AIR-OIL HEAT EXCHANGERS WITH ALTERNATING CURRENT ELECTRIC FANS - SERIE AP:
Today the use of air in hydraulic equipment is more and more common.
The benefits are: No water supply required Totally independent of plummed systems Reduced running costs in comparison with the water-oil exchangers, even if initial investment is higher
Residual warm air can be used for heating
With air-oil heat exchangers the radiator unit is of aluminium for minimum conduction.

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.

When the external temperature is lower than the internal
temperature and a “maintenance free ” system is requested, a
X-LINE air to air heat exchanger is the most convenient choice.
The air to air heat exchanger XVA, with the internal patented
aluminium core, satisfy completely the market request by small
dimensions, very high efficiency and new design.
Four sizes from 16 W/K to 85 W/K heat transmission rate.
They are always supplied with deflectors for the outlet of ambient and enclosure air in order to optimize the enclosure thermal management.

AAF has long recognized the need for a new type of gas cooling device, one that not only cools process gases, but one that could be designed to recover the heat to be used in other processes. It was with these objectives that AAF developed the Forced Air Cooler (FAC), or air to air heat exchanger, and now has over 50 of them installed worldwide, either operating or under construction. The FAC can be used for cooling kiln or preheater gas and clinker cooler gas. It has several advantages over conventional methods of cooling by U-tube coolers, water spray towers, and cooling by dilution air. The FAC is compact and can be fitted into spaces where a U-tube cooler will not. It can be designed to maintain a constant outlet temperature, independent of the ambient air temperature. It cools the gas without adding to the volume, unlike dilution cooling and water spray cooling. The tube bundle section can be shipped in one piece, thereby reducing field installation costs. A thermocouple mounted in the FAC outlet duct controls the fans as required to maintain a constant outlet temperature. Several different duct arrangements are available, including top entry, bottom entry, and side entry.

Coolers reduce the temperature of the hot gases in the installations.
Thus they allow the reduction of the quantity of dust-laden gas to be treated and therefore the minimisation of the size of the dust extractors installed downstream.

Product description
With this new generation of Universal Hydraulik LKI oil-coolers, the manufacturers have succeeded in reducing the noise level. These coolers are ideally suited for stationary installations - for the cooling of hydraulic or lubricating oils. The range has been extended to include slow-running ventilators, and the housings have been optimised, in order to produce the very low noise level. In order to make the cooler range as comprehensive as possible, the smaller models are also available as single or dual versions, thus covering oil-cooling requirements for both low and high oil throughflow volumes.
