Specific cooling capacity Pspez [W/K] Cooling capacity Flow rate Q [l/min] The specific cooling capacity indicated in the graph was determined on the test bench, test oil ISO VG 46, oil-inlet temperature 60°C. The actual cooling capacity may deviate by approx. ± 5 % depending on the installation site and other operating parameters.

Conversion factors viscosity The correction factor has to be used for the calculation of the pressure drop for other viscosities:

Example 1: Cooling capacity known Example 2: Cooling capacity unknown The heattransfer to the oil is approx. 30% of the motor power (diesel/electric motor) Cooling capacity Oil inlet température Ambient temperature Oil flow Motor power PMotor = 45 kW Cooling capacity P = 13.5 kW Oil inlet temperature TOil = 50°C Ambient temperature TAir = 20°C Oil flow QOil = 200 l/min Specific cooling capacity: TOil - TAir Specific cooling capacity: TOil - TAir Sélection of cooler type: Selection of cooler type: Calculation of temperature difference:

Installation instructions If possible, the heat exchanger should be integrated into the system with suitable hydraulic hoses. In the case of rigid piping, compensators are one way of eliminating introduction of forces via the piping. Pressure peaks in the system can lead to fatigue failure of the heat exchanger, even if they are below the permissible operating pressure. The frequency of the peaks is the influencing variable. 7 Support of electric engine
