Bladder Expansion Tank meets fire protection industry needs.

Press Release Summary:

Able to withstand 5x rated pressure before failure, UL-approved 1 gal non-repairable Bladder Expansion Tank (BET) protects anti-freeze sprinkler systems in commercial and residential applications from damaging effects of thermal expansion. By absorbing expanding fluid, internal system pressure is controlled within safe level. Industrial-strength tank, designed to 175 psi, is manufactured in accordance with ASME code Section VIII, Div 1 and exceeds safety requirements of UL and NFPA.

Young Engineering Introduces UL Approved 1 Gallon Bladder Expansion Tank for Fire Industry

Young Engineering Introduced New Cost-Efficient One-Gallon Bladder Expansion Tank (BET) for Fire Industry UL Approved Product Protects Against Thermal Expansion for Commercial or Residential Applications Young Engineering, known for highly engineered, industrial-quality surge and pulsation control products, has developed a new UL approved one-gallon, non-repairable Bladder Expansion Tank (BET) designed specifically for the fire protection industry to protect anti-freeze 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. "We had more than one goal when designing this one-gallon BET product," said Winston Young, president of Young Engineering. "The simplicity of its design makes it unique. It's compact design makes it easier to fit and install in smaller commercial or residential systems, it's more cost-efficient for those smaller systems and, it still meets and exceeds safety requirements of both UL and NFPA." On systems that utilize backflow preventors, over-pressure problems can occur when temperature variation (excessive heat) cause the antifreeze to expand resulting in component damage. Young Engineering BETs alleviate this over-pressurization can which "absorb" the expanding fluid, controlling the pressure to a safe level. The National Fire Protection Association (NFPA 13) requires the use of expansion chambers in antifreeze systems which use backflow preventors. Young Engineering Bladder Expansion Tank line is manufactured in accordance with ASME code Section VIII, Div. 1. Sizes range from one-gallon to 150 gallon. They are designed to 175 psi design pressure and guarantee a 5X safety factor meaning the product can go to five times the rated pressure without failure.
