Evaporative coolers differ from evaporative towers in that they use a heat exchange coil for the primary process fluid.
WHAT DOES THIS MEAN?
Having a machine with the process fluid inside a heat exchange coil allows the primary fluid not to be “dirtied” by sediments or microparticles present in the water. The presence of the heat exchange coil also makes it possible to use glycolised process water where the system requires it.
Key points for choosing an evaporative cooler instead of an evaporative tower:
