Dry and adiabatic cooling

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.
