Adiabatic products

Adiabatic products are air-cooled coolers or condensers with adiabatic pre-coolers. Before the fan draws the ambient air through the finned coil, the air is pre-cooled adiabatically when traversing an humidification pad. This evaporates the water in the air, thus boosting the cooling capacity.

Key benefits

  • low process temperatures
  • saves more than 80% on annual water compared to cooling towers
  • up to 40% increased capacity compared to dry cooling (air temperatures approaching wet bulb temperature)
  • reduced energy consumption
  • operational safety: no water recirculation, no stagnant water, no aerosol generation, no water carry-over.
