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

  • Cooling capacity up to 34kW
  • DC motors with 12V or 24V
  • Compact, efficient, high-performance

ESC (Electronic Speed Control)

With electronic speed control (ESC) it is possible to control the fan speed smoothly, according to the oil temperature. This ensures that the fan speed is precisely coordinated to the required cooling capacity and the oil temperature remains constant.

As an option, these controls can also be supplied with a reversing function to "purge" the cooler of dirt, dust and debris.

Typical applications

  • Mobile cranes
  • Concrete pumps
  • Drilling plants
  • Roadwork machines
  • Construction machines
  • Agricultural machines
