Project Description


  • CGT 64C
  • CGT 64C
  • CGT 64C
  • Design construction available with
    finned tube, water or air coolers with fan
  • Barrier pressure is created without any
    need for connection to a nitrogen
  • Modular design combination available
    with a wide variety of system
    components and instruments selection
  • Pressurisation is achieved through a
    pre-loaded bladder accumulator
  • Nitrogen cannot get into the barrier
    medium or process medium, because it
    is separated from the barrier medium by
    membranes in the accumulator
  • The BFS is designed to perform the following
    functions of a barrier system:
  • To pressurize the barrier chamber
  • Leakage compensation
  • To cool the seal
  • Pressurization (> process pressure) prevents the
    process medium from getting into the barrier circuit or
    the atmosphere. Pressurization is supplied by a
    pressure accumulator which is pre-loaded with
    nitrogen. Circulation in the barrier circuit takes place by
    the thermosiphon principle or by forced circulation, e.g.
    with a pumping screw.

  • Pressurised barrier system (closed circuit) is
    employed for applications in sealing systems
    with operating parameters of high pressures
    and/or for hazardous/environmentally
    harmful processes. The BFS (Plan 53B)
    range is available with a pressure
    accumulator, cooler (finned tube or water or
    air cooler with fan) with a wide range of
