200L-10000L fire foam bladder tank
Introduction
Foam bladder tank, together with ratio controllersSpecialized Case & Box , form a balanced pressure proportioning system used to mix water and fire fighting foam together to generate an effective extinguishing medium.The bladder tank technology is a mixing method allows the water/foam ratio to remain stable by automatically adjusting to the variable flow rates and pressure conditions that may occur during system operation.This feature makes bladder tanks particularly suitable for multiple hazard systems, sprinkler systems and any other system operating under variable, non predictable, flow and pressure conditions.
Function
The bladder tank is a carbon steel pressure vessel containing an elastomeric separation bladder between the water and foam concentrate. The bladder permits water pressure to be transferred to the foam concentrate without the two fluids mixing together. A ratio controller generates a water pressure drop by means of a reduced cross section where the water stream passesDrying Machine through it. As the foam concentrate pressure is higher than the pressure at the ratio controller, the foam starts flowing towards the water and mixing at a caElectronics Stocks librated rate, which is dependant on the water flow rate.
