  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...

  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...

  • How to Increase Your Industrial Cooling Tower Efficiency

    Although cooling towers are generally some of the most cost-effective cooling mechanisms as compared to other cooling technologies (such as many dry air cooling systems), it is still important to monitor your industrial cooling tower efficiency and run it as seamlessly as possible. This will ensure your facility can: Save energy Reduce the amount of ...

  • Biofilms reduce cooling tower efficiency, increase cost, and create a biohazard

    Definition: Biofilm is a gelatinous layer that forms in cooling water systems on heat transfer surfaces, fill material, and basins. Biofilm consists of microbial cells, the polysaccharide biopolymer they produce, and debris extracted from the recirculating cooling water. Problems Caused by Biofilm: Physical plugging of cooling tower fill, tubes, and water passages Accelerated ...

  • Novel methodology for evaluating economic feasibility of low-water cooling technology retrofits at power plants

    Increasing demand on water supplies – already strained by population and economic growth and instream flow requirements – means many areas are considering conservation and reallocation to meet their needs. One method of increasing water availability is through low-water cooling technologies at thermoelectric power plants. Cooling towers, hybrid wet–dry and dry cooling ...

  • Ozone systems for beginners

    This paper is intended for people who know a cooling tower when they see one but have little or no knowledge of their care or what part ozone plays. I have tried to make this as simple as possible and there is even a block diagram on the last page to help you out. Ready? Okay, here is what you need to know first: The sole function of ozone use in evaporative cooling towers is to disinfect water. ...
