Two-Stage Adiabatic Cooling
The two-stage adiabatic cooling combines both indirect evaporative cooling and direct adiabatic cooling within a single unit. In the first stage, cold circulating water is produced through evaporation and used to pre-cool the air in an air-water heat exchanger. In the second stage, the air is then further cooled using wet evaporative media.
As no moisture is added to the system in the first stage, the result is significantly cooler and drier air. Therefore, with two-stage adiabatic cooling, even higher efficiency, more optimal hall climate conditions, and reduced water consumption are achieved.
With the two-stage cooling process, the supplied air temperature reaches 19°C under conditions of 35°C and 30% RH (EuroVent), while under warmer, drier conditions (38°C, 20% RH), it can even drop to as low as 17°C.
