Rim Seal Foam Pourer is designed to discharge fully aspirated foam directly to the annular seal area of the open top floating roof storage tanks for fire or
- vapor suppression. Fully aspirated foam provides the most effective performance. HD rim seal foam pourer is UL Listed and FM Approved. The rim seal foam
- pourer design provides protection from the wind, allowing the aspirated foam to gently discharge onto the protected area of the floating roof tank. Gentle
- application minimizes submergence and agitation, increasing the effectiveness of the foam blanket. This design allows a uniform and cohesive foam flow. The
- rim seal foam pourer is used in one of the most common applications of protecting tank seal in vertical liquid storage tank with internal floating roof with low
- expansion foam system.
