In old style, plain steel tanks, the direct air-to-water interface can allow the air to be absorbed into solution and carried to other parts of the system. The results can be waterlogged tanks, air-bound terminal units, excessive corrosion, inefficient balancing and pump cavitations.\u003cbr\u003e \u003cbr\u003e Not so with Taco CA Series Tanks. In this design, the air is held captive on the shell side, with all expanded fluid directed into the bladder (in CA models) or the diaphragm chamber (in the CX Series). Air and water are permanently separated, so no absorption can take place during the system cycle. \u003cbr\u003e \u003cbr\u003e Properly sized, selected and located air separation and removal components can provide a stable, tight and closed hydronic system. In most properly-sized CA systems, you can reduce the tank size by 80% compared to the old style, plain steel tanks. \u003cbr\u003e \u003cstrong\u003e\u003cbr\u003e CA Series Tank features include:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"\"\u003e\u003c\/p\u003e\u003cul style=\"\"\u003e\n\u003cli\u003eHeavy-Duty Butyl Rubber Bladder, Removable for Inspection\u003c\/li\u003e\n\u003cli\u003eFull Acceptance Vessel\u003c\/li\u003e\n\u003cli\u003eShell: Fabricated Steel, Designed and Constructed per ASME Section VIII Div. 1\u003c\/li\u003e\n\u003cli\u003eStandard Bladder: 125 PSIG (862 kPa)\u003c\/li\u003e\n\u003cli\u003eOptional Bladder: 150 PSIG (1,034 kPa)\/250 psig (1,723 kPa)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cspan style=\" font-weight: bold;\"\u003e\u003cbr\u003e Product Manuals and Downloads:\u003c\/span\u003e\u003cspan style=\"\"\u003e\u003cbr\u003e \u003c\/span\u003e\u003cul\u003e\n\u003cli\u003eTaco CA Expansion Tanks Catalog\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan style=\"\"\u003eCA Expansion Tanks \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eTaco CA Expansion Tanks Specification Sheet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":47344086024365,"sku":"50264","price":4900.96,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/Taco_CAExpansionTanks_CA140Pic.jpg?v=1787917898","url":"https:\/\/www.bostonheatingsupply.com\/products\/taco-ca140-captive-air-ca-expansion-tank-37-gallon","provider":"Boston Heating Supply","version":"1.0","type":"link"}
