Bladder Foam Tank
It is a tank for storing foam liquid installed with a pressure proportioner or a diaphragm pressure proportioner. A bladder bag is installed inside the tank, so foam liquid is stored inside the bag.
The stored foam liquid is pushed by the pressure in the water supply line to be discharged and mixed with fire water. A tank is made of carbon steel. The inner wall is not in contact with the foam liquid but is in contact with water, so it is coated with anti-corrosion coating to prevent corrosion. The built-in bladder bag is made of a material that is not hardened or aged by the foam liquid and is not damaged by pressure, so that the lifetime is longer and more stable.
