Designed to accommodate expanded water volume as temperatures rise, this \u003cstrong\u003eTaco CA\u003c\/strong\u003e model prevents pressure spikes and protects critical system components from fatigue and failure, ensuring a stable and long-lasting installation.\u003c\/p\u003e\u003cp\u003eThis vessel operates using a high-quality diaphragm that separates the system water from the air cushion, effectively maintaining system pressure within safe parameters. By absorbing the volumetric changes inherent in closed-loop heating cycles, it minimizes unnecessary discharge from relief valves and protects pump seals from excessive stress.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Regulation:\u003c\/strong\u003e Maintains consistent system pressure to prevent relief valve discharge.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragm Integrity:\u003c\/strong\u003e Features a heavy-duty, field-replaceable bladder engineered for longevity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Protection:\u003c\/strong\u003e Reduces the risk of localized boiling and cavitation within the piping network.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for use in commercial and high-capacity residential hydronic heating systems, radiant floor heating loops, and chilled water applications where thermal expansion control is mission-critical.\u003c\/p\u003e","brand":"Taco","offers":[{"title":"Default Title","offer_id":43136466944094,"sku":"CA2500-125","price":19634.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/CA2500_125_image_e7fe22c4-227b-42b1-ab85-3c7331e46596.png?v=1786136500","url":"https:\/\/nationalboilersupply.com\/products\/taco-ca2500-125-ca-series-expansion-tank","provider":"National Boiler Supply","version":"1.0","type":"link"}
