Oil air cooler for industrial operation Product features • Noise level reduction due to axial fan blades of the latest design • Streamlined fan housing for optimisation of the air flow • Air fins insensitive to contamination • Static test pressure 25 bar according to DIN 50104 • Peak pressure resistance at 16 bar and 1 x 106 load cycles, f = 1Hz • Operating pressure: 16 bar • Max. operating temperature: 120°C Powder-coated housing • Drive motor: 230 - 400V, 50Hz (DC version 12/24V on request) Operation with all common hydraulic fluids of different viscosities (oil, HFA, HFC, etc.) Cooling...

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.

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. 1 Cooler block 2 Fan housing 3 Axial fan 4 Protection grid 5 Electric engine 6 Mounting brackets ACI-71 to ACI-101 2 1 Cooler block 2 Fan housing 3 Axial fan 4...
