Optimal heat transfer properties – low pressure drop; Generally, every cross fluted fill could be cut to be installed in a cross-flow cooling tower. Such a fill, however, would not perfectly fit the requirements; we therefore developed a special range of fill for this type of tower (FX12.12 or KSN with a drift eliminator section KSA and air inlet louvre section KSB).

  • Optimal heat transfer properties
  • Low pressure drop
  • Fills especially designed for cross-flow cooling towers
  • Fills with integrated inlet louvre and drift eliminator section
  • Easy installation
  • Long service life due to chemical, bacterial and UV resistance of PP and PVC

Installation depths (air travel distance) and inclination vary with each brand of cooling tower. We offer fill depths of 300 and 600 mm. Combinations of these allow different installation depths (e.g. 300 + 600 = 900 mm). In most crossflow cooling towers the fills are vertically installed at a certain angle (e.g. 10°). Our cross-flow cooling tower fills are cut to the required angle of inclination upon customer request.

Blocks with the integral drift eliminators (2H KSA) must be installed at the air outlet side (inside of the tower). The straight channels are directed upwards in the direction of flow. Our fills have been shown to meet all drift eliminator requirements at air speeds between 1 and approx. 3.5 m/s. To avoid any risk when operating above this air speed, it is suggested an extra drift eliminator be installed at a distance of 300 mm behind the 2H KSA fill. The best type for this purpose is the 2H TEP 130 drift eliminator. Blocks with the integral air inlet louvre (2H KSB) must be installed at the air inlet side of the tower. The straight channels are directed downwards in the direction of flow. Depending on installation depth in the cooling tower, a 2H KSN type fill can be installed between 2H KSA and 2H KSB fill (see sketch). Due to its corrugation geometry the 2H FX12.12 could be installed vertically without inclination. At air velocities higher than 3.2 m/s a small inclination of 2° is required.

We offer water distribution nozzles for cooling towers, humidifiers, scrubbers, air coolers and aerators. These nozzles are made of glass fiber reinforced polyamide (nylon). Being correctly assembled, the axial nozzles distribute the water with a spray angle of 120°, providing optimum water distribution above the cooling tower packing.

  • Axial nozzle designed as complete cone spiral nozzle which consists of a casing and an insert.
  • After correct assembly the nozzle distributes the water with a spray angle of 120°.
  • The water flow rate depends on the operational pressure.
  • The arrangement in the plant, i.e. nozzle distance and height, is dependent on the respective plant design.

Advantages of the SPN Nozzles:

  • Optimum water distribution
    Full cone nozzle with maximum spray angle of 120°
  • Low clogging and scaling tendency
    Due to smooth surface design
  • Constant self-cleaning
    By high turbulence in the nozzle body
  • Easy installation onto the piping system
    Due to BSP thread and hexagon body design
  • High resistance to a large range of chemicals
    Nozzles are made of glass reinforced polyamide (nylon)
