Oil-/ air cooler

HBE oil-/air coolers have been designed for a fast cooling in return lines of hydraulic systems. They are featuring an especially low-noise operation as well as a high cooling performance. The oil-/air coolers are available in different sizes.

Series LKI

With the new generation of LKI oil coolers, the noise level has been successfully reduced. These coolers are ideally suited for stationary installations – for the cooling of hydraulic or lubricating oils. The range has been extended to include slow-running ventilators and the housings have been optimised in order to make the cooler range as comprehensive as possible. The smaller models are also available as single or dual versions, thus covering oil-cooling requirements for both low and high oil flow rates.

Product features

  • Cooling of: oil, HFA, HFB, HFC, HFD fluids up to
    v=100 x 10-6 m²/s, water/glycol at least 65:35 – under no circumstances water without corrosion prevention
  • Coolant: air
  • Variable motor; Hydro /12/24V


  • Compact oil cooler
  • High cooling performance
  • Low pressure loss
  • High flexibility
Series TFS/A

The TFS/A is a compact partial flow cooling unit. It has been developed to improve the availability and reliability of hydraulic systems. Due to its combination of a motor pump unit and an oil air cooler in one device, the TFS/A is an autonomous unit, which can be operated independently of the main system. Thereby, continuous cooling is ensured.
