Cleaning Cooling Towers: What You Should Know
|
|
Primarily used to cool water in air conditioning systems, cooling towers are also used to cool materials in process industries. Most of the newest cooling towers are made up of a pump, spray nozzles, fan, fill and a basin. Other components also include float valves, strainers and filters. Several people overlook the significance of a cooling tower to the overall energy efficiency of a cooling system in a building. Cooling towers are excellent air scrubbers. They concentrate dust, dirt, pollutants, insects, pollen and other contaminants during routine operation. Since these contaminants contribute to the development of microorganisms that represent health risks to maintenance personnel and the general public, cleaning cooling towers is necessary in order for the debris that builds up in the tower basin, fill and louvers to be removed, this is why we recommend using power washers. |

For pressure washer contractors, cleaning cooling towers is an unproblematic new market to explore since it has to be done at least once or twice a year. It is not usual for cooling towers in some parts of the country to be cleaned four times a year. In the commercial market, contractors probably have clients who own cooling towers. So, think of the potential extra earnings that one may have by adding a service such as cleaning cooling towers. Customary cleaning methods require that the cooling tower be taken offline and shut down by doing proper lock-out and tag-out methods. Power washers are commonly used for cleaning cooling towers' superstructure, basin and fill as they are very useful in removing scale build up on the basin and fill material. It is important to remove scale to prevent under-deposit corrosion and to improve the unit's heat transfer, making it run efficiently. In general, a pressure washer with 1500 psi of cleaning power or less is enough for acceptable cleaning performance without harming the fill material. |

A usual task in cleaning cooling towers may begin with cleaning the fill and superstructure first. Next is draining the system and emptying the basin. Too often, a huge quantity of debris may have been collected in the basin and this is usually cleaned using shovels. Once the debris has been removed, the pressure washer can then be used in cleaning the basin. With the advancements in pressure washer technology, newer machines are getting into the arena, allowing the tower to be cleaned even if it is online. For safety purposes, however, it is still good to shut off the electrical systems. Keeping the cooling tower online not just saves time, but also treatment chemicals and water.
