Case Study – Customized Cooling System for Agricultural Machines

Customized cooling system

Vivoil and ASA Hydraulik together to implement the system

Vivoil hydraulic products are used in many sectors. One of the most important is certainly the agricultural one. Also in this field the ability to customize the components is essential to achieve certain performance or integrate a specific function in the machine, and it is precisely in these cases that we are commissioned particular components. An example is the hydraulic motor/pump unit 8 cm³ – 17 cm³, designed in collaboration with our partner ASA Hydraulik for a major manufacturer of tractors, harvesters, sowing machines, soil tillage.

The request: design an axle-cooling system with hydraulic drive

In 2015, a major world producer of agricultural machinery commissioned our partner ASA Hydraulik to build an axle cooling system that could take oil from the axles and retransmit it to both the rear and front axles of its machines.

ASA Hydraulik is an Austrian company with 40 years of experience and over 21 global patents, specialized in the production of cooling equipment and other special components. This important project has entrusted us with the task of creating a compact motor + pump system capable of managing with a modest quantity of oil in supply both the cooling circuit through the pump and the fan.

The solution: ASA air / air cooling unit + Vivoil pump unit motor

Together with ASA Hydraulik we have therefore studied a tailor-made solution with these characteristics:

  • At Vivoil we have designed a hydraulic motor/pump unit 8 cm³ – 17 cm³, with these technical specifications:
    • engine with external exhaust system
    • BSPP engine ports ½ “- ½” / BSPP pump ports ¾ “- ½”
  • ASA Hydraulik has designed a TT 07 oil / air cooling unit with a pump / motor DC power supply (ASATT07GH08CCB00), with these specifications:
    • Aluminium radiator “plate and bar” (26 bar static)
    • “easy clean” wavy air fins
    • patented ASA rail system
    • circulation (offline) cooling with integrated pump
    • “heavy duty” foot configuration
    • reflector label for fan speed measuring


The results

Thanks to this ad hoc solution, we not only managed to create a cooling system in line with customer requirements, but the temperature of the axle was stable at 66 ° C.

The type of oil used is 80W90. The required cooling: 5.2kW @ 30 lpm / ΔT = 40 ° C / 2000 rpm travel speed.

Designing this innovative solution together with ASA Hydraulik was an opportunity to once again appreciate the precision and professionalism of our partner.

Here is their testimony:

“We have been collaborating with Vivoil for many years because we know we can count on a reliable, competent and expert partner, able to always find the most suitable component for the customization requests that come to us from our customers.”
