DXH Series Hydraulic Motor Air Cooler

The explosion-proof air cooler fan adopts explosion-proof motor, explosion-proof marks: ExdⅠMb（YB3/YBK3）, ExdⅡBT4Gb,ExdⅡCT4Gb，Extdb21Db， rated voltage: AC380/440/660V, high strength, optimized structure, small windshield area,minimize the wind resistance pressure and noise of the air outlet ensure sufficient heat exchange. The heat exchange area per unit volume of the radiator core is large, and the heat exchange effect is high. The core body and fan with high heat exchange efficiency are designed to be compact in structure, easy to install and maintain.

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.
