Removing condensed oil - water emulsion from air purification systems
Removing Condensed Oil -Water Emulsion From Air PurificationSystems inorder for an air purification system to operate satisfactorily it is imperative that the resulting condensate is removed the use of an appropriate

ne of the pre-conditions for effifiltration and drying of air and gases is a well functioning, reliable condensate drain capable of removing the condensed oilwater emulsion from the system. Condensate consisting mainly of water can be disposed of by using a drain with sensors and small orifices. On the other hand, oily condensates must use a drain with a large orifice and other control methods. On small systems the most important factor is to avoid the loss of expensive compressed air by unnecessarily opening drain valves and on larger systems, factors such as the quantity of condensate that the drain can handle and the need for an alarm function to indicate an overload are of utmost importance - ultrafilter has recently introduced a range of condensate drains designed for specific applications and working environments.
The operating pressure contained by the collection vessel acts against the diaphragm (1) and causes it to separate the condensate channel (pressure side) from the exit channel. However, when sufficient condensate has been collected, the float is lifted. This permits compressed air to enter the surge chamber through the control valve. The diaphragm (2) is pressed to the right and opens diaphragm (1) by means of the piston. The condensate drams to the exit through the condensate and exit channels. Should the float fall below a position determined by a drop in the condensate level, thus closing the control valve again, the surge chamber is vented through the nozzle. Diaphragms (1) & (2) return to their starting position, forcing the drain to close. The outlet valve can be tested by means of the hand valve.
Pneumatic control
The ultramat plus tronic (UFM-T) combines the advantages of the pneumatically operated system with an electronic control and alarm function. The system combines a float mechanism with a servo valve that controls the opening and closing of a large orifice through which viscous condensate can flow. As was the case with the ultramat condensate drips plus pneumo, through the intake port and is collected. As the solenoid float rises to position (2)due to the increasing condensate level, a protective gas contact
The pneumatically controlled ultramat plus pneumo (UFM-P) does not require an energy source and therefore can be used in explosion risk areas or used during the cleaning of explosive gases. The stainless steel float actuates a pneumatic control system that allows the condensate to escape through a large orifice without losing compressed air. Condensate drips through the intake port and is collected. The control valve is initially closed and the surge chamber is vented.

is activated inside the float pipe. This contact in turn activates the solenoid valve within the electronic control unit. Up to this point the pressure chamber associated with the main valve had been under pressure via the solenoid valve. The pressure chamber is now vented and the diaphragm opens the way for the condensate wia the boring and the valve seat. As the condensate level falls, the float returns to position (I), and the pre-control valve is close again by another protective gas contact. The pressure chamber is loaded again with compressed air and the main valve is closed. The cycle is then repeated. Should the float reach position (3) due to a malfunction, the light emitting diode fitted into the housing cap, flashes denoting a fault. Manual operation is facilitated by the feeler, enabling the float position to be simulated and as long as the feeler is pressed the drainage will continue.
