Foam Bladder Tank

Function Description

The IJFFG bladder tank is a carbon still pressure vessel containing an elastomeric separation bladder between the water and foam concentrate .The bladder permits water pressure tube trans feed to the foam concentrate without the two fluids mixing together.

A IJFFG ration controller, as described in a separate date sheet, generates a water pressure drop by means of a reduced cross section where t water stream passes through it . As the foam concentrate pressure is higher than the pressure at the taction controller , the foam starts flowing towers the water and mixing at a calibrated Tate which is dependent on the water flow rate.

Construction Features

Application:

The IJFFG bladder tank, together with ration controllers , form a balanced pressure proportioning system used to mix water and fire fighting foam together to generate an effective extinguishing media to mix water and fire fighting foam together to generate an effective extinguishing medium.

The bladder tank technology is a reliable and precise mixing method that is wide spread in the fire fighting industry. This method allows the water/foam ration to remain stable by automatically adjustin the variable flow rates and pressure conditions that may occur durinosystem operation.

This feature makes bladder tank particularly suitable for multiple hazard systems ,sprinkler systems and any other system operationg under variable , non predictable flow and pressure conditions.
