Foam Proportioning Equipment

Atmospheric Foam Concentrate Storage Tank is storage device which used for storage of large amounts of foam. Foam storage tanks are suitable for storing synthetic AFFF, alcohol-resistant AFFF or fluoroprotein foam concentrates. Typically the in line proportioner is connected between foam storage tank and bladder tank as the foam gets drained out after its usage of suppression. Foam from foam storage tank are used to fill into bladder tank.

• Capacity: 200 L – 50,000 L
• Designed as per ASME Sec VIII, Div. 1
• Body: Stainless steel/Carbon steel with FRP lining
• Available in horizontal & vertical mounting
• Flat end & dome end

FIRETECH Bladder Type Foam Proportioning Unit (Bladder Tank) is provided for accurate foam proportioning of the foam concentrate with the fire-water over a wide range of flow.

FIRETECH Horizontal and Vertical Bladder Tanks consist of the following main components i.e. Foam Vessel, Foam Bladder, Water Piping, Foam Piping, Vent & Drain Valves and Level Indicator.

During operation the water is charged into the bladder tank between the vessel wall and the bladder to the inlet water pressure. Bladders transfers this water pressure to the foam concentrate stored inside the bladder, this causes pressurization of the foam concentrate.

Pressurized foam concentrate is delivered to the foam concentrate inlet of the foam proportioner. A foam concentrate orifice is provided for accurate mixing of the foam concentrate into the fire-water.

The metering pressure drop is created in the foam proportioner which causes the foam concentrate to flow into the fire water stream.

Bladder tanks with horizontal layout are referred as horizontal bladder tanks. Firetech manufactures UL Certified Horizontal Bladder tank from range of 200L to 15000L capacity.

Bladder tanks are also available in vertical layout. They functions same as Horizontal Bladder Tank only difference. In vertical bladder tanks, water enters the tank from left side and forced out foam from right side or vice versa. Vertical bladder tanks are preferred in case of space constraint.

Firetech manufactures UL Certified Vertical Bladder Tank from range of 200L to 15000L capacity.

• Capacity: 53 Gal. to 4000 Gal. (200 L to 15,000 L)
• Foam Proportioners: 50 NB to 200 NB
• Wide Flow Range: 75 LPM to 30,000 LPM
• Foam Vessel: Carbon Steel / Stainless Steel
• Bladder: Nylon Reinforced Nitrile (BUNA-N)
• Designed as per ASME Sec. VIII DivI 1
• Rated Pressure: 12 Bar (175 psi)kg/cm2
• Approvals – UL Listed, CE marked

FIRETECH Inline Balanced Pressure Foam Proportioner is used for accurate proportioning of Foam Concentrate & fire water to form foam solution over a wide range of flow & pressure. Inline Balanced Pressure Foam Proportioner (ILBP) is used with Positive Displacement Foam Pump and Atmospheric Foam Storage Tanks.

FIRETECH Inline Balance Pressure Foam Proportioner consist of following main components i.e Foam Proportioning body, pressure balancing valve, Pressure gauge Water & Foam, pressure trim hose, manual override valve.  

Positive displacement foam concentrate pump delivers pressurized foam Concentrate to the pressure balancing valve. Fire-water and foam Concentrate pressure at inlet of foam Proportioner is displayed by the water pressure gauge and foam pressure gauge inline balance foam Proportioner will accurately proportion the required amount of foam concentrate into fire-water stream over a wide range of flow and pressure.

Firetech ILBP can be provided with or without Manual Over-ride.

• Flow range from 300 to 11,000 LPM
• Stainless Steel Construction (SS 304 & SS 316)
• Working Pressure: 3 to 12 kg/cm2
• Flanged End Connection
• Manual override not required
• Compact in Size
• Approvals – UL Listed

Fixed inline foam inductors are designed primarily for use in fixed installations to provide a simple and reliable method of proportioning foam concentrate in constant flow applications.
