Side Stream Filter

Advanced Filtration Solutions for Efficient Water Treatment Systems

SF Cooling Towers Side Stream Filters are designed to maintain cleaner circulating water, improve cooling system efficiency, and help extend the service life of industrial equipment by continuously removing suspended solids, dirt, and other impurities.

Suitable for cooling towers, HVAC systems, process industries, and industrial water treatment applications, these filtration systems help reduce the risk of scaling and fouling, improve water quality, and minimize maintenance requirements.

Key Features & Advantages

  • Continuous removal of suspended solids, debris, and contaminants
  • Enhanced cooling tower and heat exchanger performance
  • Minimized scaling, fouling, and biological buildup
  • Extended equipment service life and improved reliability
  • Reduced maintenance, cleaning, and downtime
  • Optimized water consumption and chemical usage
  • Energy-efficient filtration for consistent system performance
  • Automatic and manual backwash options for operational flexibility



  • The system works by diverting a controlled portion of circulating water through a filtration unit, where suspended particles and impurities are removed before the filtered water is returned to the system. This continuous filtration process helps maintain better water circulation, supports efficient cooling system operation, and contributes to long-term equipment performance. The lower exit-air velocity of Forced Draught Cooling Towers can help reduce water carryover, while properly designed drift eliminators further limit drift and support cleaner, more controlled operation.

    Their compact footprint makes them suitable for industrial applications where available installation space is limited. Maintenance can also be more convenient because the fan and drive arrangement is positioned near ground level, while removable sections can provide easier access for internal inspection and servicing.

    Forced Draught Cooling Towers are generally well suited to small and medium-capacity industrial cooling applications, particularly where compact installation and accessible maintenance are important. For larger and more demanding cooling requirements, Induced Draught Cooling Towers may be considered depending on airflow requirements, operating conditions, available space, and overall system design.
