Restoring machine uptime for a track builder.

In the factory of a company which specialises in the manufacturing of tracks and rail components, limitations in the production occurred. The operation of a track drilling unit with improved performance leads to a reoccurring overload of their two chillers which are connected, causing downtime for the machines.

Application requirement.

Reliable oil cooling of a high performance track drilling unit. Safeguarding the machine uptime also at lunchtime and in the afternoon when the production hall is heated by sunrays.

The Pfannenberg solution.

An analysis carried out on location with the customer revealed that the cooling capacity of the two chillers no longer corresponded with the current requirements. In order to counter the increased performance of the track drilling unit with an appropriate cooling performance, the cooling system had to be redesigned. Taking the temporarily high ambient temperatures in the production hall into account, the clear solution was a high performance chiller type EB 90. This unit has an integrated control module which provides a precise temperature control of the cooling medium.

The solution excels due to:

  • Separate cooling and hydraulic circuits.
  • Control module to program small hysteresis of the oil temperature.
  • Use at ambient temperatures of up to +40 °C.
  • Sturdy steel housing with thick powder coating.

Implementation.

As a result of our experts’ on site analysis, the company saved a costly and insufficient repair of the old chiller systems. Using a new solution that is tailor-made to meet current needs ensures the desired machine uptime – also in the hot lunchtime period. A supplementary maintenance contract was made, ensuring the optimal functionality in the long term.
