CHEMGUARD 25 & 36 Gallon Bladder Tanks are a steel pressure vessel which stores 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 foam concentrate, supplying pressurized foam concentrate to the proportioner.
Application
The CHEMGUARD 25 & 36 Gallon Bladder Tanks are one component of a balanced pressure proportioning system. These small systems could include backup generator fuel storage in high rise buildings and hospitals or other small flammable liquid storage areas. CHEMGUARD 25 & 36 Gallons Bladder Tanks require only a pressurized water supply for operation. No other external power is required
Features
- UL Listed and FM Approved for use with various CHEMGUARD proportioners and foam concentrates
- Large, removable cap for easy filling
- Choice of Standard or Corrosion-Resistant Epoxy exterior paint, available in a variety of colors
- Standard high-build epoxy internal coating suitable for use with fresh or seawater
Approvals and Certifications
All CHEMGUARD 25 and 36 Gallon Bladder Tank configurations are UL Listed and FM Approved for use with various CHEMGUARD foam concentrates. The UL mark and FM diamond are applied at the factory along with a label identifying the CHEMGUARD foam concentrate for use in the tank.
Every tank bears a permanently affixed ASME data plate showing the National Board number which identifies the tank as compliant with ASME code Section VIII, Division 1 for unfired pressure vessels.
CHEMGUARD 25 and 36 Gallon Bladder Tank configurations are not CE marked. Under European Pressure Equipment Directive 2014/68/EU, tanks smaller than 200 gallons are acceptable based on sound engineering practices of ASME code and cannot be CE marked.
