Refrion® WET Adiabatic Coolers
Accessories for dry coolers
Adiabatic systems are standard products or accessories for some Liquid Coolers able to increase the relative humidity of the air passing through the exchanger, so as to decrease the temperature and increase heat exchange. This happens through the physical principle of the latent evaporation heat in which the water, by evaporating, absorbs heat from the air entering the heat exchanger, lowering its temperature.

How They Work
The adiabatic saturation reduces the suction air temperature (respect to the ambient air) and therefore the efficiency of the heat exchanger increases. The adiabatic saturation temperature
lowers – since evaporating water removes heat – though it is still higher than the dew temperature, as evaporation itself raises the partial pressure of water vapour. Thanks to LUVE's systems, the adiabatic saturation guarantees an increase of the relative humidity up to the whole saturation of the air (R.H.=100%)
LUVE has developed 3 different adiabatic systems, to guarantee maximum system efficiency for different environmental conditions and a single control system for their management
HYBRYD SPRAY SYSTEM (H.S.S.)
Water atomisation system available for the liquid coolers and the air cooled condensers.
SPRAY ADIABATIC
SYSTEM
Inlet air humidification through water atomisation.
INDUSTRIAL ADIABATIC SYSTEM
(PADS)
Inlet air humidification by means of special adiabatic panels.
In choosing the most appropriate LUVE WET adiabatic system for the installation needs, it’s necessary to consider the following parameters:
- Estimated annual operating hours
- Percentage of increase in relative humidity obtainable
- Percentage of saturation obtainable
- Maximum reduction of the obtainable air temperature.
The choice also leads to different consequences in terms of initial investment, subsequent operating management costs, savings in terms of electricity and water used, duration (see table below).
LUVE guides you to the selection through the software calculation Web Selector for selecting the most suitable products and systems for your needs. In addition LUVE provides you a consultant from the technical office to support you to find the ideal solution for your next installation.
