Description:
UL and FM Approved Surge Suppressors protect fire systems from damaging surges caused by pump startup and shut down. NFPA 13 requires the use of expansion chambers with backflow preventers. Backflow preventers stop antifreeze from flowing back into water supply but problems occur when pressure builds in the system as a result of thermal expansion from temperature changes. This over-pressurization can be alleviated with Young Eng. Bladder Expansion Tanks.
