Dry or air cooled products

Dry or air-cooled products cool liquids or condensate gases in closed circuits via sensible heat transfer from high-density finned coil to air at ambient dry bulb temperature.

Key benefits

  • Eliminates water usage and treatment
  • Eliminates plumes
  • Reduced maintenance
  • Eliminates Legionella risks

Why go for evaporative rather than dry cooling?

  • When you need a fluid outlet temperature close to the design ambient dry bulb temperature
  • To save on energy costs
  • If the cooling unit plan area is compact or restricted

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.
