An air cooler can be installed easily and virtually anywhere. Operating costs are therefore low and can be further reduced by using a speed-controlled fan. Coolers equipped with special, low-noise fans and optimised air ducting facilitate the provision of particularly quiet coolers.<br />The broad product range of coolers with axial and radial fans, three-phase AC, DC and hydraulic motors enables flexible adaptation to a multitude of applications and ambient conditions.

They are supplied by a fixed displacement pump and can be installed directly next to the fan motor, by the cooler or somewhere else.<br /> Optionally, these controls can also be delivered with reversal, to “blow out” the cooler from outside to free it from dirt (e.g. dust and sand).</p></div><div><p><strong>Field of application</strong></p><p>For transmission cooling and for hydraulic systems in all mobile working equipment and vehicles, such as</p><ul><li> Mobile cranes</li><li> Concrete mixers and pump drives in concrete vehicles</li><li> Road surfacing machines</li><li> Construction machines (excavators, wheel loaders)</li><li> Agricultural machines</li><li> Municipal machines</li></ul></div>

Air cooling is a convenient method of dissipating heat loss from industrial and mobile systems.<br />The medium to be cooled – usually oil or a water-glycol mixture – flows through a heat exchanger. A fan draws in ambient air and feeds it through the cooling element. The difference in temperature causes a heat exchange to take place, whereby the cooler air absorbs the heat from the medium and releases it back into the atmosphere.<br />This allows the medium to be cooled down to a few degrees Celsius above ambient temperature.<br />At HYDAC you will find the right air cooling unit to suit your needs, from standard to large coolers for use in the energy sector or even custom-made coolers for mobile machinery.
