Mobile series OK-ELH and AC-LNH

The coolers of the OK-ELH/AC-LNH series are equipped with a hydraulic motor and designed specifically for mobile applications where high performance and easy installation in confined spaces are required.

  • Cooling capacity up to 140 kW
  • Hydraulic motors from 6.3 to 22 cm³/rev
  • Simple dismantling of components
  • Hydraulic fan controls

    Hydraulic fan controls from HYDAC are at the hydraulic heart of the system. They control the speed of the fan depending on the temperature of the medium. They are supplied by a fixed displacement pump and can be installed directly on the fan motor, on the cooler or other location. As an option, these controls can also be supplied with a reversing function to "purge" the cooler of external dirt, dust and debris.

    Right from the design stage, these fan controls in mobile machines are always designed to be fuel efficient thus helping to reduce emissions and also to meet future environmental regulations efficiently.

    Typical applications

    For transmission cooling and hydraulic systems in all mobile machines and vehicles, such as

    • Mobile cranes
    • Concrete mixers and pump trucks
    • Construction machines
    • Agricultural machines
    • Municipal machines
