Cost & Benefit has to be calculated over the course of a year (and the life cycle of the tower) and is a simple comparison of:

  • Water Consumption m3 (ft3)
  • Power Consumption KW (Hp)
  • Water Treatment Expenses (chemicals, maintenance etc)


with this in mind we need to compare the different cooling options (open, closed, hybrid, adiabatic) to come up with a comparison between the systems based on: (follow us down the page to explore…)

If the past is any lesson, the rates will probably increase 3 – 6% annually…that also means that water / energy cost can double or quadruple within the life time of our towers… (15-20 plus years)

The one open factor in all of this is the raise of Water and Energy costs.
