Foam Discharge Equipment

Foam maker is a discharge device used for protection of open floating-roof storage tank where low velocity foam streams are desired. Its working principle is same as that of foam chamber, only difference being foam maker allows foam to flow directly without storage. As per NFPA-11 they are defined as Type-II Discharge Outlets used for Producing Low Expansion Foam.

During operation the Flow of foam solution under pressure causes induction of air through Air Strainer. Inducted air causes aspiration and low expansion foam is produced.

Firetech manufactured foam maker are available in carbon steel & stainless steel (304 & 316), ranging from 80 NB to 150 NB size with a flow rate from 66.24 lpm to 1477 lpm (17.5 to 390 gpm)

• Size: 50 NB, 65 NB & 80 NB
• Flow Range from 66 LPM to 1,476 LPM
• Carbon Steel & Stainless Steel Construction
• Working Pressure: 2.1 – 7 Kg/cm2
• Flanged End Connection
• Approvals – UL Listed

Foam chambers are discharge outlet used with bladder tanks, pressure pump proportioners and foam storage tanks. They are basically located or installed on the line proportioners near to the outlet of the fuel tank to deliver foam to the surface of a flammable liquid. Foam chamber consist of glass vapour seal located in the body. As the seal break foam enters inside fuel tank or fuel surface to suppress the fuel carrying heat.

Firetech manufactured foam chamber of carbon steel material & stainless steel material ( 304 & 316) ranging from 80 NB to 200 NB size with a flow rate from 66.24 LPM to 2840 LPM (17.5 to 750 GPM).

Portable inline foam inductor works on the same principle as fixed inline foam inductor. They are designed to be removed and replaced anytime. Firetech portable inductors are designed for use in the manual firefighting operation in field to provide a simple, reliable and on spot method of proportioning in constant flow applications. Firetech Inductor is designed at pre-determined water pressure to give the exact proportioning at that pressure and discharge rate.

• Material- Aluminium Alloy & Stainless Steel (304 & 316 )
• Flow range- 225 to 900 lpm
• Operating pressure- 7 to 10 bar

Foam pourer are used with the foam maker to direct discharge foam directly to the annular seal area of the open top floating roof storage tank for fire or vapour suppression. Firetech equipment & systems manufactured foam pourer of carbon steel material & stainless-steel material (304 & 316) ranging from 80 NB to 150 NB size.

• Size: 80 NB, 100 NB & 150 NB
• Carbon Steel & Stainless-Steel Construction
• Compatible with Flanges: ANSI B 16.5, 150 #
• Used with foam maker for floating roof tanks
• Approvals – UL Listed

Firetech Foam Branch pipes are designed to produce long coherent throws of low expansion foam using all types of foam concentrates. Foam Branch pipes are air aspirating type devices typically made of Stainless steel, they provide the means for the production of mechanical foam used for fighting fires in flammable liquids. Similarly, mechanical foam is also used to cover flammable liquid spills to prevent ignition.

• Material- Aluminum/ Stainless Steel
• Inlet Connection- 2 Instantaneous
• Working Pressure 100 PSI Max.
• Foam Expansion 6 to 10 times
• Foam Induction Available with foam inductor or without foam Inductor
