Engineered Systems Application & Design


CHEMGUARD custom systems are manufactured to meet and exceed the performance standards of harsh environments, such as this freeze-protected, insulated horizontal bladder tank.


CHEMGUARD has the largest and most diverse UL Listed high-expansion foam system product line in the industry, including high-expansion foam concentrates, portable handline nozzles, and water-, electric-, and diesel-powered high-expansion foam generators.

The CHEMGUARD product line of engineered fire suppression systems ensure a rapid, thorough, and economical response to fires and spills. Customized to application specifications, our dependable engineered systems include bladder tanks and pump-type balanced-pressure proportioning systems; in-line balanced-pressure proportioning systems; high-expansion foam systems; large dry chemical systems and skids; twin-agent systems and skids; foam trailers; large dry chemical and twin-agent trailers; monitor trailers; aqueous film-forming foam (AFFF) pump systems; water-powered AFFF pump skids; foam/water monitors; nozzles; eductors; ratio-flow controllers; foam makers; foam chambers, and specialized proportioning storage and monitor trailers.

CHEMGUARD UL-listed high-expansion foam systems pair premium foam concentrate with high output foam generators to provide firefighting protection for a multitude of applications: aircraft hangars; basements; cable tunnels; flammable packaging areas; flammable liquid drum storage areas; hazardous waste facilities; LNG tank farms and loading facilities; mines; roll-paper warehouses; shipboard engine rooms, bilges, and holds; storage buildings; warehouses; and wildland fire breaks. The light, voluminous foam blanket produced by our high-expansion foam systems can quickly obtain great heights, reaching elevated flammable materials (such as on storage racks). The foam blanket efficiently transports small amounts of water to the fire, encapsulating the flammable vapors and causing suppression and extinguishment.

CHEMGUARD foam systems can be designed and engineered for specific application requirements, such as use in harsh environments.
