Working Principle
When the NWFL-VA adiabatic cooler springs into action:
Refreshingly cold water cascades elegantly from the apex of the cooler, smoothly permeating the high-efficiency evaporative cooling pads. Meanwhile, cool and dry air is ingeniously drawn in by the state-of-the-art EC axial fan, gliding over the pads and undergoing precooling. This innovative adiabatic precooling of air amplifies the cooling capability, delivering exceptional refrigeration for efficiently chilling the warm process fluid.
