Platinum Foam System

Description

• 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)
