Working Principle
When the NWFL-VA adiabatic cooler operates:
The process begins as cold water gracefully cascades from the top of the cooler, evenly distributing itself across the high-efficiency evaporative cooling pads. Simultaneously, cool, dry air is expertly drawn in by the advanced EC axial fan, sweeping over the pads for an initial precooling phase. This adiabatic precooling of air significantly enhances its cooling capacity, making it even more effective at rapidly reducing temperatures of the warm process fluid. Such innovation ensures optimal performance and energy efficiency for all your multi-cell cooling applications.
