Fire Suppression 50 Gallon Foam Bladder Tank For Fire Fightin
Foam Bladder Tanks offer a reliable and simpler method of foam proportioning. Bladder Tank system includes a pressure-rated tank with an internal rubber bladder. Upon system actuation, incoming water applies pressure to the rubber bladder, which supplies pressurized foam concentrate to the proportioning device (ratio controller). The foam ratio controller meters the foam concentrate into the fire water line, creating a foam solution. The solution is then piped to the discharge devices protecting the hazard area. Bladder tanks are available in horizontal and vertical mounting with a completely pre-piped option.
The foam tank and the low/medium expansion foam generator construct the low/medium foam spraying system. It can also construct the high expansion total flooding extinguishing system with a high expansion foam generator. It is especially suitable to put out the fire caused by an inflammable liquid tank or large scale of spill fire. This method allows the water/foam ratio to remain stable by automatically adjusting to the variable flow rates and pressure conditions that may occur during system operation. It aims at the fire of class A and class B, especially for the fire of class B. The foam bladder tank mainly applied in occasions such as places where the inflammable liquid was produced, stored and transported. This feature makes bladder tanks particularly suitable for multiple hazard systems, sprinkler systems and any other system operating under variable, nonpredictable, flow and pressure conditions. The foam bladder tank is the main unit of the foam extinguishing system. The device consists of a pressure tank, bladder, proportioner, pressure gauge, valves, and pipeline. A pump is needed to supply pressurized water. When pressurized water flows through proportioner, a small part of water (3%-6%) flow into tank from branch pipe to press the bladder to swap out equal foam concentrate and then mix with another part of water (97%-93%) to form foam solution in proportioner and provide to foam generator.

1. Pre-piped option for easy installation
2. Reversible water inlet direction: Water can be directed from either of the sides
3. Standard Unit comes with pressure gauges, control valve, thermal pressure relief valve, sight glass and fill & drain valves
4. All valve and accessories accompanied with identification name plates
5. Can be offered in flanged or grooved inlet/outlet connection
1. Device should be installed at places with shelter to avoid sun and rain. Ambient temperature should be within 40°C and leave enough space for operation. Device should be installed at concrete floor and fastened with anchor nuts.
2. Do the hydraulic test after installing. Open the tank vent valve first then fill water into bladder from concentrate draining pipe. Then close tank vent valve when bladder is full of water. Pressurize the system and keeping for 10 minutes when pressure gets test pressure, tank should have no leakage. Close water inlet valve and open water drainage valve and concentrate drainage valve to drain water away in tank and bladder. (We will do this test when products leave the factory)
