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.

•The WFD 01 – Indicator is an efficient diagnostic tool to determine both the saturation
level of oil with water and the contamination level of the filter element
•It utilizes the WSPS0X (03/ 04/ 05) as well as a VS 1 series clogging indicator. It works
very reliably and fulfils all requirements of daily measurements.
•It consists of two separate and independent LED – display units with separate power
supply.
„Water Saturation Level (%)“: The LED – display for the indication of the water
saturation level is a mere indicator.
„Clogging Indicator“: The LED – display to indicate the contamination of
the filter element has two voltage free relay switch
contacts. One at 75 % and one at 100 % of the
VS1‘s nominal pressure difference range and cold
start indication at oil temperatures < 25 °C.
4.6.1. Water saturation display
- (0...70% Saturation)
The presence of free water is not likely. There is no danger of water dissolved in oil!
- (70...90% Saturation)
The presence of free water in small amounts is likely.Measures to reduce the water
content are suggested.
- (90...100% Saturation)
- Free water is present. This is dangerous for the hydraulic and the lubrication system.
Measures to reduce the water content of the fluid have to be taken
immediately!
•A calculation to the mg/kg (ppm) – water content is only possible with the 100%
saturation curve. This must be determined for every oil. Saturation curves on request.

4.7. Input and output seizure
•The digital inputs of the PLC are used as follows:
Input N° Function
1 lower sensor (min.)
2 middle sensor (max)
3 upper sensor (Overcharge lock)
4 signal "filter clogged"
5 oil level switch for the vacuum pump
6 motor protector hydraulic pump
7 motor protector vacuum pump
•The temperature sensor of the vacuum chamber is connected to the analogue input
N°1.
•The temperature sensor of the heating element is connected to the analogue input
N°2.

17
•The different components of the system are controlled by the following digital outputs of
the PLC:
Output N°
Function
1 hydraulic pump
2 vacuum pump
3 heating
4 solenoid valve
6 signal light for low oil level in the vacuum pump
•The digital input signals and outputs can be either ON (LED is light) or OFF (LED is
dark).
4.8. Other
•With the buttons [] (Temp. up) respectively [] (Temp. down) the switch off
temperature can be set.
•At achieving of the set temperature the preheater switches off, if the actual oil
temperature is again lower than the set temperature the preheater is switched on again.
Please note that the set temperature value is only a switch off criteria. It
cannot be assured that the oil temperature actually reaches that setpoint.
The surface area of the heating can be more than 70°C during
operation . Risk of burns!
•The humid air of the vacuum pump will be led through a moisture separator and then
emitted to the atmosphere.
The level of the reservoir should be checked daily.
•The collected humidity in the condenser can be discharged with the ball valve
“Water out”
•Most of the separated water will leave the IFPM/S as humid air.
At lower water contents in the oil there will hardly be any water collected
in the condenser.
It is not a mistake if no water is collected in the separator. This only
indicates low water content or low temperature of the oil.
•The vacuum in the vacuum chamber can be adjusted with opening and closing the
throttle valve (5).
The optimum vacuum and the optimum temperature depend on the fluid
type which should be dewatered and on its condition. The vacuum should not be
higher than -0,9 bar and not lower than -0,6 bar.
•The actual flow rate depends on the following parameters:

18
ooil viscosity
ooil temperature
oadjusted vacuum
olength and cross section of the suction line
oposition of the IFPM/S relative to the reservoir
In exceptional cases, for example at very high tanks, the vacuum
chamber can overflow. This can be detected, if oil comes out at the separator. In
these cases it is suggested to throttle the suction line, for example with the inlet
ball valve.
5. Failure messages
•In case of malfunction of a component, the system will shut off and one of the following
messages will appear in the display:
- No oil
- Overflow
- Filter clogged
- No lubricating oil in v – pump
- Motor overload hydraulic pump
- Motor overload vacuum pump
5.1. No oil
•This message will be displayed if no fluid reaches the lowest level switch after a certain
amount of time. The reasons for this error could be the following:
- high viscosity
- small diameter of the suction line or too long suction line
- suction height to high
- closed inlet ball valve
- contaminated solenoid valve

19
5.2. Overflow
•This message will be displayed, if at closed solenoid valve and running hydraulic pump
the oil level reached the highest level switch for a certain amount of time.
•The reaction time is determined by the chosen viscosity during the starting procedure
•The reasons for this error could be the following:
- chosen a wrong viscosity
- high vacuum
- defect hydraulic pump
- clogged pressure line
5.3. Filter clogged
•This message indicates a clogged particulate filter element.
⇒Exchange filter element and restart the system
5.4. No lubricating oil in v-pump
•Indicates a low oil level in the vacuum pump
•This can be caused by clogging the coalescent element of the vacuum pump and the
loss of oil related to that.
⇒Exchange the coalescent element, fill up oil and restart the system.

20
5.5. Motor overload hydraulic pump
•This message will be displayed, if the switch to protect the motor of the hydraulic pump
is activated.
⇒Check the power supply, all three phases must be present.
