Young Engineering has developed a new UL-approved one-gallon, non-repairable Bladder Expansion Tank (BET).
Young Engineering, known for highly engineered, industrial-quality surge and pulsation control products, announced that it has developed a new UL-approved one-gallon, non-repairable Bladder Expansion Tank (BET) designed specifically for the fire protection industry to protect antifreeze sprinkler systems from the damaging effects of thermal expansion. Much like the rest of the Young Engineering BET line, the industrial strength tank can perform at five times the safety factor, ensuring a safe fire protection system. On systems that utilize backflow preventers, overpressure problems can occur when temperature variation (excessive heat) causes the antifreeze to expand, resulting in component damage. Young Engineering BETs alleviate this overpressurization, which can "absorb" the expanding fluid, controlling the pressure to a safe level.
