The OK-ELC air cooler series is designed specifically for hydraulic applications where high performance and efficiency is required and physical size must be minimized to allow easy installation.

  • Compact, efficient, high performance
  • Cooling capacity up to 28kW
  • AC motors with 230/400V, 50/60 Hz


  • Integrated pressure bypass valve (IBP) / Integrated thermal pressure bypass valve (IBT)
    The bypass channel is integrated in the cooling element. If a particular pressure is exceeded, the IBP opens the bypass channel, thereby protecting the cooling element from too high a pressure.
    Furthermore, the IBT only opens the cooling element path once a particular temperature has been reached.
