Extrol Expansion Tanks

Extrol expansion tank series are used for closed loop hydronic (baseboard/radiator/etc.) and radiant floor heating applications. They are typically connected to the supply line near the boiler or directly to an air eliminator (smaller models).
All Extrol tanks are factory pre-charged at 12 psi and come in system-mount or floor standing models.
