Bladder Expansion Tank
Brand: Young Engineering Manufacturing, IncBladder Expansion Tanks for fire protection are designed with a gas filled bladder inside to absorb the liquid expanding within a building’s closed loop fire sprinkler system and meets the needs of NFPA 13. These UL approve Glycol and Glycerin tanks protect anti-freeze sprinkler systems from the damaging effect of thermal expansion during changing weather conditions.
Systems that utilize backflow preventers can suffer from over-pressurization when excessive heat or cold causes the antifreeze within the fire sprinkler lines to expand resulting in sprinkler system damage.
This over-pressurization can be alleviated with a Young Engineering UL Listed bladder expansion tank which “absorbs” the expanding fluid, controlling the pressure to a safe level. When the fluid contracts due to temperature cooling, the bladder expansion tank expels the fluid back into the system.
