Solving Hydraulic System Overheating Problems
If the system is overheating, it means that either there is a problem in the cooling circuit or the capacity of the exchanger is insufficient for the ambient operating conditions. On the other hand, if the measured temperature drop across the exchanger is 10ºC and the design oil flowrate is 90 L/min, the exchanger is dissipating 26 kW of heat.
