Trouble Shooting For Cooling Towers

TROUBLE SHOOTING FOR COOLING TOWERS 

#	Problem / Difficulty	Possible Causes	Remedies/Rectifying Action
1.	Excessive absorbed current / electrical load	1. Voltage Reduction	Check the voltage
		2 a. Incorrect angle of axial fan blades	Adjust the blade angle
		2 b. Loose belts on centrifugal fans  (or speed reducers)	Check belt tightness
		3. Overloading owing to excessive air flow-fill has minimum water loading per m2 of tower section	Regulate the water flow by means of the valve
		4. Low ambient air temperature	The motor is cooled proportionately and hence delivers more than name plate power.
2.	Drift/carry-over of water outside the unit	1. Uneven operation of spray nozzles	Adjust the nozzle orientation and eliminate any dirt
		2. Blockage of the fill pack	Eliminate any dirt in the top of the fill
		3. Defective or displaced droplet eliminator	Replace or realign the eliminators
		4. Excessive circulating water flow  (possibly owing to too high pumping head)	Adjust the water flow-rate by means of the regulating valves. Check for absence of damage to the fill
3.	Loss of water from	1. Float-valve not at correct level basins/pans	Adjust the make-up valve
		2. Lack of equalizing connections	Equalise the basins of towers operating in parallel
4.	Lack of cooling and hence increase in temperatures owing to increased temperature range	1. Water flow below the design valve	Regulated the flow by means of the valves
		2. Irregular airflow or lack of air	Check the direction of rotation of the fans and/or belt tension (broken belt possible)
		3a. Recycling of humid discharge air	Check the air descent velocity
		3b. Intake of hot air from other sources	Install deflectors
		4a. Blocked spray nozzles (or even blocked spray tubes)	Clean the nozzles and/or the tubes
		5. Scaling of the fill pack	Clean or replace the material (washing with inhibited aqueous sulphuric acid is possible but long, complex and expensive)

Savings on New Cooling Tower

As we are the leading manufacturer of Cooling Tower in central part of India. We observe few points that can be beneficial for any organization to make savings on Cooling Tower.

Cooling towers as prefabricated, have not been the choice in past. Now a days era, replacing an old cooling tower can offer various options that might have been neglected in past.

• The savings on labor, over a 'field' erected unit is not new. However, the latest advancements in technology have helped level the ‘field’. New technology offered some advantages as less lead time and build time.

• Latest designed cross flow cooling towers and advanced drift eliminators improves efficiency that plays a vital role. 

• Materials used to build a cooling tower ensures the compact design and low weight units. Materials as Composites Reinforced Fiberglass (FRP) can be used to achieve it.

• Cooling tower basins can also play a crucial part on construction type. Most of the time on-site construction requires a concrete basin as a foundation, while most factory assembled units have a self-contained basin.

• Some new designs are also available without basin, however, that allow existing basin to be used when updating to a newer factory assembled cooling tower systems, thus results in additional savings.

• Multiple cells can also be mounted even be mounted on an existing basin.
