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.\n  \u003c\/p\u003e\n  \u003cp style=\"margin-top: 15px;\"\u003e\n    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.\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Amtrol","offers":[{"title":"Default Title","offer_id":42913134772318,"sku":"1070","price":1750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Amtrol_Extrol_AX-30_Commercial_ASME_Expansion_Tank_heavy-duty_commercial_hydronic_system_component..jpg?v=1782011408","url":"https:\/\/nationalboilersupply.com\/products\/amtrol-ax-30","provider":"National Boiler Supply","version":"1.0","type":"link"}
