    01
    Characteristics
    1. Separation efficiency of over 95% is available, to use under general conditions and appropriate velocity.
    2. Over 98% open area is guaranteed under all usage conditions so Pressure drop can be ignored caused by the use of the DEMISTER. (0.1”–1.0 W/G)
    3. It can be made of any material suitable for the given temperature and corrosion- resistance.
    4. It’s available to install by use of M/H ( manhole) So it’s easy handling.
    5. No restrictions on usage conditions, place and Size. It’s also installable on existing devices.
    6. Self-cleaning is possible. It is semi-permanent so it’s economical.

    Material
    It can be made of various material based on each usage on the application. The main materials are as follows:
    Stainless Steel
    ( STS304, STS316, STS316L ),
    Monel, Duplex, etc.
    P.P (Poly Prorylene),
    P.E (Poly Ethylene), HPE, etc.
    Glass Fiber

    Characteristics by demister style
    DSM-800 Usgae conditions for the case that high velocity and low pressure drop is required,
    or collecting larger particles, no need high efficiency. It’s used for general collection efficiency. (Heavy processing type)
    DSM-1440 The type is widely used in petrochemical plants and as a standard type for general efficiency purposes.
    Pressure drop is relatively small, and the collection Efficiency is typically 90 to 99%. (Standard type)
    DSM-1905 Most commonly used as a High-efficiency Standard type. Generally, it has an collection efficiency of
    90 to 99% for particles of about 10micron. (High-efficiency standard type)
    DSM-3903 Twice the structure of standsrd type. In particular, it’s used for high efficiency is required.
    The Pressure drop may increase, but efficiency is over 90% at a low velocity 1 m/sec or less
    DSM-2205 Used to collect fine particles of about 3micron In particular, in the case of low concentration, when the quanity of mist (dust) is less than 10 g/m³, the collection efficiency can be doubled as the thickness is increased. ( High -efficiency type )
    DSM-4320 Used for collecting ultrafine particles Measuring less than 0.5–1 micron; higher effectiveness than the DSM-2205 style can be achieved. (Ultra high-efficiency type)
    DSM-JM Manufactured as a composite structure of DEMISTER element, according to the usage conditions.
    High-efficiency performance is required under limited usage conditions

    Performance
    Air pollution prevention
    Removing harmful substances from gas
    Improving product purity
    Removing impurities from gas
    Cost reduction
    Preventing the scattering of the product’s raw materials
    Extending plant life and providing an energy-saving effect
    Collecting mist separately by installing in the pre- and post-plant processes

    05

    Installment and Grid
    The DEMISTER should be horizontally fixed and Supported. Generally, a support grid is used on the bottom or top& bottom both sides using F/B 25 x 3t and R/B 6Ø made of the same material as that of the DEMISTER pad at proper intervals (approximately 150 mm), is used . The grid and pad are fixed using R/B 6Ø or 1.6Ø tie wire, The way of fixing as shown in the figure bellow.
