DXH Series Hydraulic Motor Air Cooler
The cooler, through vacuum brazing process, is driving by two-way gear hydraulic motor and high-strength fan blades to achieve stable cooling effect.
High performance hydraulic motor can continuously keep running under complex working conditions.
· Temperature controller can be selected.
· A variety of pressure protection forms can be selected.
· The oil inlet and outlet of the cooler are standard G thread, also can be customized or connected with SAE flange as required.
· Equipped with hydraulic motor
· Suitable for mobile machinery at outdoors
· Suitable for pump truck
It is composed of hydraulic motor,high strength fan blades and tightly structured high efficiency fin.
With high performance hydraulic motor,it can operate for a long run-on period continuously under complex working conditions,and it can be maintained with low operation cost easily.

Note: * Cooling capacity: cooling power at △T=40℃. ** The noise value is measured at a distance of 1m from the cooler, which is only for reference. Because it is affected by the surrounding environment, medium viscosity and reflection. *** Displacement of hydraulic motor: It can be adjusted appropriately according to the requirements of working conditions. (If necessary, please contact DONGXU service team) Hydraulic Motor Flow [l/min] Q=Vg*n/1000/η . In Q,Vg=Displacement of hydraulic motor[ml/r]; N=Fan Speed [rpm]; η=Volumetric Efficiency of Hydraulic Motor 90%,(Working pressure is 150bar) ****DXH series can apply in occasion of explosion proof and requiring corrosion protection in harsh environment.
