    Cyclone Separators for Steam (with Built-in Trap)

    DC Series

    Why a Separator is Necessary

    High velocity condensate flows through the drip leg

    Drip legs are designed to remove a considerable portion of the condensate flowing through piping – that which has fallen out of the steam flow, but cannot remove the water droplets entrained within the flow itself.

    Cut-view of Condensate Discharge Through Drip Leg

    Water droplets entrained in steam will be carried over and pass by the drip leg because of the speed at which steam flows through piping.

    Negative Impact of Condensate Droplets in Steam Processes

    Elbow in Piping

    Water droplets may lead to the formation of pin holes from LDI erosion at elbows in the piping.

    Direct Heating Application

    Water droplets may cause product defects when coming in direct contact with the product being heated, or reduce heating quality / efficiency when contacting heat transfer surfaces.

    Separating Condensate from Steam

    DC Series: Up to 98% Separation Efficiency

    Condensate entrained in steam is mechanically removed using a cyclone separator for steam.

    How condensate and water droplets are mechanically removed from steam

    Centrifugal force is used to separate entrained water droplets from steam, by taking advantage of the difference in the specific gravities of liquid and gas to separate the two. In this case, steam is channeled into a spiral flow, causing the heavier condensate droplets to be flung out of the flow and onto the inner wall of the separator. Gravity then pulls the condensate down to the bottom of the separator where a built-in free float steam trap is installed to discharge it.

    Super Cyclonic Effects separator (SCE)

    The DC series separators use a cyclone separator to separate and remove water droplets from steam with 98% efficiency (at a flow velocity of 30 m/s). High velocity centrifugal force and directional changes are key factors that enable such a high degree of separation.

    Free Float® Steam Trap

    The Free Float® enables continuous discharge of condensate while still keeping a steam-tight seal. This rapid discharge design with no back-up is essential to prevent condensate from being re-entrained into the steam flow.
