Disposal of heat into the atmosphere may seem like a waste of a precious good. But what to do with the heat that cannot be used for other purposes? Probably the temperature level is too low or there is simply no way to use it.

In any case, a recooling system is necessary. There is a wide range of different technologies available: Dry coolers, adiabatic coolers, hybrid coolers, open or closed cooling towers.
The different technologies are not easy to compare, because they influence the basic process.
Until today energy efficiency for a chiller is mainly given for a dry condenser or dry cooler. Wet cooling can lower the condensing or glycol temperature significantly, and by that energy efficiency of the whole process rises.
