3.3. Functional principle
• The oil is drawn into the system by a vacuum, generated by an oil lubricated rotary
vane vacuum pump (13).
• First it will pass a preheater (1), afterwards it goes into the vacuum chamber (3)
through a 2/2 solenoid valve (2).
• In the vacuum chamber the fluid will be dispersed over the dispersion material, which
creates a larger free surface.
• Water will vaporize due to the lowered evaporation point in vacuum.
• An air stream is introduced to the vacuum chamber through the silica-gel air filter (4).
The flow direction of this air is against the flow direction of the oil and it functions as a
carrier for the water vapour.
• The vacuum can be adjusted with a throttle valve (5).
• These conditions do not only help to remove the free water. Free, emulsified and
dissolved water will be removed.
• The humid air will be sucked by the vacuum pump and it is blown out trough a
condenser (14) and a demister (15) into the atmosphere.
• The oil will be pumped back into the reservoir with a hydraulic pump, which is specially
designed for vacuum operation.
4. Operation
4.1. Commissioning
The commissioning will be executed as follows:
• Connection of the IFPM/S to the oil reservoir.
• Electrical connection of the IFPM/S.
• Check the rotating direction of the motors.
• Remove the seal of the Silica-Gel air filter and open completely the throttle valve of the
air line.
• Emptying of the vacuum chamber.
• Selection of the viscosity range.
• Adjustment of the switch off temperature of the preheater.
4.1.1. Connection to the oil reservoir
• The IFPM/S should be installed near the oil reservoir.
At installation please make sure that the machine is in a level position.
If this is not possible make sure that the vacuum pump with the oil level switch
is located at the lower end of the system.
• The suction line can be closed with a ball valve.
• The oil outlet is after the filter with an SAE-flange
• Both lines must be fixed connected to the oil reservoir
