Marsh Ice Plug Freeze Jackets

It was recognized that current pipe freeze technologies, widely used in commercial applications, utilized a single wall device which although somewhat effective, produced a number of side effects which were not considered acceptable for nuclear and other high end applications with respect to human engineering and safety parameters.

Taking into account these shortfalls in pipe freeze technologies, Marsh has developed and produced an innovative "Ice Plug Freeze Jacket" incorporating the following features:

  • Double wall construction contains and controls the amount of freeze catalyst used
  • Double controlled venting minimizes the amount of freeze catalyst required to maintain the freeze.
  • Lightweight construction for easy installation / removal in congested areas.
  • All stainless steel construction
  • Cryogenically welded to withstand thermal cycling
  • Innovative clamp mechanism facilitates single hand tightening into position
  • Custom manufactured to meet individual / unique application specifications


Marsh manufactures the following types:

  • Single Vent Double Wall (SVDW) Ice Plug Jackets
  • Double Vent Double Wall (DVDW) Ice Plug Jackets

Marsh "Ice Plug Freeze Jacket" are designed to meet all applications in the Nuclear, Food and Petrochemical industries.
