Fills for Cross-Flow Cooling Towers

• 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

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; therefore GEA 2H Water Technologies GmbH 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).

Installation depths (air travel distance) and inclination vary with each brand of cooling tower. GEA 2H offers fill depths of 300 and 600 mm. Combinations of these allow different installation depths (e.g. 300 + 600 = 900 mm). In most cross-flow cooling towers the fills are vertically installed at a certain angle (e.g. 10°). The GEA 2H cross-flow cooling tower fills are cut to the required angle of inclination upon customer request.

Blocks with the integral drift eliminators (KSA) must be installed at the air outlet side (inside of the tower). The straight channels are directed upwards in the direction of flow. GEA 2H 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 KSA fill. The best type for this purpose is the TEP 130 drift eliminator. Blocks with the integral air inlet louvre (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 KSN type fill can be installed between KSA and KSB fill (see sketch). Due to its corrugation geometry the FX12.12 could be installed vertically without inclination. At air velocities higher than 3.2 m/s a small inclination of 2° is required.
