Oil cooler in aluminium, suggested for hydraulic cranes.
The air/oil coolers are available for power packs, hydraulic cranes, excavators and other hydraulic machinery. The are equipped with electrical fans of 12V or 24V and, due to their great resilience, can be installed on all types of machinary, even with the strongest vibrations with the vibration dumpings installation.
. The oil flow indicated in the leaflet, are suggested for the best performance of the oil cooler.
. The loss of pressure, indicated for each oil cooler does not exceed 1 Bar.
. The standard temperature of intervention of the fans is 40-48°C. Other settings starting from 30-38°C to 50-60°C are available on request.
. As a general rule the oil cooler must be installed on the low pressure tank return line. The oil cooler must be mounted in such a way as to ensure that there are no obstacles to the flow of the air, either at the intake or at the outlet of the oil cooler core. In order t0 achieve the maximum possible rate of exchange it is good pratice to ensure that the inlet port is physically lower than the outlet port (see diagram).
. It is necessary when isntalling the oil cooler to use the dimensions (diameter) where the tubes are to be attached on the enter/excit section, as indicated in the technical information.
. To protect the oil cooler system in cold engine start-up and when oil flows are variable, it is advisable to mount a by-pass valve on the entrance section of the tubes.
