    Benefits of Conditioned Oil

    All high capacity transformers in use today have to cope with voltages in excess of 400kV. Therefore, it becomes imperative to maintain optimal insulation properties of the transformer oils by rigid control over moisture, dissolved gas and particulate contamination. Otherwise, there is a considerable decrease in its BREAK DOWN VOLTAGE, INSULATION RESISTANCE, and increase in DIELECTRIC LOSS FACTOR. Conditioning saves the cost of using new oil frequently and also increases the life of the transformer. Even commercial oil is seldom sufficiently pure for direct use in high voltage, equipment, being subject to contamination in Transport Containers and liable to absorb unacceptable contaminants and moisture.

    Fowler Westrup (India) Private Limited takes pride in its ability to provide equipment specifically designed to meet customer requirements and specifications at a reasonable cost, Advanced designing models permit economical and rapid custom system development, ensuring customer satisfaction and smooth integration processes.


    Fowler Westrup (India) Private Limited offers a complete range of models to meet demanding applications.

    Medium High Vaccum
    High Vaccum
    Ultra High Vaccum
    JMHV Model
    JHV Model
    JHVR Model

    With flow capacities ranging from 200 to 12000 litres per hour (LPH)

    The above models are available in both single & multi-stage degassing chambers. Multistage models find applications in Power Transformers and forms a sizeable population Flow capacities in excess of 3000 LPH employ standard multistage conditioning systems (in the case of High Vaccum and Ultra-high Vacuum models).

    The above models can be configured in a variety of options:

    Skid Mounted
    Mobile - trolley mounted
    Mobile - truck mounted
    Process units for special applications
