When the ambient air temperature is below the set point, the unit operates as an air cooled condenser.
Ambient air (1) is drawn over the dry finned coils (2) by axial fans (3) and condenses the refrigerant (4).
On-Demand Adiabatic Pre-Cooler Mode
When the unit is in On-Demand Adiabatic Pre-Cooler mode , water is evenly sprayed over the highly efficient pads (5) located in front of the dry finned coils (2). At the same time axial fans (3) draw ambient air (1) through the pads. A portion of the water evaporates and cools down the air from the dry-bulb temperature close to the wet bulb temperature (typically 8 to 10°C lower). This increases the cooling capacity significantly. The cooler air passes over the coils and extracts the heat from the refrigerant.The excess water assists in rinsing the pads and is recirculated by a pump (6). The EcoFlex Controls regularly purge the water from the sump.
