    we have two types 330 Heat Transfer Fluids, RFCTHERM-330A and RFCTHERM-330B, detail is below:

    RFCTHERM-330A


    Product Description
    CAS #: 28299-41-4

    RFCTHERM-330A is a mixture of Xylyl Ethers, it is a synthetic heat transfer fluid designed to meet liquid phase systems.RFCTHERM-330A has excellent thermal stability and Low Temperature Pumpability, It was developed for use at temperatures between -30 and 330, Low viscosity at exceptionally cold temperatures makes it to be an ideal fluid for extreme climates. It is miscible and interchangeable with other similarly constituted Xylyl Ethers fluids, such as: Diphyl DT

    The Temperature Range for use

    Liquid : -30 to 330


    Applications

     It can be used in a wide variety of industries, such as:

    ·         Chemicals

    ·         Refining

    ·         Oil and Gas Processing
