suggests it exchanges heat from one medium to another most of the time it diffuses process heat in the environment.


We receive an imported heat exchanger with a fan, now where to buy these fans locally?

The source of vibration in a cooling tower is a fan, and the biggest reason for fan vibration is an imbalance, despite this fan tracking, higher tip clearance, and various frequency resonance can also cause high fan vibration.
Imbalance and tracking can be addressed at the site, whereas tip clearance is the property of fan shroud, whereas other frequency related issues need high technical know-how to find the cause.
And these issues can solve by changing the number of blades in a fan or the blade profile.

All the heat exchanger manufacturer buy the fan from Fan Company (exemption maybe there) so even if you approach the OEM fan is going to come from a different manufacturer, so it is better for you to search for a heat exchanger fan not with the name of the manufacturer of the equipment.

We manufacturer all kinds of FRP heat exchanger fans which can offer 15 – 35% power saving over your existing fan Click Here to contact us.

Air Cooled Condenser Fans

What is an air-cooled condenser?

It is an Air-cooled Heat Exchangers. It is a heat rejecting device that used to cool the hot process fluid and dissipate heat in the environment.

In this heating equipment sprayed over a large area by the use of fins. And then airflow passed to this surface to take the heat out. this equipment is also known with the following names:

 

  • Air Fin Coolers
  • Fin fan Cooler
  • ACC
  • Coil Cooler
  • Air Cooler
  • Dry Cooling Tower
  • Fin heat exchanger

What is the ACC fan?

It is a short form of air-cooled condenser fans.


What is the material of acc fan in power plants?

Mostly the material of ACC fan in the power plant is fibre reinforced plastic (FRP). Some small fans use different plastic grade, even some of the OEM is still using old metallic blades.


Why ACC Fan Company is different than ACC manufacturer?

The fan is a critical part of the equipment. It needs different expertise, Thus most of the OEM prefer to buy it from an expert acc fan company.


How much power in FRP Fin fan cooler fan can be saved?

We are sure about saving at least 20% power saving over any existing fin fan cooler fans. And in many cases, we have achieved even 35% power saving.

 

 

 

Mining ventilation fans

Type of mining in which Maya fan having its installation?

Following are the few major categories

  • Coal mine ventilation fans.
  • Manganese mine ventilation fans.
  • Gold Mine ventilation fans.
  • Fan for Uranium Mine.
  • Fan for Copper mine.
  • Underground iron mining fans.

These are not the only list we have the solution for any king of mine exists in mankind.


Which is a better axial fan or centrifugal fan in mining?

Airfoil axial fan is having maximum efficiency in fan industries and following are the brief difference between axial and centrifugal fans –

  • The axial fan is superior to deliver high airflow.

  • It required less power for similar operations compare to the radial fan.

  • It is compact in construction.

  • It is lightweight and simple in construction.

  • An axial fan is less expensive.

we can conclude axial fan is a better choice for mining ventilation.


Underground coal mine ventilation fans type and selection !

In underground coal mining, various hazardous gases emit and many of them are explosive and it is been derived from many mining accidents that high energy impacts of aluminum on rusty steel can cause a spark. Therefore aluminum bladed fans are banned in underground coal mining.

Coal mine ventilation use all three type of fan Main/Surface fan, Auxiliary ventilation, and booster fan.

So while selecting any of coal mine ventilation fans it should be taken care that underground fan should not have aluminum blade whereas for a surface fan it can be used.


What is the alternative of the aluminum blade in underground coal mining?

In general, steel is considered the only replacement for underground mining ventilation fans blade and by this either we need to compromise with less efficient propeller type fan or need to pay a high cost for CNC machined steel blade.

So at Maya, we have developed a series of auxiliary and booster fan in anti-static fiber which offers excellent efficiency and competitive in cost.


What is the parameter required to inquire for customized mining fans?

Following are the various parameter requirement for customized mining fan solution –

  • The requirement of airflow.
  • System pressure / Static pressure.
  • Air density.
  • Operating temperature.
  • Diameter restriction if any !
  • Installation Type (Forced draft or the induced draft)
  • Reverse rotation requirement.
