Cooling Tower Parts

Our offered Product range includes Film Fills for Cooling Towers, Cellular Drift eliminators, Double Wall Drift Eliminators and Perforated V-Bar.

Film Fills For Cooling Towers

Film Fills are the most efficient filling media available for cooling towers. The usage of film fills in both counterflow and crossflow cooling towers allows relatively smaller sized towers to cool an equivalent amount of water compared to cooling towers using splash fills. This results in the saving of not only capital costs for a new tower but also reduces operational costs on account of lower height and hence lower pumping costs.

Film Fills work on the principle of offering heat exchange by spreading the falling water droplets into a thin molecular film where the air can effectively contact the entire surface of the water film to carry away heat and mass.

Advantages
    • Minimum resistance to air flow

    • Good distribution of water leads to turbulent mixing of air and water to maximize heat transfer.

    • Reduced fill height and greater cooling capacity results in lower power consumption.

    • Erosion and rotting resistant and long lasting (10-12 years of service time in good quality water)

    • Self-supporting, high strength and self-extinguishing characteristics

    • Resistance to weather exposure (fungii/oxidation) ; Nearly impervious to chemical degradation by Alkali, acid, grease, fats, oils and biological attack

  • Easy to glue at site, reduces transportation cost.

Cellular Drift Eliminators

  • Material Rigid PVC
  • Maximum Face Velocity 4.5 m/sec
  • Module Length Can be chosen in 600-mm increments.  Max suggested length – 1800-mm
  • Module Depth 130 / 146 mm
  • Pitch 20 mm
  • Maximum Spacing of Support with  standard thickness of sheets 800 mm
  • Directional changes for air flow 3
  • Standard Thickness (Corrugated/Plain) 0.3mm/0.4mm
  • Average Weight 7.6 / 8.5 kgs/m2
  • Expected Drift Loss < 0.001% / 0.0005% of circulating water
  • Maximum Continuous Temperature (deg Celsius) 55°C
Water droplets are separated from the air drift at the three direction change points on the drift eliminator. The CD-S130/146 drift eliminators provide a rugged cellular structure formed by the solvent bonding of sinusoidal shaped corrugated sheets. Individual S-shaped corrugated sheets are bonded with subsequent layers to create the structure. The entire area is thus divided into several smaller S-shaped mini zones.
Features and Advantages
  • The modules are provided additional strength by the insertion of stiffener sheets at regular intervals.
  • Cellular type drift eliminators offer the highest drift elimination efficiency while introducing a lower static pressure drop
  • The eliminators can be assembled as well as cut at the field installation to ensure tight fit.

Double Wall Drift Eliminators

  • Material Rigid PVC
  • Type Of Structure Double wall
  • Maximum Face Velocity 5.0 m/sec
  • Module Length Up to 3500 mm
  • Module Depth 146 mm
  • Pitch 56.5 mm / 66 mm
  • Recommended spacing between supports 2000 mm
  • Max Recommended Supporting Span 1830 mm
  • Directional changes for air flow 3
  • Average Weight 8.15 kg/m2 / 6.6 kgs/m2
  • Maximum Continuous Temperature (deg Celsius) < 0.002% / 0.05% of circulating water
  • Maximum Continuous Temperature (deg Celsius) 55°C
The double walled construction offers unmatched strength especially for installations where foot movement on drift eliminators is a given. They can be pressure washed, if necessary, without any damage.
Features and Advantages
  • The outgoing air is first guided on to the surface of the drift eliminators. This drift laden air then traverses the upward path of the drift eliminator. At the point of the first direction change DrifEl146 introduces a small water entrapment groove. A majority of water droplets are trapped at this notch and channel back into the system.
  • Unlike other drift eliminators, where large water entrapment areas lead to increase in pressure drop, the path to air velocity remains sinusoidal, thereby introducing little to no additional pressure drop at this point.
  • The air with the remaining drift droplets undergo another direction change and encounter the surface of the adjacent blade. The system continues to work on the principle of inertial separation. At the exit of the drift eliminator, the air undergoes a third direction change while the water droplets encounter a second notch, which entraps a majority of the drift droplets and brings them back into the system.

Perforated V-Bar

  • Material of Construction Rigid PVC
  • Overall Dimensions 62mm x 62mm
  • Length Length
  • Shape and Size of Perforations Diamond / Circular
  • Thickness at load points 1.2mm to 1.5mm
  • Colour Black / Grey
Perforated V-Bar is the most extensively used product in the industry. COOLDECK can supply the stainless steel or FRP coated wire mesh as well as the other components that are needed for the entire splash bar system.
The water droplets spread over the solid surface and perforated holes of the splash bar. The flowing water is held on the holes due to surface tension and forms a thin film. The water film formed over these rectangular holes has very low surface tension at its corners and thus a tendency to rupture frequently. During this process of rupturing the water film is broken into small globules, thus providing maximum heat transfer.
Features and Advantages
  • Diamond shaped perforations are recommended as they offer the ideal surface tension to rupture the water droplets.
  • The top edge of the V-bar is reinforced so as it offer bending and load strength.
  • Ensuring a minimum thickness of 1.5mm and a maximum distance of 600mm between adjacent bars will help reduce the possibilities of sagging.
  • Compact locking of the V-Bar on the grid using a V-Bar clip (as depicted in the picture) will also ensure a sturdy fill structure.
  • The overhang of the V-bar of the last grid should be restricted to 150mm.
  • Algae resistant and Fire retardant
COOLDECK's V-BAR clip design provides secure locking capabilities preventing wear on both the wire hanger and the fill. The tab locks provided on the V-bar prevent it from slipping once locked into place.
