FFM Series Foam Generators Floating roof storage tanks are generally protected using foam generators on the rim or roof to apply foam to the seal area. We manufacture a range of rim seal foam generators for this application. FR-50 Rim Seal Pourer In windy conditions rim mounted foam generators can suffer from significant loss of foam. We have designed the FR-50 rim seal pourer to alleviate this problem. The K-series tank cooling nozzle provide an efficient and economical method of providing exposure protection to petrochemical storage tanks. Two common methods of protecting fixed roof (cone roof) storage tanks are foam chambers and sub-surface injection. Both methods have their advantages and we manufacture high performance products for these systems. Foam Chambers Our CRP range of foam chambers are designed for ease of installation. High Back Pressure Foam Makers Our new range of high back pressure foam makers offer the best performance available. NEW: High flow rate, high performance high back pressure foam makers - and more economical too! High Back Pressure Foam Maker Datasheet.
