The foam bladder tank is the main unit of the foam extinguishing system. 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 high expansion foam generator.
It aims at fire of class A and class B, especially for fire of class B. The foam bladder tank mainly applied in occasions such as places where inflammable liquid was produced, stored and transported. It’s especially suitable to put out fire caused by inflammable liquid tank or large scale of spill fire
The device consists of pressure tank, bladder, proportioner , pressure gauge, valves and pipeline. A pump is needed to supply pressurized water. When pressurized water flow through proportioner, a small part of water(3%-6&) flow tank branch pipe to press the bladder to swap out equal foam concentrate and then mix with another part of water(97%-93%) to foam foam solution in proportioner and provide to foam generator.
