The process fluid is
circulated through the coil of closed circuit cooler. Heat from the
process is dissipated through the coil tubes to the water cascading
over the tubes exchanger. Simultaneously, air is forced upward, over
the coil opposite the water flow by the fans (axial or centrifugal). A
portion of the water is evaporated which removes the heat. The warm
moist air is discharged to the atmosphere while the cooled water drains
to the basin at the bottom of the cooler where it is recirculated by
the electrical pump up through the distribution system of the water
from more nozzles, and back down over the coils.
Typical applications:
- Air compressor cooling, plastic extrusion machinery;
- Evaporative chilling, free cooling systems, with direct cooling of water during winter season;
- Refrigerating fluid condensation.
