    Features/Applications

    Features

    • Compact and cost effective design

      It has a space saving, simple mechanism with very few moving components.

    • Easy maintenance

      The minimum of moving parts and an easy in-line access ensures easy and fast maintenance.

    • Flexible installation

      This product can be installed either horizontally or vertically.

    • Auto blow off and air vent

      Thanks to a bimetal ring, the trap smoothly discharges initial air and cold condensate. (Auto blow-off mechanism)

    • Tailored design

      Manufacturing with custom face-to-face dimensions is possible. 

    Typical applications

    Suitable for steam main lines, steam tracing, small steam equipment and other such applications
