The Amtrol Extrol AX-30 Commercial ASME Expansion Tank (AX-30) is a high-performance system component engineered to deliver premium fluid distribution efficiency and reliability. Built with a heavy-duty deep-drawn steel housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for controlling pressure changes in closed commercial hydronic heating and cooling configurations.
Constructed and certified per ASME Section VIII, Division 1 code standards, the AX-30 features a premium deep-drawn dome engineering design that offers double the physical strength of traditional head-and-shell designs while minimizing systemic weld points. The internal architecture features a heavy-duty, fixed butyl diaphragm that permanently separates the system fluid from the pre-charged air chamber, preventing waterlogging and maintaining structural system balance. Outfitted with a heavy-gauge steel shell and factory-finished with a rugged red-oxide primer layer, this inline commercial expansion tank ensures continuous thermal expansion protection and rigid building code compliance.
