  • Low recirculation rate evaporators

    Abstract Fin coil evaporators with enhanced internal tube surfaces allow for optimum performance with a minimal overfeed rate. Reducing the overfeed rate requiresless pumping power and smaller line sizes to the evaporator. Additionally, less compressor power is required for the same refrigeration capacity because the wet suction line pressure drop is reduced. Lower compressor power results ...

  • Hot weather on its way ... Check the condition of your cooling tower

    The approach of summer is a good time to check the performance and, more importantly, the physical condition of your cooling towers. After all, it’s easier to repair a tower when weather conditions don’t put a strain on its cooling capacity. A cooling tower passes air over tiny droplets or the exposed surface of a water film. In both cases, a small amount of water is vaporized, ...

  • 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,  ...

  • Republic Steel: CapDI for Cooling Towers - Case Study

    Introduction & process description Water is often a hidden cost of industrial sites and can contribute significantly to operational costs. Cooling towers are used to reject heat through the natural process of evaporation providing cooled water across a broad range of applications. Due to evaporative losses, the water remaining in the cooling tower becomes concentrated with dissolved ...

  • Fungal biodiversity and mycotoxigenic fungi in cooling-tower water systems in Istanbul, Turkey

    This is the first study to assess fungal diversity and mycotoxigenic fungi in open recirculating cooling-tower (CT) water systems (biofilm and water phase). The production capability of mycotoxin from fungal isolates was also examined. The mean fungal count in 21 different water and biofilm samples was determined as 234 CFU/100 mL and 4 CFU/cm2. A total of 32 species were identified by ...

  • 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 ...
