tem. This ensures water-free oil discharge.By way of analogy with theSMS, the diverted flow on this occasionis channelled via a conductivity sensor.If this device senses water, it opens asolenoid valve and the water is dischargedinto the dirty water discharge. Ifthe conductivity changes as a result ofoil flow, this solenoid valve closes, asecond solenoid valves opens intermittentlyand enables the flow of liquid tobe recycled back into the dirty oil feed.WMS and SMS are small but extremelyeffective aids to efficient heavy oil processing.Most powerful machine forheavy oil processingFollowing the introduction of its D-Type series, Westfalia Separator hasbeen overrun by users. Since the firstpresentation in mid-2002, orders havebeen placed for around 1,500 D-Typeseparators within a year. These machineshave opened up new dimensionsin centrifugal processing in the shippingindustry (gas turbines and dieselengines) as well as in power stations,oil production and industry. With evenbetter separating efficiency, lowerfresh water consumption, extendedmaintenance intervals and reducedweight, the D-Type separators meet thedemands created as a result of shipsbecoming faster and faster as well aslarger and larger. The flat belt insteadof a gear ensures simpler maintenancedue to a 30 % reductionin the numberof components, less Jürgen Mackelsusceptibility tovibrations, low-noiseoperation, lessweight and bettervalue for money.With the four sizes OSD 6, 18, 35and 60, Westfalia Separator is able tocover all ratings currently required bythe market. The OSD 60 is also the mostpowerful machine available on themarket for processing heavy fuel oil.The modular design of the compactunits has also been very well received.This uniformity of the D-Type designallows easy maintenance of all sizes ofmachine. ■Head of Development and DesignWestfalia Separator Mineraloil Systems, OeldeTel.: + 49 25 22/77-27 07mackel.juergen@gea-westfalia.deSeparator´s World27Separator´s Digest 1/2004
