concentrate .During operation ,water supplied to the bladder tank displaces the foam concentrate and
collapses the bladder until the concentrate is depleted .
The bladder tank discharges foam concentrate is at approximately the same pressure as the water
supplied at the water inlet connection to the tank .Since the bladder tank is pressurized , the bladder
should not be refilled during operation .Frequently used in aircraft hangars ,loading racks ,sprinkler
system , and offshore platforms.
of China and ISO, This kind of steel is suitable for the welding and construction of tanks for fire fighting foam proportioning system utility.
2) Bladder in nitrile butadiene rubber and polyester, available of the tensile strength that ensures no
ruptures under operation conditions.
3) Main valves are made of corrosion resistant stainless steel.
4) Pipe networks made of seamless steel pipe. The inlet and outlet of ratio controller will be in DN100 (4")
with a pressure from 6 bar up to 12 bar.
