  • Biofilm effect on Cooling Towers for industrial purpose - Case Study

    Cooling towers are used widely in the industry for cooling down a process, there exist many version or types of cooling towers, and each designed with its advantages for the process. The generic term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. While most think of a "cooling tower" as an open direct contact heat rejection ...

  • The Applications of an Industrial Drying Oven

    Industrial drying ovens are designed to simultaneously heat a material while withdrawing moisture from its surface, a process with many commercial, pharmaceutical, and industrial applications. These are primarily used for batch processes – though varying product or research requirements need vastly different mechanisms and components. However, there is a basic three-stage operating process ...

  • Closed Circuit Coolers: Design with winter in mind

    When outside temperatures fall below freezing, water inevitably forms into ice. Open cooling towers can be susceptible to freezing due to their inherent nature of operation. As a result, ice formation becomes a subject of management, not elimination. Fortunately, there are alternative solutions. Closed circuit coolers are used for a multitude of niche applications, but are ideal for evaporative ...

  • New York Legionella regulations: are they missing the boat?

    Abstract A large outbreak of Legionnaires’ disease in the Bronx in 2015 prompted NYC to enact law and NYS to propose emergency regulations on the registration and maintenance of cooling towers. This paper describes the fundamental characteristics of point sourced vs. potable water sourced outbreaks and discusses the Bronx outbreak from those perspectives. Ultimately a case is made that ...

  • 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, ...
