  • Winter operation consideration for open cooling towers

    Open cooling towers are susceptible to freezing due to their inherent nature of operation, heat rejection by evaporation. As a result, ice formation becomes a subject of management, not elimination. Several design considerations should be made to minimize the time and effort spent on ice management. Take a look at our latest e-flash, winter operation consideration for open cooling towers that ...

  • Delta-T increased at biopharmaceutical manufacturing facility case study

    The cooling towers at a biopharmaceutical manufacturing company in the Midwest had become packed with scale. The severe scaling resulted in the inability of the towers to maintain any cooling capacity during extremely hot summer temperatures. RYDLYME approach 660 gallons circulated for 6 hours. RYDLYME results Cleaning resulted in Delta-T increase of 14°F! The gains in efficiency ...

  • Athlone Cooling Towers Demolition, Cape Town, South Africa Case Study

    The Athlone Cooling Towers in Cape Town, South Africa, were condemned due to structural damage caused by the heavy Cape winds. A decision was taken to demolish the Cooling Towers, despite the technical challenges and potential risk to nearby populations that this posed. In 2011, Knight Piesold was appointed as project manager to assist with the demolition of the Athlone Cooling Towers, by the ...

  • 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, resulting in ...

  • Enumeration of Legionella pneumophila in cooling tower water systems

    Legionella pneumophila, the causative agent of Legionnaires disease, is known to colonise and frequently grow in cooling tower waters. Disease is acquired by inhaling aerosol contaminated by legionellae. Determination of the count of Legionella pneumophila in cooling tower waters may, therefore, be useful for risk assessment. In our survey, 103 water samples from 50 cooling towers were examined ...
