Discharge Devices

Foam Chambers   Data sheet

Designed to deliver foam directly onto the surface of flammable or combustible liquid and lessen submergence of the foam, foam chambers are installed on flammable liquid storage tanks just below the roof joint. Flow rates for these UL Listed, type 2 discharge devices (NFPA 11), can vary, depending on the application. Foam solution is supplied to a chamber from outside the hazard area, either from a fixed foam-storage and proportioning system or from a dry-pipe semi-fixed system that receives foam solution from a mobile foam apparatus. Upon entering the chamber the foam solution is expanded and then discharged against a deflector mounted inside the storage tank. The deflector (split or solid) directs the foam against the inside wall of the storage tank, reducing the agitation of the fuel. Chemguard foam chambers are suitable for use with hydrocarbons or polar solvent fuels, as well as with all low-expansion foam concentrates, proteins, and synthetics.

Foam Makers   Data sheet

Designed as air aspirating discharge devices, Chemguard foam makers are used principally for the protection of dikes, open floating-roof storage tanks, and rim seals, and where low-velocity foam streams are desired. Foam makers generally are installed in the line of a semi-fixed or fixed foam fire-protection system, mounted either horizontally or vertically. UL Listed, Chemguard's foam makers feature all-brass construction for use in harsh and corrosive environments. Foam maker air inlets are covered with stainless tell mesh, and the foam makers are supplied with standard NPT threaded inlets and outlets.

Water Powered Oscillating Monitor   Data sheet

Chemguard Water Powered Oscillating Monitors are designed to automatically discharge over a specific design area upon system activation. These are suitable for use in high risk areas such as tank farm facilities, aircraft hangars, offshore, refineries, chemical plants, and heliports.

Monitor Nozzles   

Available for use with our full line of monitors, for water and foam solutions, Chemguard nozzles provide flow rates of 100 to 1,250 gallons per minute, with flows up to 5,000 gallons per minute possible on high-volume mobile/trailer units. Manufactured from corrosion-resistant brass or durable Chemlite™ anodized black aluminum, Chemguard nozzles are fully adjustable, from straight stream to full fog. Serrated teeth improve the water fog pattern and aid foaming AFFF solutions. Non-aspirating water fog nozzles are used for aqueous film-forming foam (AFFF) applications; aspirating nozzles are used for polar solvent fuels and fluoroprotein foam solutions. Chemguard’s master-stream monitor nozzles are offered in fixed-gallonage, adjustable-gallonage, automatic, and self-educting versions.
