The ANSUL bladder tank is a steel pressure vessel which stores a foam concentrate contained within an elastomeric bladder. The concentrate is discharged from the tank by incoming water applying pressure to the bladder. This applied energy is transferred to the concentrate, supplying pressurized concentrate to the proportioner. —

ANSUL bladder tanks are available in both vertical and horizontal tank models and a variety of nominal capacities as listed in the tank information tables. Both tank models feature perforated center tubes which allow improved agent discharge.

Features incorporated into the ANSUL bladder tanks include the following:

– Water pressurized bladder construction, alleviating the requirement for foam pumps or other energy sources

-Valves that are pinned in the normal operative positions and are supplied with nameplates identifying their functions and operating instructions

-Bladder tanks are supplied with corrosion-resistant piping

-Exterior tank surfaces finished in red standard system paint or coated with an epoxy “CR” red finish for use in marine or corrosive environments

-Tanks with a high build epoxy coated interior for use with both fresh and salt water
