Product Description

INTRODUCTION
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 is especially suitable to put out fire caused by inflammable liquid tank or large 
scale of spill fire.


PRINCIPLE
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 though 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.

INSTALLATION
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.
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)
