Most installations are sized according to maximum temperatures occurring only rarely during the year, this being exacerbated by the heat-wave phenomenon of recent years, implying over-sizing and therefore a larger footprint, higher sound levels and greater investment in terms of non-productive exchange surfaces.
Adiabatic air coolers provide a response to this type of climatic constraint:
in effect, this system retains the advantages of a dry air cooler, that is where the process circuit is closed, retaining the quality of process fluids without atmospheric pollution or the development of bacteria.
This process, exclusive to GEA, enables the air inflow to be charged with water and therefore its temperature lowered. Mains water is sprayed through nozzles mounted on booms, the position and angle of dispersion of which have been designed so as to charge the air with water efficiently and make maintenance easier.
Water consumption remains limited because spraying only operates at the hottest times of the year thanks to a system of regulation.
Since adiabatic air coolers do not have a tank to collect the water and no water treatment is required, they comply with current legislation concerning protection against legionella bacteria and other proliferations.
This concept avoids the over-sizing of air coolers, and therefore reduces the dimensions of the exchanger, reduces the amount of power used by the fans, as well as the sound level of the installation.

The air cooler cools the water or oil using external air by means of a single-piece exchanger with continuous tubes and fins and fans. These fans can either be arranged above the equipment, in “induced draught” mode (RGR-TGR range), or below the equipment in “forced draught” mode (RGF-TGF range). The arrangement depends on the thermal characteristics of the installation established at the design stage.
This range of pre-specified air coolers enables us to be very proactive when it comes to delivery deadlines and to offer ...
