Field Erected Cooling Towers

IWC’s comprehensive range of field erected cooling towers includes Concrete Field Erected Cooling Towers, Pultruded GRP Field Erected Cooling Towers, and the Tektower EWB range of Field Assembled Cooling Towers.

Cooling Towers are heat rejection devices used for cooling water – or other working medium – to near the ambient wet-bulb air temperature. Cooling towers use evaporation of water to reject heat from processes such as cooling the circulating water used in oil refineries, chemical plants, power plants, steel mills and food processing plants.

An industrial water cooling tower extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. Towers that use this process are called evaporative cooling towers.

The process is termed “evaporative” in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. The heat from the water stream transferred to the air stream raises the air’s temperature and its relative humidity to 100%, and this air is discharged to the atmosphere.

Evaporative heat rejection devices such as industrial cooling systems are commonly used to provide significantly lower water temperatures than achievable with “air-cooled” or “dry” heat rejection devices, like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in need of cooling.

Think of the times you’ve seen something hot be rapidly cooled by putting water on it, which evaporates, cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one.

The industrial water cooling towers vary in size from small roof-top units to very large hyperboloid (hyperbolic) structures that can be up to 200 metres tall and 100 metres in diameter, or rectangular structures that can be over 15 meters tall and 40 meters long. Smaller towers (package or modular) are normally factory-built, while larger ones are typically constructed on site in various materials.

Concrete Field Erected Cooling Towers

Concrete Field Erected Cooling Towers

IWC are the leaders when it comes to designing and constructing large field-erected industrial cooling systems according to clients’ specific needs and operating conditions.

IWC offer various water cooling tower solutions ranging from counter flow to crossflow configurations in either forced or induced draught. These are available in numerous different materials of construction as follows:

  • Reinforced Concrete
  • Steel (Painted, Hot Dip Galvanized or Stainless Steel)
  • Wood
  • Pultruded fibre glass

Various types of fill can be used, which are dependent on the application and water quality. Some fills on offer are:

  • Film Packs – Clean water
  • Trickle Packs – Moderately dirty water
  • Splash Packs – Dirty water
  • Splash Bars – Very dirty water

Pultruded GRP Field Erected Cooling Towers

Pultruded GRP Field Erected Cooling Towers

IWC’s Pultruded GRP (glass reinforced plastic) Field Erected Cooling Towers offer the best solution for long term use in corrosive environments. GRP is a modern material that has many advantages over traditional construction materials such as concrete, steel, or wood.

Advantages include:

  • Exceptional chemical and corrosion resistance
  • Resistance to all types of “aggressive” water (for example sea water)
  • Resistance to weather conditions
  • High impact strength
  • Rigidity
  • Light weight

Tektower EWB Field Assembled Cooling Towers

Tektower EWB Field Assembled Cooling Towers

The Tektower EWB range of Field Assembled Cooling Towers comprises an easily expandable range of evaporative cooling towers produced from non-corroding components.

Tektower EWB Field Assembled Cooling Towers

Shipped in knock-down form the EWB range is suitable for project sites where large cooling capacities are required but where access may be restricted.
