    Steam Traps E Series | Inverted Bucket Steam Traps ESH21

    Features/Applications

    Features

    • No condensate logging on primary side

      Intermittent or continuous discharge depending on condensate loads means no condensate stacking up on the primary side.

    • Superb durability

      Offers superb durability thanks to the SCCV System valve and robust super lever, as well as stainless steel internal components.

    • Easy maintenance

      For quick and easy maintenance, this model can be repaired directly in line.

    • Condensate recovery

      With its high degree of back pressure tolerance, this model supports condensate recovery at pressures up to 90% of the upstream pressure.

    • Complete steam containment

      A double steam separation mechanism (implemented with a U-shaped duct and inverted bucket) provides reliable steam separation and ensures trap tightness.

    • Free from steam and air locking

      This model is free from steam and air locking due to a small air vent hole in the top of the bucket (discharges hot air and non-condensable gases).

    *’SCCV System’ is an abbreviation of Self Closing and Centering Valve System.

    Typical applications

    Suitable for use in a wide range of fields including the plant industry, foodstuff manufacturing, dyeing, cleaning, and air conditioning.

    Installation Examples

    ES_haikan.png

    ●To keep the drawing simple, bypass pipes, bypass valves, and other such things are not displayed. You should use these products as necessary.
    ●If you wish to recover condensate, attach a check valve (CV model) and valve on the trap’s outlet side.
