A cooling tower mainly utilizes underlying heat of vaporization (evaporation) to cool process water. The air is cooled slightly beside due to their temperature increase. The selection and performance of the cooling tower are based on the water flow rate, the water inlet temperature, the water outlet temperature and the ambient temperature of the wet bulb. The ambient temperature of the wet bulb will have a direct effect on the cooling tower’s performance. The inside of cooling tower cisterns is susceptible to rusting, tarnishing, and dripping. Epoxy coverings on cooling tower linings can be fitted to seal and stop all seepages and safeguard the inner surface of the cooling tower.

How to measure the cooling tower performance?

The appropriate temperature of the wet bulb is identified by an instrument called a psychrometer. A psychrometer lays a small layer of water on the tube of a thermometer that spins in the air. After a minute, the thermostat displays a condensing temperature. The all-time low point, if no additional instability decreases the heat, is known as the wet temperature.

The identified wet bulb temperature is a combination of the relative humidity and the right temperature. The temperature of the wet bulb determines the amount of water vapour the atmosphere can intake under existing weather environments. As the temperature difference and the level of water flow are kept continual in the cooling tower, the Cooling capacity tends to be the same for both fully loaded and partly loaded.

Inevitable issues such as chemical compounds, lime or calcium accumulation, exposure to sunlight and the atmospheric conditions, and time of implementation will turn the cooling tower pieces of machinery to get worse, which can lead to heat flow structure failure. The inefficiency of the cooling tower may be due to several reasons.

  • Because of the scale accumulation on the tower heat interchange shells.
  • The decrease in airflow across the heat interchanges shells.
  • Inadequate water flow.

How to improve the cooling tower performance?

  • Through the Addition tower cell volume.
  • Check for the productivity damages as specified above.
  • Swapping the heat interchange shells with fresh, clean fill.
  • Verifying the air flow.
  • Fine-tune the flow of water.

Application of coating to improve the efficiency of cooling tower:

Applying an epoxy covering can improve flow capacity and preserve the tower cleanser for extended periods, decreasing the possibility of heat interchanger failure and prolonging the lifespan of the cooling tower. The ideal service providers must provide the following services:

  1. Use a tested process; with skilled technicians, you must perform adequate clean-up of the metal exteriors. Clean of the surfaces enabling additional absorption of the moisture.
  2. Apply appropriate levels of coating.
  3. The layer must be robust and should be intended for scrape resistance as well.
  4. The coating must have the strength to elongation and must be designed for surfaces of dense vibration or extension and shrinkage.
  5. Intended to resist cooling tower water management processes.
  6. Capable of tolerating high or low pH and salt levels
  7. Must not be pretentious to chemicals such as chlorine, and lead.
  8. Coating repair is unavoidable, whether during installation, shipping, functioning, or repairs. If the coating layers are ruptured in any way, because of damage, corrosion, blemishes, or water absorption, the safety must be provided.

To safeguard the cooling tower surfaces and improve the efficiency of cooling towers, contact the appropriate service providers immediately.
