When the ambient air is below the set point, the unit runs as a dry cooler to save water and energy. The ambient air condenses the refrigerant in the microchannel coils which is then returned to the system.
When the ambient temperature is above the set point, the unit will run in On-Demand Adiabatic™ Pre-Cooler mode. Water is evenly sprayed over the highly efficient On-Demand Adiabatic™ Pre-Cooler media. As the air passes through the media, water is evaporated in to the air, and the air is humidified, cooling temperatures down to 2-3ºF above wet-bulb temperature. Such substantial depression of the dry bulb temperature results in a major increase in dry cooling capacity.
The cooler air passes over the microchannel and condenses the refrigerant in the microchannel which is then returned to the system. In the sump there is an industrial duty pump that recirculates the water. Part of the distributed water is evaporated, while the excess water assists in rinsing the On-Demand Adiabatic™ Pre-Cooler media to keep it free from debris and minerals that would otherwise stay behind on the media after evaporation. The EcoFlex Controls determine when the water is purged from the sump.
The TrilliumSeries™ Condenser is furnished standard with state of the art EcoFlex controls that provide efficient year round performance. Each unit is shipped with custom controls logic that reduces energy consumption and optimizes water usage. With preset controls, the system is programmed and ready to operate upon arrival from the factory.
