PRODUCT DESCRIPTION
The NAFFCO Pre-piped Bladder tank is an integral component of balanced pressure proportioning system. Its operation requires no external power other than a pressurized water system. NAFFCO bladder tank, with an appropriate proportioner, injects foam concentrate into the water supply of a fire protection system and automatically proportions at wide range of flows and pressures. NAFFCO Pre-piped Foam bladder tank is a steel pressure vessel fitted with an Internal Elastomeric bladder that stores foam concentrate. During operation, the concentrate is discharged by incoming water pressure to the bladder tank until the concentrate is depleted. The bladder tank discharges foam concentrate 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.
