This high-capacity 211-gallon vessel serves as a critical component in maintaining system pressure stability while protecting against the corrosive and performance-degrading effects of oxygenated water. By utilizing an advanced captive bladder design, the \u003cstrong\u003eTaco CA800-250\u003c\/strong\u003e ensures long-term operational reliability for demanding commercial and industrial applications.\u003c\/p\u003e\u003cp\u003eThe tank operates by utilizing a flexible heavy-duty bladder that separates the system water from the air cushion within the steel shell. Unlike older plain steel tanks that allow air to dissolve directly into the water, this captive air design prevents waterlogging and air absorption, significantly reducing the load on system air vents and decreasing the risk of pipe corrosion and pump cavitation.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperational Pressure:\u003c\/strong\u003e Rated for high-pressure systems up to 250 PSI.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity Rating:\u003c\/strong\u003e Large 211-gallon volume for substantial thermal expansion storage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBladder Technology:\u003c\/strong\u003e Captive air design eliminates air-to-water interface issues.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Protection:\u003c\/strong\u003e Internal separation preserves system water quality and equipment longevity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for large commercial hydronic heating systems, chilled water loops, and industrial process cooling where precise pressure management and oxygen exclusion are required to maintain peak system efficiency.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43136469401694,"sku":"CA800-250","price":11260.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/CA800_250_image_4c13718e-7776-4911-9b6d-e730b214daaa.png?v=1786136968","url":"https:\/\/nationalboilersupply.com\/products\/taco-ca800-250-series-ca-captive-air-expansion-tank-211-gallon-250-psi","provider":"National Boiler Supply","version":"1.0","type":"link"}
